1.1 PRODUCT DESCRIPTION
The Voltage Input Module (VIM), which is shown in Figure 1-1, is an I/O element of the APACS+
Advanced Controller. It is an intelligent (microprocessor-based), configurable module, which interfaces
thermocouple and voltage input signals with an APACS+ control module’s IOBUS. Figure 1-2 illustrates
basic input wiring.
The VIM:
•Minimizes hardware costs with 16 software-configurable channels (thermocouple or voltage input)
•Improves accuracy and simplifies configuration with integral linearization, autoranging, self-
calibration, and cold junction compensation
•Facilitates faster response to field problems with a configurable burnout detection feature (up or down
scale)
•Provides greater protection against short circuits via individually isolated channels
•Supports redundant architecture for high availability
•Reduces servicing time by allowing the module to be inserted or removed while powered without
disturbing field wiring
•Isolates field faults by electrically isolating all input channels from the backplane and ground
•Complies with the European Union’s Electromagnetic Compatibility (EMC) Directive, which requires
process control equipment to be immune to electromagnetic interference (EMI) and limits the amount
of electromagnetic emissions (see module specifications in Table 6-2 for more detailed information)

INTRODUCTION SD39VIM-2
July 19981-4
1.1.1 Channel Types
The VIM provides 16 channels, each of which can be configured to be a thermocouple or voltage input.
Several standard features allow the VIM to accommodate many input types with minimal configuration
and high accuracy, such as:
•Automatic linearization for thermocouple types J, K, E, T, R, S, B, N to user-selectable engineering
units, such as °C, °F, °K, or °R
•Cold junction compensation provided for all thermocouple input measurements
•Autoranging input circuitry for thermocouple inputs, eliminating the need to specify a temperature
range while maintaining high accuracy
•Self-calibration feature eliminating the need for field calibration
•Integral burnout detection to determine if a thermocouple has opened or, if, due to aging, its resistance
has increased
In addition, the VIM’s configurable channels reduce hardware costs and spare parts requirements by
allowing one module to accommodate several input requirements.
1.1.2 Diagnostics
The VIM is designed to provide years of trouble-free service. However, in the event of unexpected
operation, the VIM is equipped with extensive self-diagnostics. The goals of these diagnostics are to:
•Notify the appropriate personnel of a module malfunction or wiring error
•Perform automatic switchover in a fully redundant (1oo2D) APACS+ system
Any errors detected by these diagnostics are reported to the associated control module. The control module
and the VIM maintain a log of current and historical errors that can be reviewed using the Diagnostic
Logger Utility or the 4-mation configuration software. In addition, errors are indicated by the module’s
®
LED indicators.
There are two types of circuit diagnostics: those diagnostics that monitor overall module performance,
which are common to all I/O modules, and those that cover individual input channels.
1.1.2.1 Overall Module Performance Diagnostics
Diagnostics for overall module performance include failure detection in the communications, processor,
and common circuits. These diagnostics include:
•Power supply diagnostics (monitor the three 24 Vdc power input busses for under voltage and the
onboard isolated power supply for voltages within tolerance)
•Over temperature diagnostics (check the module for over temperature conditions via an online
monitor)
•Memory diagnostics [run a complete IEEE published test on RAM memory at module startup, detect
RAM failure modes in the optimal amount of time via galpat tests, and verify critical RAM data and
ROM memory online with cyclical redundancy checking (CRC)]
SD39VIM-2 INTRODUCTION
July 1998 1-5
•Communication diagnostics (verify IOBUS communications for each message via CRC)
•Redundancy diagnostics (monitor logic signals for valid combinations, compare redundancy status
information from the IOBUS with logical signals on the module, reporting any discrepancies as errors)
•Watchdog timer diagnostics (detect processor operation failures via external and CPU hardware timers
and monitor IOBUS and scanning operation via additional timers)
•CPU diagnostics (run manufacturer-supplied tests on CPU components, where results from the
instruction sequences must match predetermined values)
•Software diagnostics (verify program flow control to ensure that software functions execute in proper
sequence and time, perform data integrity checks, and compare data to predetermined ranges)
•Addressing diagnostics (compare module slot/rack addresses against their addresses at startup)
1.1.2.2 Input Circuit Diagnostics
Redundant isothermal sensors on the termination strip are compared to detect failures. To detect excessive
drift failures, duplicate voltage references are also compared, while amplifiers and A/D converter circuits
are continually automatically recalibrated online. Any component failures that require abnormal
calibration correction are also detected. Input source impedance is monitored for up and down scale
thermocouple burnout detection and fault detection for other components.
