Digital Input Modules | Allen-Bradley 1746-IC16 SLC 500
The 1746-IC16 is a 16-point digital input module for Allen-Bradley SLC 500 programmable logic controller (PLC) chassis systems. Operating at a nominal voltage rating of 48 VDC with sinking input circuit topology, this module detects discrete signal states from field devices such as pushbuttons, limit switches, and proximity sensors to interface directly with the host SLC 500 processor backplane.
Functional Operation and System Compatibility
Designed for installation into any open slot of a 1746 chassis, the 1746-IC16 receives external 48 VDC sinking inputs and isolates the field signals from the logic backplane. Signals received by the module are updated continuously to feed status bits into the PLC data table for control program execution.
System Wiring Safety Notice
Always disconnect system power to the SLC 500 chassis and disable field power sources prior to inserting, removing, or wiring the module to prevent electrical shock or hardware damage.
