CR Series
Modulated Amplifier Modules for "100 Series" Sensors
CR Series MAXI-AMPs combine power supply, modulated photo-
electric amplifier, timing logic (in CR5 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 substantial
amount of panel space. Several models are available, for either 120V
or 240V ac operation, and either with or without timing logic. Alte-
natively, any model may be powered by 12 to 28V dc.
CR Series modules are specifically designed for use with the popular
"100 Series" of Banner miniature sensors (page 3). Their rugged en-
capsulated design, slim ribbon-style connecting cables, and small size
make these sensors ideal for use in many situations previously considered
impractical or impossible. MAXI-AMP modules themselves are also
ruggedly built for dependable industrial duty.
CR Series MAXI-AMP modules contain the state-of-the-art Banner
custom-designed CMOS modulator/demodulator/amplifier circuit, of-
fering high immunity to both ambient light and electrical interference
plus reliable sensor performance. All models have Banner's exclusive,
patented Alignment Indicating Device (AID™) system, which lights an
LED indicator whenever the sensor sees a "light" condition, and pulses
the LED at a rate proportional to the received light signal strength.
All CR Series modules are programmable for LIGHT or DARK operate
and either high or low hysteresis. Input response time may be set at
0.3, 2, or 10 milliseconds. The 10-millisecond response mode offers
enhanced immunity to electrical interference ("noise"), and also mini-
mizes optical "crosstalk" between adjacent sensors.
CR5 models include a versatile multi-function timing logic circuit which
is programmable for 12 of the most popular and useful delay, one-shot,
and latch functions. Each timing function has a choice of three time
ranges. Timing and sensitivity adjustments are accomplished via rugged
15-turn potentiometers for very accurate settings. CR Series circuitry
is designed to prevent false outputs on system power-up.
The output circuit for all CR Series modules is an SPDT 5-amp electro-
mechanical relay. Additionally, CR3 models have an NPN transistor
solid-state switch. The output may be programmed for either normally
open or normally closed operation. A solid-state relay is offered as an
option to the electromechanical relay (see below).
An auxiliary input is available on CR5 models for interrogation or reset
of the selected logic function (see example, page 4). Page 6 describes
the function of the auxiliary input for each logic mode. A dc power
supply is included for powering an additional self-contained dc sen-
sor.

CR 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). The other
solid-state contact will switch dc loads of up to 30V dc and up to 50 milliamps.
Both contacts are isolated from the MAXI-AMP power supply.