1.1.3 LED Indicators
The VIM’s LEDs support local troubleshooting without an operator interface. The module includes two
LEDs that indicate a combination of two of the following module statuses:
•Module OK
•Channel(s) faulted
•Module faulted
•Module unconfigured
•IOBUS communication failed
•Module failed
•Module active (calculate mode)
•Module inactive (verify mode)
1.1.4 Configuration
Like all APACS+ I/O modules, the VIM is configured using the 4-mation software. The configuration is
loaded into the module’s memory, and a copy of the configuration is stored in the associated control
module’s non-volatile memory. This approach to configuration allows the module to be removed and
replaced on-line without the need for reconfiguration.
During configuration, 4-mation is used to assign a type to each channel (thermocouple input or voltage
input) and several parameters which vary according to channel type.
INTRODUCTION SD39VIM-2
July 19981-6
1.1.4.1 Thermocouple Input Channel Parameters
•Thermocouple Type (J, K, E, T, R, S, B, or N)
•Engineering Units (°C, °F, °K, °R)
•Bias (in engineering units)
•Minimum and Maximum Scale
•Burnout (upscale, downscale, or no detection)
•Digital Filter Time Constant
•Step Response Time (defines the time for a moving aver-age digital filter for the input signal, thus
specifying the time to fully respond to an input step; this filter reduces periodic noise and improves
repeatability and resolution)
1.1.4.2 Voltage Input Channel Parameters
•Input Range (1 to 5 Vdc, 0 to 5 Vdc, -10 to 10 Vdc, -5 to 5 Vdc, -1 to 1 Vdc, or custom range between
-10 and 10 Vdc)
•Minimum and Maximum Scale
•Engineering Units
•Digital Filter Time Constant
•Step Response Time
1.1.5 Terminations
The VIM’s field I/O can be terminated locally or remotely according to user needs and preferences. Local
terminations reside directly below the VIM. Marshalled Termination Assemblies or Rail Termination
Assemblies provide for terminations up to 100 feet (30.5 m) away from the VIM. Figure 1-2 is an example
of the wiring used for any of these options.

2.2 CONSIDERATIONS AND PREPARATION - See Danger Alert on the last page
Read sections 2.2.1 and 2.2.2 before continuing with the VIM installation. Section 2.2.1 describes
considerations required to ensure that the modules are compliant with the European Union’s
Electromagnetic Compatibility (EMC) Directive.
2.2.1 EMC Directive Installation Considerations
Some installations of VIM modules may require adherence to the European Union’s Electromagnetic
Compatibility (EMC) Directive. Refer to the “Declaration of Conformity” statement at the back of this
document that lists the certificate number of the Technical Construction File issued to the Voltage Input
Modules. Compliance with the Directive requires some or all of the following:
•APACS+ systems must use enclosures having sufficient RF attenuation.
•AC power input conductors to the enclosure must be filtered.
•MODULBUS (M-BUS) cables that enter or exit the enclosure must be filtered.
•The “shield” of all shielded cables that exit the enclosure must be connected to the enclosure.
Consult the factory for additional information concerning EMC Directive installation and the availability
of enclosures and needed hardware.
2.2.2 Preparations
1. Install the MODULRAC, SIXRAC, or UNIRAC and the Local Termination Panel (for local
termination only) in the cabinet where VIMs are to be installed. VIMs should not be installed in the
rack at this time, however, the rack address (1 TO 16) and rack slot numbers (1 to 10) for VIM
installation should be known.
