This module accepts 16 inputs, accommodating both AC (120V) and DC (125V) signals. It converts these signals into appropriate logic levels for processing by the PLC. Typical input devices include proximity switches, limit switches, selector switches, float switches, and pushbutton switches. The module features a green "Module Active" indicator and 16 red status indicators for each input point, providing clear visual status of input conditions. It is compatible with 1771 Series B or later I/O chassis, as well as 1771-AM1 and -AM2 chassis.
