Introduction The PMI-3003 digital input daughter board features high voltage
(>1500 VDC) optical isolation on 24 descrete inputs. The PMI-3003 provides 24 input channels accessible through
one 50 pin flat cable connector. It has on board screw terminals for easy wiring. Optically-isolated signal
conditioning provides isolation between separate channels,
as well as between each channel input and the controller.
A red LED on each input channel indicates its status. If the
input signal is high, the LED is on. You can configure each
channel to work in either isolated or non-isolated mode. A variable resistor adjusts the threshold level for all 24 isolated
input channels simultaneously.
Compatible with all cards with 20pin or 50pin flat connector