2. If local I/O termination is employed, tag all I/O cables and route them into the cabinet. They should be
ready for cable end preparation and connection to the VIM Termination Strips. Cable wire sizes: 14 to
26 AWG (American Wire Gage).

3. If remote I/O termination is employed, complete the following:
1) If Marshalling Utility Panels are being used, install them in their respective marshalling cabinets.
2) Tag all I/O cables and route them into the marshalling cabinet. They should be ready for cable end
preparation and connection to the VIM Marshalled Termination Assemblies (cable wire sizes: 10
to 26 AWG) or user supplied termination assemblies. User supplied termination assemblies
require a VIM Temperature Transducer Kit and an unterminated Interconnect I/O Cable. The
VIM Temperature Transducer Kit is listed under "Accessories" in section 5.2 of this Instruction.
3) Route the Interconnect I/O Cable (or Unterminated I/O Cable) between the marshalling cabinet
and the cabinet and rack in which the VIM will be installed. Refer to Figure 1-1; J1 will be
installed in the rack and P2 will connect to the VIM Marshalled Termination Assembly in the
marshalling cabinet.
4) If an Unterminated I/O Cable is installed, user-supplied terminations (e.g. terminal blocks) must
be installed for field signal input wiring and the I/O Cable.
4. A dedicated, reliable, electrically clean power source should be furnished by the user to power field
devices providing voltage input signals. An uninterruptible power supply (UPS) can be installed for
increased reliability and power quality.
VIM input channels are isolated from one another, thus permitting voltage inputs to each channel to
originate from dedicated, separate power sources.
High-power EMI-producing equipment should not be connected to any power lines dedicated to VIM
input signals. See inserted Page 2-3a
2.3 ENVIRONMENTAL CONSIDERATIONS
•Many industrial environments create severe operating conditions. The conditions at each VIM
location must be within the specifications stated in section 6.2.
CAUTION
Exceeding the specified operating temperature limits can adversely affect
performance and may cause damage. Air temperature should be
periodically checked to ensure that this specification is not being
exceeded.
•To ensure operator safety, VIM Marshalled Termination Assemblies shall be installed in enclosures
which require a key or special tool to gain access to the equipment.
Change Since Revision 1
Add to Section 2.2.2 item 4.
WARNING!
Arc welding to surfaces with attached, active thermocouples can damage VIM
termination transducers. Remove VIM from rack or disconnect I/O wiring from VIM
termination before welding.
INSTALLATION SD39VIM-2
July 19982-4
•To ensure reliable data communications, it would be prudent to locate APACS+ equipment as far as
possible from sources of interference such as high current electrical equipment which emit strong
electromagnetic fields and switching transients.
2.4 EQUIPMENT DELIVERY AND HANDLING
The following subsections provide information of interest to shipping, receiving, and warehouse personnel.
2.4.1 Predelivery Test
An VIM is fully tested and inspected to ensure proper operation. If the VIM is ordered factory installed in
a MODULPAC or other enclosure, the VIM is tested as part of the overall APACS+ process automation
system and inspected to ensure proper operation.
2.4.2 Factory Shipment
VIMs to be installed by the user are placed in static shielding bags and packaged for shipment.
Accessories are packaged separately. If the VIM is ordered factory installed in a MODULPAC or other
enclosure, the enclosure is bolted to a pallet and wrapped for protection during shipment.
2.4.3 Receipt of Shipment
All cartons should be inspected at the time of their delivery for possible external damage. Any visible
damage should be immediately recorded on the carrier’s copy of the delivery slip.
Each carton should be carefully unpacked and its contents checked against the enclosed packing list. At
the same time, each item should be inspected for hidden damage that may or may not have been
accompanied by exterior carton damage.
If it is found that some items have been damaged or are missing, refer to sections 2.4.4 or 2.4.5 and notify
Moore immediately, providing full details. In addition, damages must be reported to the carrier with a
request for their on-site inspection of the damaged item and its shipping carton.
