Product Overview
The Allen-Bradley 1771-ICD is a Series B digital DC input module in the 1771 PLC-5 I/O platform. It provides sixteen sinking-type discrete inputs (20 to 60 V DC) via the 1771 I/O chassis backplane. The module monitors on/off field devices (e.g. dry-contact switches, pushbuttons, sensors), filters input noise, and communicates status to the PLC. Typical uses include machine control panels, industrial discrete signal monitoring, and legacy PLC-5 installations. 1771-ICD is designed for integration within the PLC-5 architecture.
