n NEMA 4X enclosure: Protects against outer corrosive material and incidental contact.
n Isolated inputs: Accepts floating or grounded signals of 0-10VDC or 4-20mA for controlling the speed of the
motor. 3% linearity, through 60:1 speed range, 1% through 30:1 speed range.
n Speed range and regulation: 1% regulation over 60:1 speed range.
n User adjustable calibration pots: IR compensation, min speed, max speed, current limit, input signal min
and signal max.
n Diagnostic: LED for Power On light on front of enclosure.
n Spade and screw terminals: Quick and easy wire terminations.
n Mounted Operators: Power on/off switch, speed potentiometer and signal/manual mode switch.
n Additional features: Dual voltage AC input, AC line fuses, attached heatsink and DC field voltage for shunt
wound motors.
The PCM23400A Series of full-wave rectified SCR drives are a cost-
effective solution for variable speed, process control applications
requiring protection from washdown, dirt, and other corrosive ele-
ments. The PCM23411A and PCM23401A accept 115 or 230 VAC
for control of 90 or 180 VDC, SCR brush-type motors respectively,
ranging from 1/20 to 2 Hp.
For added versatility, these drives have integrated isolation which
allows them to follow analog current or voltage signals from external
devices as a reference for motor speed control. Users can operate
the drive in three distinct modes. 1) manual mode-normal poten-
tiometer operation, 2) signal mode-accepts an external speed refer-
ence voltage or 3) signal with ratioing mode-accepts an external
speed reference voltage that can then be scaled by an external
potentiometer. The wiring configuration of a quick connector inside
the case determines the operation mode. The face of a NEMA 4X
enclosure has a power switch and light, manual/signal input switch,
and external speed potentiometer.
*Some applications may require shunt resistor. Please consult manual for sizing information.