2.4.4 Equipment Handling
The VIM is completely enclosed and may be safely handled without undertaking special ESD (electrostatic
discharge) handling procedures provided the bezel compartment door is closed and secured. DO NOT
touch the connector pins on the back of the module.
SD39VIM-2 INSTALLATION
July 1998 2-5
CAUTION
Use a grounded wrist strap to provide ESD protection whenever the
module’s bezel door is opened.
2.4.5 Equipment Storage
The storage temperature and humidity parameters of section 6 must be met for storage of an VIM.
2.5 VIM TERMINATION STRIP INSTALLATION
Install a VIM Termination Strip at the rack slot location of each VIM when local I/O termination is
employed. As shown in Figure 2-1, a Local Termination Panel must be installed.
NOTE
On the Termination Strip, delicate temperature sensors U1/U2 are
mounted at each end of the terminal block. Handle the Termination Strip
carefully to avoid sensor damage.
Refer to Figure 2-1 and the following mounting instructions:
1. Consult user’s or system integrator’s rack documentation and note the slot locations assigned to each
VIM in each rack.
2. Note the following on a rack or a Termination Strip:
•On a rack, locate and identify the extruded spacer to which the lower edge of the backplane is
mounted. Note that the bottom of the extruded spacer is grooved. The top edge of a Termination
Strip will rest in this groove.
•Identify a series of alignment pins located below the rack frame that span the width of the rack
panel. One of these pins will engage a hole located on the Termination Strip above the MOORE
logo. The left-most pin corresponds to rack slot #1.
•The Termination Strip’s captive mounting screws can be seen projecting from the bottom of the
plastic extrusion panel.
INSTALLATION SD39VIM-2

2.6.3 Interconnect I/O Cable Installation
An Interconnect I/O Cable (Figure 2-6) is used to connect each VIM to a VIM Marshalled Termination
Assembly when remote I/O termination is employed. The cable-to-module connector (J1) is installed at
the rack slot location of a VIM. It is assumed that as part of the site preparation procedure all tagged
Interconnect I/O Cables have been routed and pulled into their respective cabinets and are ready for
connection. An Unterminated I/O Cable is installed similarly at the rack, however, terminations in the
marshalling cabinet are user-supplied .
VIM Marshalled Termination Assemblies should already be installed in the marshalling cabinet (see
section 2.6.1) and be ready for cable connection. Refer to Figures 2-1 and 2-6 and the following
procedure:
1. Note the following on the cable’s molded J1 connector.
•The lower face area of J1 has a “pin mounting hole” located above a captive mounting screw.
This hole engages one of the rack panel’s alignment pins.
•The top edge of J1 will rest in the groove of the backplane’s extruded spacer as illustrated by a
detail in Figure 2-1.
2. Consult user’s or system integrator’s documentation and note the MODULNET node address (if
applicable), rack address number (1-16), and slot number assigned to the VIM. J1 will be installed at
this location.
3. Install J1 at its assigned location as follows:
1) Angle the top edge of the molded connector toward the backplane’s extruded spacer and insert its
tip in the spacer’s groove.
2) Slide the connector in the groove until it is vertically and horizontally aligned with the appropriate
pin (slot #).
3) Carefully lower the molded connector and engage the alignment pin with the connector’s pin
mounting hole. Firmly push down to seat the connector on the pin. When the connector is
properly seated, the pin will be flush with or project slightly above the face of the connector.
4) Secure the connector to the rack panel with its captive mounting screw which is automatically
aligned with its panel mounting hole.
5) Get two labels from the bag of VIM labels. Record on each label the appropriate numbers noted in
the above step 2 (Figure 1-1). Attach one label each to the molded J1 and the P2 connectors.
4. Key cable connector P2.
Get the P/N 16056-435 Cable Keying Kit set aside in step 2 of section 2.6.1. The kit contains keying
pins and an instruction. Refer to Figure 2-6 for the assigned keying pattern and install the pins as

diagrams to make the proper cable connections to the termination assembly.
