Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1771-IMD is a digital AC/DC input module from the Allen-Bradley PLC-5 1771 family. It provides 16 field-wiring inputs for monitoring industrial devices using nominal 220 V AC (50/60 Hz) or 220 V DC signals. The module installs into a 1771 B-Series I/O chassis, communicates input status via the backplane to the processor, and includes front-panel LED indicators for diagnostics. It is suited to legacy PLC-5 control systems requiring isolated high-voltage discrete input interfaces. Part number 1771-IMD is referenced throughout.
Best Suited For
- Legacy PLC-5 systems requiring 220 V AC/DC discrete input monitoring
- High-voltage discrete signal interfacing (e.g. limit switches, selectors)
- Retrofit or refurbishment of existing 1771-B chassis installations
- Applications needing per-channel LED status indication
