CL Series modules are available with a solid-state relay which replaces
the electromechanical relay. This is actually two SPST solid-state
contacts. One contact will switch ac loads, and is rated at 250V ac
maximum and 3/4 amps maximum at 25 degrees C (derated to 1/2 amp
at 50 degrees C). A solid-state contact is particularly helpful when
switching inductive ac loads which can cause electrical "noise" and
contact damage when switched with a "hard" relay contact.
The other solid-state contact will switch dc loads of up to 30V dc and
up to 50 milliamps. Both solid-state outputs are electrically isolated
from the MAXI-AMP power supply. Both outputs switch within the 1
millisecond response time of the CL module circuitry. NOTE: ac loads
may take up to 1/2 cycle (8.3 milliseconds) to turn "off".
Both outputs are normally open, but may be programmed for normally
closed operation.
Except for the output configuration, the specifications for the models
listed in the table at the right are exactly the same as for the standard
CL Series models.

Banner CL Series MAXI-AMP™ modules are the perfect solution
for many sensing/control applications where economy, versatility,
dependability, and ruggedness are important. CL Series MAXI-AMPs
combine power supply, timing logic (in CL5 models) and output relay
in a single compact, cost-saving module. The integrated, stand-alone
design saves both the expense of a separate control chassis and a sub-
stantial amount of panel space. Several models are available, for either
120V ac or 240V ac operation, and either with or without timing logic
(models are listed in table at above right). Alternatively, any model
may be powered by 12 to 28V dc.
The well-defined electrical characteristics of CL Series MAXI-AMP
modules provide a wealth of application possibilities. The input cir-
cuit accepts signals from any Banner dc sensor with an NPN (current
sinking) output; as well as from MAXI-AMP, MICRO-AMP, and
Plug Logic modules. The input is compatible with almost any sensor
or circuit which has an NPN transistor (current sinking) output. Ad-
ditionally, inputs may be generated by limit switches, contact closures,
and optical couplers. A 50mA power supply is included for powering
10 to 30V dc devices.
CL5 models offer a versatile multi-function timing logic circuit which is
programmable for twelve of the most popular and useful delay, one-shot,
and latch functions (see page 5). The MAXI-AMP offers the choice of
either single or dual timing functions in the same module. Logic and
timing may be easily reprogrammed as control requirements change.
In order to allow accurate timing adjustments, each CL5 model has
three time ranges to choose from. Timing adjustments are made via
rugged 15-turn potentiometers. Circuitry is included to prevent any
possibility of false output on power-up.
An auxiliary input is available on CL5 models for interrogation or
reset of the selected logic function by using an additional sensor or
input signal (see example, page 3). Page 5 describes the function of
the auxiliary input for each logic mode.
The output circuit for all CL Series modules is an SPDT 5-amp elec-
tro-mechanical relay. A solid-state relay is offered as an option to the
electromechanical relay (see information below).
Additionally, CL3 models have an NPN transistor solid-state switch.
This solid-state output may be used to take advantage of the amplifier's
fast 1-millisecond response. This output may be connected directly to
the primary or auxiliary input of other Banner logic modules, including
CL5 modules, MICRO-AMP logic modules, and Plug Logic modules.
In addition, this output can interface to other dc devices or circuits
such as counters, rate meters, or programmable controllers. Switching
capacity is 20mA at 12V dc. The output may be programmed for either
normally open or normally closed operation.
Like all MAXI-AMPs, the CL Series modules are designed both
electrically and mechanically for solid dependability in industrial
environments.

This hookup is for DC NPN (current sinking) models of S18 Series, Q25 Series, and
other DC sensors bearing the EZ-BEAM logo.
CL5 model MAXI-AMPs have an auxiliary input at terminal #9 which may
be used for the interrogation or reset of the selected logic function. This is
accomplished by a switch closure between pins #9 and #1 (Common). The
auxiliary input may also be switched by a DC device with an NPN transistor
(current sinking) output. The effect of the auxiliary input is described for
each logic function on page 5.
This example shows a typical inspection/rejection scheme which uses a
Banner MINI-BEAM as the inspection sensor. Typically, the CL5 module
would be programmed for the ONE-SHOT or DELAYED ONE-SHOT logic
function. If the SM312 "sees" an acceptable condition when the SE612 senses
the leading (or trailing) edge of the product, the SM312 will inhibit a reject
pulse from occuring. Reject products will be ejected by the output pulse.
NOTE: the MAXI-AMP can supply 50mA for external 10 to 30V dc devices.
Carefully check the current draw of the devices to be powered by the MAXI-AMP.