6. On redundant VIMs only, connect the redundant I/O Cable as described in step 5 above.
2.7 VIM INSTALLATION
Modules are shipped individually packaged in protective, sealed, static shielding bags. Refer to section
2.4.4 for module handling considerations. Section 2.7.1 describes keying a rack slot. Section 2.7.2
describes installing the module in the rack.
Each rack slot and each module must be keyed to prevent accidental installation of a module into an
incompatible slot which may impair system performance. Keying is highly recommended; see Figure 2-7.
•Modules are keyed at the factory. The keying pattern is unique to each module type (e.g. ACM, CCM,
CDM). See Figure 2-7 for the VIM keying pattern.
•A factory assembled rack is keyed at the factory. A user-assembled rack is keyed by the user
according to the module type assigned to each slot. This keying pattern complements the module’s
keying pattern. Stop plugs are supplied with the rack.
•When adding a module to a rack, be sure to key the rack slot.

2.8 ELECTRICAL INSTALLATION
This section describes field signal input connections to a locally mounted VIM Termination Strip and to a
remote mounted VIM Marshalled Termination Assembly. It is assumed that tagged field I/O wires have
been pulled into the cabinet and are ready for preparation and connection.
2.8.1 Field Input Wire Selection
A VIM Termination Strip and a VIM Marshalled Termination Assembly provide for connection of up to
16 pairs of configurable voltage, millivoltage, or thermocouple inputs. For voltage and millivoltage type
inputs, the recommended cables are given in Table 2-1.

2.8.2 Field Input Wiring Connections
Figure 2-9 shows typical input connections. Both the local and remote termination assemblies provide for
connection of up to 16 channels of voltage, millivoltage, or thermocouple input. Each termination
assembly is arranged as follows:
•Long input signal terminal block with 32 terminals (two terminals per channel).
•The channels are consecutively numbered 1 to 16. Refer to Table 2-3 for terminal identification.
•Each channel is electrically isolated from other channels.
•Two short grounding terminal blocks on either side of the input signal terminal block. These terminals
are used to ground the cable shields.
Refer to the following for input signal wiring:
1. Refer to the user’s or system integrator’s Process and Instrumentation Drawings to determine required
cable connections for I/O power supplies and all field devices. Refer to Table 2-3 for connection data.
2. Prepare the shielded input signal cables as illustrated in Figure 2-10.

3. Use the following recommendation to prepare wire ends for connection of I/O power supplies (as
necessary) and field devices to terminal blocks.
•Do not solder multiple wires or the strands of multiple-strand wires for insertion into DIN rail
terminal blocks. Solder is a malleable material and can loosen, causing open connections. Also,
corrosion to the terminal block can result from the pickling agents or flux used with solder.
•Use a pin-type crimp-on connector when two or more wires or a combination of wires and
component leads (for example, resistors and stranded or solid wire) must be inserted into a DIN
rail terminal block. Also, use a pin-type crimp-on connector for connections that will be moved
regularly.
Wires and leads are crimped into the terminal and the terminal pin is inserted into the selected
connection. Moore recommends the use of insulated crimp-on connectors available from electrical
supply sources. Figure 2-8 shows an example of the use of a crimp-on connector.
NOTE
Use a crimping tool recommended by the connector manufacturer to
ensure a strong mechanical, low electrical resistance connection.
FIGURE 2-8 Using a Pin-type Crimp-on Connector
4. Use the following torque specifications when connecting terminals in DIN rail terminal blocks:
CLMI (gray) DIN rail terminal blocks: 3.5 to 5.5 in. lbs.
CPhoenix (green) DIN rail terminal blocks: 6.5 to 8.5 in. lbs.
5. Complete the necessary connections for each configured channel.

Connect field devices to user-supplied terminations. Table 2-4 lists the wire color and identification
information needed for termination. Refer to user wiring diagrams as necessary.
