Banner MAXI-AMP Series - Manual (Page 10)

CM Series MAXI-AMPs combine power supply, modulated photo-
electric amplifier, timing logic (in CM5 models) and output relay in a
single compact, cost-saving module. CM-series modules work to-
gether with the popular family of Banner high-performance modulated
remote sensors (pages 13-17). These sensors offer small size and
excellent optical performance, and are built to operate in highly
demanding sensing environments. MAXI-AMP modules themselves
are also ruggedly built for dependable industrial duty.
CM 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 CM 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
minimizes optical "crosstalk" between adjacent sensors. Unlike other
amplifier designs, input response time settings of the CM Series
modules do not affect sensor range.

The amount of amplification available from CM Series MAXI-AMP
modules is too high to operate with the Banner SP100 Series of
miniature modulated remote sensors. CR Series modules correct this
incompatibility with a modified modulated amplifier design. CR Series
specifications are exactly the same as for the standard CM Series
models (listed above) except for the difference in amplifier gain.
Available models are listed in the table at the right.
SP100 Series sensors are ideal for OEM machinery and for tight spaces
where the use of photoelectric sensors was previously considered
impossible. The SP100 Series is described in the Banner catalog.
CR Series modules are also available with the solid-state output option
(see above).

CM5 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 (see page 6). Each timing function has a
choice of three time ranges. Timing and sensitivity adjustments are
accomplish-ed via rugged 15-turn potentiometers for very accurate
settings. CM Series circuitry is designed to prevent false outputs on
system power-up.
An auxiliary input is available on CM5 models for interrogation or reset
of the selected logic function (see example, page 17). 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 sensor.
The output circuit for all CM Series modules is an SPDT 5-amp electro-
mechanical relay. Additionally, CM3 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 information below).

CM 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. The contact 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.
