DESCRIPTION

SNAP I/O analog output modules are part of Opto 22’s SNAP PAC

System. They mount on SNAP PAC racks along with other I/O modules

and a SNAP PAC brain or R-series controller.

These software-configurable output modules handle a wide variety of

signal levels. Most provide dual-channel packaging. All SNAP analog

modules are factory calibrated. Part numbers ending in -FM are

Factory Mutual approved.

SNAP analog output modules have an on-board microprocessor to

provide module-level intelligence, which makes them an ideal choice

for Original Equipment Manufacturers (OEMs). For additional

information about the stand-alone operation of SNAP analog

modules, please refer to the SNAP I/O Module Integration Guide

(form 0876).

SNAP racks have a retention rail locking system. Use two 4-40 by

½-inch standard machine screws to hold each module securely in

position on the SNAP rack.

Specifications and wiring diagrams are in module descriptions

starting on page 2. Dimensional drawings begin on page 15.

Notes for legacy hardware: Most SNAP analog output modules can

also be used with legacy SNAP Simple, SNAP Ethernet, and SNAP

Ultimate brains and with serial SNAP brains such as the B3000. These

modules can be mounted on SNAP B-series or M-series racks.

Exceptions are noted in individual module descriptions.

Isolation

All SNAP analog output modules are isolated from all other modules

and from the I/O processor (SNAP PAC brain or on-the-rack controller).

On most dual-channel modules, the two channels are not isolated

from each other. Exceptions: SNAP-AOA-23-iSRC, SNAP-AOD-29, and

SNAP-AOD-29-HFi have two isolated channels.

Transformer isolation prevents ground loop currents from flowing

between field devices and causing noise that produces erroneous

readings. Ground loop currents are caused when two grounded field

devices share a connection, and the ground potential at each device

is different.

Isolation also provides protection for sensitive control electronics from

industrial field signals.

IMPORTANT: Since most SNAP dual-channel analog output modules

provide two single-ended output channels with a common reference,

these dual channels are transformer and optically isolated from other

modules, but not from each other. However, SNAP-AOA-23-iSRC,

SNAP-AOD-29, and SNAP-AOD-29-HFi do have channel-to-channel

isolation.

DUAL-CHANNEL TIME-PROPORTIONAL

OUTPUT VOLTAGE 5–60 VDC

Description

The SNAP-AOD-29 module provides two channels of time-proportional

output (TPO). The outputs are used to switch or control DC loads such

as lamps or indicators, solenoids, relay coils, and PLC logic. Each TPO

channel can switch 0.5 A of load current ranging from 5 VDC to 60

VDC, over a period range of .25 seconds to 64.25 seconds.

Both TPO channels also have individual “inhibit” inputs dedicated to

turning off the output, a useful feature in temperature and interlock

control applications. The channels are optically isolated from each

other.

NOTE: The SNAP-AOD-29 module cannot be used in a SNAP PAC

IO4AB system. Instead, use the built-in TPO functionality available on

all SNAP-PAC brains that support IO4AB.

DUAL-CHANNEL TIME-PROPORTIONAL

OUTPUT VOLTAGE 2.5–24 VDC, 0 TO 100 KHZ

Description

The SNAP-AOD-29-HFi is a TPO (time-proportional output) or PWM

(pulse-width modulation) module that converts an analog value to a

digital on/off output. The outputs are used to switch or control DC

loads such as lamps or indicators, solenoids, relay coils, and PLC logic.

Each channel can switch 100 mA of load current ranging from 2.5 VDC

to 24 VDC supplied externally, over a period range of 0.00001 seconds

to 64.25 seconds.

The two channels are optically isolated from each other.

Five volts through a 200 Ohm pull-up resistor are provided internally

for each channel for use with TTL loads. This feature means you don’t

have to provide the pull-up voltage supply required for each output.

This module requires a SNAP PAC controller or brain with SNAP PAC

firmware version 9.3c or higher. It cannot be used with legacy

controllers or brains.

NOTE: The SNAP-AOD-29-HFi module cannot be used in a SNAP PAC

IO4AB system. Instead, use the built-in TPO functionality available on

all SNAP-PAC brains that support IO4AB.

8-CHANNEL MULTIFUNCTION

VOLTAGE/CURRENT OUTPUT

The SNAP-AOVA-8 is an analog output module with 8 channels,

individually configurable for any one of six voltage or current output

ranges:

Each range has 4096 counts (12 bits) of resolution.

The SNAP-AOVA-8 requires a 24 VDC excitation voltage brought in

through the field connector on the top of the module. This voltage is

internally isolated with transformer and digital data isolators, and then

used to source all channels.

Because all current is sourced from within the module using the 24

VDC excitation, current outputs are self-sourcing and cannot be used

with an external loop supply or in loops that are loop-powered or

have a self-sourcing device in the loop.

Each channel is individually current or voltage limited and not

affected by opens or shorts on adjacent channels. Connect both wires

Specifications:

from the module, so that a change in output on one channel will not

affect another channel.

All negative output terminals on the module are tied together

internally. To prevent ground loops, use loads with isolated signal

inputs or use devices with the same power source, so they have a

common ground.

To wire the module, a 6-foot-long SNAP-HD-20F6 cable is required.

The cable has a 20-pin connector at the module end and flying leads

for wiring to field devices. See wiring information on page 14.

You can also use a SNAP-TEX-32 breakout board for wiring

convenience. See the SNAP TEX Cables & Breakout Boards Data Sheet

(form 1756) for more information.

The SNAP-AOVA-8 requires a SNAP PAC brain or rack-mounted

controller with firmware version R9.4b or higher. It cannot be used

with legacy controllers or brains.