WARNING
Electrical shock hazard. Remove power from all involved wires and
terminals.
2.8.4 Configuration
The VIM and its associated control module must be configured before being placed on-line. Details are
provided in the ProcessSuite 4-mation Configuration Guide (UM39-14).
After the initial VIM power-up routine has been successfully completed, the VIM’s OK LED will flash
green and black (OFF) indicating an unconfigured module. When the control module recognizes that the
VIM is on-line, it will automatically download the proper configuration to the VIM. When the config-
uration is accepted, the OK LED will be set to solid green.
If the VIM is non-redundant, the control module will ENABLE the VIM by setting its ACTIVE LED to
solid green, thereby placing it in service. If the VIM is one of a redundant pair and the other VIM is in
service, the control module will DISABLE (ACTIVE LED = OFF) the VIM and place it in the standby
mode.
2.9 APACS+ CALIBRATION VERIFICATION REQUIREMENTS — LONG TERM DRIFT
The APACS+ analog I/O is designed to minimize calibration drift and the need for re-calibration over the
life of the product. Design improvements include:
•Elimination of adjustable potentiometers
•Elimination of adjustable resistors
•Use of high quality low drift components
Calibration is performed through mathematical compensation within the microprocessor program. This
allows the use of matched resistors for voltage dividers and minimizes the problem of temperature
coefficient matching.
INSTALLATION SD39VIM-2
July 19982-26
Because the other sources of drift have been minimized, the dominant contributor to analog long term drift
for all analog modules is the voltage reference used for the A/D or D/A circuit. Manufacturer data
specifies a typical long term drift in terms of the first 1000 hours of operation. Typically, drift for the next
1000 hours will be less. In fact, studies have shown that the I/f noise model is valid for long term drift.
This model indicates that the drift will be proportional to the square root of the time period as a limiting
factor.
20ppm drift over the first 1000 hours is a typical drift for a high quality reference such as used in all
APACS+ analog modules. Using 30ppm to account for the other secondary drifts, such as precision
resistor ratios, indicate it would, on average, take 126 years for a module to drift 0.1% from original
calibration due to this mechanism. Drift of 0.05% would on average take 31 years.
Long term drifts significantly greater than typical would be due to flaws inherent to the manufacturing
process of the individual components or the module itself. APACS+ screens out even these unlikely
occurrences through multiple additional layers of control. In addition, the range of compensation is
restricted to prevent compensation for inherently defective devices. All APACS+ modules go through
environmental stress screening before functional testing and calibration to precipitate failure of weak
components. Finally, all APACS+ modules go through an elevated temperature burn-in followed by a
final functional verification including calibration.
For these reasons, Moore does not recommend the need for periodic verification of analog calibration
more often than once every ten years if the system design can accommodate a 0.1% drift from
original calibration. This recommendation is based on the assumption that specified limits for the
modules have not been exceeded.
Calibration-related error messages and/or known over stress conditions being applied to analog I/O points
could indicate the need for verification before the end of a ten year period.

3.0 MAINTENANCE - See Danger Alert on the last page
The APACS+ Voltage Input Module (VIM) and its associated assemblies require minimal maintenance.
Some routine maintenance is recommended in the form of a visual inspection and a possible cleaning.
3.1 TOOL AND EQUIPMENT REQUIREMENTS
The following tools and equipment are necessary for servicing:
•Common electronic servicing hand tools
•Digital Multimeter
3.2 VISUAL INSPECTION
The VIM and its associated assemblies should be subjected to a periodic visual inspection. The frequency
of inspection will depend on the severity of the operating environment. The primary aim of the inspection
is to reveal any excessive accumulation of dust, dirt, or other foreign material adhering to the surfaces of
the VIM Termination Strip and protective covers of the VIM. Accumulation of dirt and dust prevents
efficient heat dissipation and may cause module or system failure. An VIM installed in a cabinet
complying with the NEMA 12/IP55 specification need not be inspected for cleanliness. Refer to section
3.3 for cleaning instructions.