WARNING The MAXI-AMP modules described in this data sheet do NOT include the self-checking redundant circuitry neces-
sary to allow their use in personnel safety applications. A failure or malfunction can result in either an energized or a de-energized
output condition.
Never use these products for personnel protection. Their use as safety devices may create an unsafe condition which could lead to seri-
ous injury or death.
Only MACHINE-GUARD and PERIMETER-GUARD Systems, and other systems so designated, are designed to meet OSHA and ANSI machine safety
standards for point-of-operation guarding devices. No other Banner sensors or controls are designed to meet these standards, and they must NOT be used
as sensing devices for personnel protection.

The diagram shows switch locations,
and the table summarizes the program
switch positions.
A group of ten switches located on one side of the module is used to select the timing logic
for CL5 models.
Switches #1 through #7 are used to select the logic function. Switch #8 programs the output
for either NORMALLY OPEN or NORMALLY CLOSED operation. Switches #9 and #10
program the time range(s). There are three ranges: 10 to 150 milliseconds, 0.1 to 1.5 seconds,
and 1 to 15 seconds. The programmed range will be the same for both functions of a dual
timing mode (ON & OFF DELAY, DELAYED ONE-SHOT, and REPEAT CYCLE). However,
DELAY and HOLD times are independently adjustable within the selected range.

Light or Dark Operate LOGIC DESCRIPTION
Hookup of Multiple Self-contained Sensors
Any number of self-contained dc sensors may be wired together
in parallel to a single CL Series MAXI-AMP module to create
almost any multiple-sensor logic configuration. Power for the
sensors may be obtained from MAXI-AMP 400mA power
supply CP12 (shown below) or from 1-amp model PS120-15.
The table at the right describes how the four most frequently
used multiple-sensor logic configurations may be created.
MINI-BEAM SM312 Series and VALU-BEAM SM912 Series
sensors have a switch on the back of their housings which is
used to program the sensors for LIGHT or DARK operate.
MAXI-BEAM sensors are set for LIGHT or DARK operate
using the programming ring. MULTI-BEAM sensors are
programmed for LIGHT or DARK operate with the logic
module jumper wire. OMNI-BEAMs are programmed by a
switch in the sensor block.
For ON/OFF sensor operation, light operate is equated to
normally open output, and dark operate is defined as normally
closed. EZ-BEAM sensors have both a normally open and a
normally closed output. Selection of either output determines
the LIGHT/DARK operate mode. ECONO-BEAM sen-
sors are not programmable and must be ordered for LIGHT
OPERATE (standard models) or DARK OPERATE (model
suffix "NC").
The addition of a jumper wire between MAXI-AMP terminals
#10 and #11 changes the input response from a low-going to a
high-going signal. This feature, combined with the selection
of LIGHT or DARK operate at the sensor, allows "AND" logic
with parallel sensor connections.

