Allen-Bradley 1771-ID16 Isolated Input Module is a 16-channel digital input module for PLC-5 systems that handles 120 V signals. Designed for use in a 1771 I/O chassis, it provides isolated inputs for ON/OFF devices and translates field signals into PLC-5 logic levels. Each of the 16 channels is isolated to protect the controller from field wiring transients. The 1771-ID16 was discontinued by Rockwell on December 31, 2019.