3.3 CLEANING
Cleaning a VIM involves brushing or vacuuming the protective covers to restore cooling efficiency that
may have been degraded by accumulated dust.
Cleaning a VIM Termination Strip or VIM Marshalled Termination Assembly involves careful brushing
and vacuuming to remove accumulated dust and dirt harboring chemical particulate that may accelerate
terminal or connector contact corrosion. Be careful not to disturb the wiring.
3.4 TROUBLESHOOTING
Errors are annunciated by a module’ s status LEDs and displayed as error codes and messages in 4-mation.
The VIM’s status LEDs are located on its bezel. For a description of the error codes and messages, refer
to Module Diagnostic Error Codes (document CG39-19, located in binder UM39-14). Troubleshooting
entails observing the status LEDs and reading the error codes and messages, then referring to Table 3-1
and configuration guide CG39-19 to determine the course of action.
Interconnect I/O Cable pin assignments are given in Table 2-2. These are provided for troubleshooting a
suspect cable. As necessary, check field wiring and field located devices.

SD39VIM-2 CIRCUIT DESCRIPTION
July 1998 4-1
4.0 CIRCUIT DESCRIPTION
The following subsections describe the various circuit elements of the VIM and the processing of a
thermocouple input signal. Processing of a voltage input signal is similar except the thermocouple burnout
detection and temperature sensor selection are not applicable. Most VIM functions are performed or
controlled by the CPU. A block diagram of the VIM is shown in Figure 4-1.
The VIM consists of the following circuit elements:
•16 Voltage Input circuits—Process analog input signals.
•16 Channel Multiplexer—Performs time-division multiplexing of input signals.
•Programmable Gain Amplifier—Performs on-the-fly signal conditioning of each input channel.
•Analog-to-Digital Converter—Converts analog input signals to digital data.
•Calibrator—Provides precision calibration voltage.
•TC Burnout Detector—Indicates when a TC fails.
•Sensor Selector—Provides ice point temperature reference signal for TC inputs.
•CPU—Performs general control functions and digital data interfacing to IOBUS .
•Memory (RAM and EPROM)—Stores module configuration parameters.
•IOBUS Modem—Provides digital data and command conversion needed for communication.
•LED Indicators (on module bezel)—An ACTIVE LED indicates that the module is enabled. An OK
LED indicates the module status.
•Power Supply—24 Vdc to multi-voltage dc converter
4.1 THERMOCOUPLE INPUT CIRCUITRY
Pairs of thermocouple wires are connected to terminal blocks mounted on an isothermal (same
temperature) assembly on either style of VIM termination assembly. The wires themselves create two
dissimilar metallic junctions which generate a thermal EMF (offset) proportional to the junction's ambient
temperature. This offset becomes an unwanted addition to the input signal.
The isothermal assembly is an electrical insulator but a good heat conductor and serves to hold both
junctions to the same temperature. The metallic junctions take the place of an “ice bath” and become a
Reference Junction. In order to determine the true junction temperature of the field thermocouple, the
VIM must compensate the input signal for the reference junction offset.
To do this, the VIM must be able to sense the temperature of the isothermal assembly where the TCs are
connected. Two Sensors mounted on the isothermal assembly provide this information to the VIM.
CIRCUIT DESCRIPTION SD39VIM-2
July 19984-2
FIGURE 4-1 VIM Block Diagram
SD39VIM-2 CIRCUIT DESCRIPTION
July 1998 4-3
4.2 SENSOR SELECTION
Two temperature sensors on the Isothermal Assembly are electrically isolated from, but thermally coupled
to, all thermocouple terminals. These sensors sense the top and bottom temperatures of the terminating
blocks and produce a precision 1 mV/CEoutput signal.
The CPU periodically switches on the Sensor Selector which inputs the combined SENSOR OUT signals
into a Programmable Gain Amplifier for amplification and A/D converter for digitizing. The digitized
reference junction signal is fed into the CPU where the software determines the offset (mV) as referenced
against the ice point temperature. When the CPU reads the thermocouple signal, it subtracts the offset
from the signal. The CPU then converts this signal voltage into a temperature.