LIMIT: The output of the LIMIT function follows the action of the input, as it does with the ON/OFF function. However,
an input signal which is longer than the adjustable LIMIT ("HOLD") time will turn the output "off". Removing the input
signal resets the timer. This function is sometimes called "TIME LIMITED ON/OFF", and is useful for energy conservation.
Grounding pin #9 cancels the output. Lifting the inhibit restarts the LIMIT timer, if an input signal is present.
ON/OFF: ON/OFF operation does not involve timing. The output simply follows the action of the input signal.
Grounding pin #9 (AUXILIARY) turns the output "off", regardless of the state of the input signal. This may be accomplished
by closing a switch or relay contact between pins #9 and #1 (common), or by connecting an open collector NPN (current
sinking) output of any external dc device directly to pin #9. NOTE: connect the COMMON of any external dc device to
pin #1 of the MAXI-AMP to establish a voltage reference between the dc supply for the external device and the internal dc
supply of the MAXI-AMP.
ON DELAY: The ON DELAY timer keeps the output "off" until the selected LIGHT or DARK signal has been pres-
ent for the preset "DELAY" time. If the input signal is interrupted, the timing is reset and starts over with the next signal.
Grounding pin #9 immediately cancels an output in progress and resets the delay timer. The delay timer is restarted when
the inhibit signal is removed, if an input signal is present.
OFF DELAY: The output energizes immediately when the input signal occurs, but does not de-energize until the
signal has been removed for the preset OFF-DELAY ("HOLD") time. Grounding pin #9 prevents an output from occuring.
If an inhibit input occurs during an output, the output remains "on" for the remainder of the OFF-DELAY time.
ON & OFF DELAY: ON and OFF DELAY logic combines both timing functions into a single mode. The ON-
DELAY ("DELAY") time and the OFF-DELAY ("HOLD") time are independently adjustable within the selected time range.
Momentary grounding of pin #9 during the ON-DELAY period resets the DELAY timer. An inhibit signal which occurs
during an output will allow the output to stay energized for the remainder of the OFF-DELAY time. ON and OFF DELAY
logic is often used in jam and void control, high/low level control, and edge-guiding applications.
ONE-SHOT: The output of a ONE-SHOT function is a pulse of adjustable "HOLD" duration which is independent
of the duration of the input signal. With the MAXI-AMP programmed for LIGHT operate, the pulse occurs when the input
signal changes from dark to light. In DARK operate, the pulse occurs with a light to dark input transition. Grounding pin
#9 prevents the one-shot from triggering, but does not affect a pulse already under way.
DELAYED ONE-SHOT: A DELAYED ONE-SHOT is initiated by either a momentary or maintained input
signal. This input starts the adjustable "DELAY" period, after which the output pulses for an adjustable pulse ("HOLD")
time. No further action occurs unless the input is removed and reapplied, beginning a new sequence. Grounding pin #9
during the delay period will cancel the sequence, and no output occurs. This feature is often used for inspection/rejection
control logic. An inhibit signal will not affect a pulse under way.
REPEAT CYCLE: The REPEAT CYCLE function provides an oscillating output when an input signal is present.
Presence of an input signal triggers an adjustable "DELAY" timer. After the delay, the output energizes for an adjustable
"HOLD" period. If the input remains, the output continues to cycle "on" and "off" at this rate indefinitely. When the signal
is removed, any output in progress completes and then remains "off" until the next signal and DELAY period. Grounding
pin #9 cancels the sequence, but will allow the completion of a "HOLD" period in progress. Lifting the inhibit signal begins
the DELAY period, if an input signal is present.
AC LATCH: An AC LATCH is the combination of a ONE-SHOT and a LATCH. A momentary or sustained input
will latch the output "on". Grounding pin #9 will reset the latch, even if the input signal remains. The output will not re-latch
until the input signal is removed and then reapplied.
DC LATCH: The output will latch "on" whenever the selected LIGHT or DARK input condition occurs. Grounding
pin #9 of a dc latch will turn the output "off" regardless of the state of the input signal. If the signal is present when the reset
is removed, the output will immediately latch "on" again.
DELAY AND LATCH: The DELAY + LATCH is a combination of the ON-DELAY and DC LATCH functions.
An input must be present for at least the adjustable "DELAY" time for the output to latch "on". If the input signal is removed
during the timing cycle, the timing is reset. Momentary grounding of pin #9 resets the latch and/or the DELAY timing cycle.
Sustained grounding of pin #9 inhibits any output.
LIMIT AND LATCH: The LIMIT + LATCH operates exactly like the LIMIT function, except that the LIMIT
("HOLD") timer can be reset only by the auxiliary input. An output remains latched "off" until reset by momentarily ground-
ing pin #9. In addition to resetting the timer, grounding pin #9 will hold the output "off", regardless of the state of the
input signal.

Model RS-11 Socket
The RS-11 is supplied with a coding ring and pin (see diagram at right). This allows a MAXI-AMP to be
keyed to fit only its own 11-pin socket. The pin is installed in one of the eleven slots in the RS-11, and
the notch in the ring is aligned to slip over the pin. When the MAXI-AMP is removed from the RS-11,
the coding ring stays with the MAXI-AMP base, while the coding pin remains in the socket.
Model RS-11 is an eleven-pole round-pin screw
terminal relay socket which is used to make electri-
cal connections to any MAXI-AMP module. The
socket provides in-line wire clamp screw terminals
which will accept from one #24 AWG up to two
#14 wires at each pin. The RS-11 is UL recognized
(file #E92191) and CSA approved (file #LR38486).
It may be mounted directly to a panel plate or via
standard 35mm DIN-rail track (see below). A hold-
down wire is supplied with each RS-11 socket (see
dimension diagram on page 2).
