24 Ch , Discrete I/O (0 to 60 VDC, 500 mA/Ch.)
DT1 - North Atlantic Industries (NAI)
The DT1 module features 24 programmable channels for either input (voltage or contact sensing with programmable, on-module pull-up/pull down current sources), or output (current source, sink, or push-pull) up to 500 mA per channel from an applied, external 3 – 60 VCC source. These modules can sense broken input connections and whether an input is shorted to +VCC or to ground.