4.3 MULTIPLEXING, AMPLIFICATION, AND DIGITIZING
Thermocouple generated millivolt (mV) signals from the isothermal assembly are fed into isolated
channels of a 16 channel multiplexer. The output from the Multiplexer (MUX OUT) is fed into a
Programmable Gain Amplifier (PGA) whose gain is controlled by the CPU. The gain is automatically
adjusted (autoranging) to match the input signal to the full scale range of the A/D converter to provide
maximum accuracy without the need for user recalibration.
AMPLIFIER OUT from the PGA is digitized by an A/D Converter whose output becomes a precision
digital voltmeter input to the CPU. In order to find the true junction temperature of the field thermocouple,
the offset corresponding to the reference junction temperature is subtracted from the thermocouple input
signal. After performing this operation, the CPU performs a voltage to temperature conversion, including
linearization, by accessing the appropriate thermocouple table. The most popular thermocouple curves are
stored in CPU ROM as lookup tables. The computed temperature data is transmitted over the IOBUS via
the IOBUS Modem.
4.4 IOBUS MODEM
The IOBUS elements consists of an IOBUS Modem and dual IOBUS Line Drivers/ Receivers. The CPU
supervises IOBUS communications through handshaking operations with the IOBUS Modem. The
IOBUS Modem performs the following:
CConverts received IOBUS data into a format for data-processing.
CConverts digitized field data from the CPU into a format for transmission over the IOBUS to a control
module (e.g., CCM).
4.5 THERMOCOUPLE BURNOUT DETECTION
A Burnout Detection circuit provides for the detection of a failed thermocouple. Under the control of the
CPU, the Burnout Detector alternately outputs +5 and -5 volt pulses into a TC-configured channel as it is
multiplexed. The combination of low thermocouple impedance and input signal filtering averages the +/-5
volts to a very minor ripple on the input signal.
CIRCUIT DESCRIPTION SD39VIM-2
July 19984-4
Should a thermocouple burn out (infinite impedance) or develop a high impedance fault, a significant
ripple voltage would be generated for that channel and detected by the CPU. The action taken by the CPU
depends upon the BURNOUT configuration parameter selected:
CDISABLE: Burn out detection is disabled.
CUP: Burn out detection enabled. Output returned to maximum value.
CDOWN: Burn out detection enabled. Output returned to minimum value.
4.6 CALIBRATOR
Periodically, the CPU turns on the automatic Calibrator circuit. The Calibrator has a precision 5 volt
regulator, the output of which is divided to create a series of precision output voltages. These outputs
(CAL OUT) are signal input references against which the A/D Converter is software calibrated.
4.7 VIM REDUNDANCY
VIM redundancy is accomplished by rack-to-rack type redundancy through pairs of duplicate racks of I/O
and control modules that share a common I/O termination such as the VIM Marshalled Termination
Assembly.
In a redundant pair of racks, the VIM that is in the verify mode is identified by a solid green OK LED and
a black (OFF) ACTIVE LED. A solid green ACTIVE LED indicates an enabled module.
4.8 VIM DIAGNOSTICS
Part of the VIM program includes the execution of diagnostics that can detect hardware errors. Errors are
annunciated by LEDs located on the front bezel of the VIM. The OK LED is the principal error
annunciator. The green ACTIVE LED lights if the module is enabled. A redundant VIM in the verify
mode will show a solid green OK and black (OFF) ACTIVE LEDs.
At initial turn on, the VIM’s CPU uses a common start up routine to perform certain self-diagnostics such
as ROM and RAM tests and to setup specific board functions. If the common start up routine is
successful, the OK LED will be set to a solid green and the VIM begins to execute common I/O board
diagnostics; if not successful, the OK LED will be set to a flashing red color at a 1 second flash rate. 4-
mation software provides additional diagnostic and status displays.
