IN32: 32 Channel Binary Input Card

The IN32 card has thirty-two inputs, each on a 3-pin header. The other two pins on the 3-pin header are tied to screw terminals. All input are 5 Volt tolerant and space is provided to attach pull-up or pull-down resistor packs.

 

Features: - Thirty-two binary inputs - 3.3 or 5 Volt input - Optional pull-up or pull-down resistors - Convenient screw terminal connections - Uses the ESPI 7474 circuit for reliable operation
