The Allen-Bradley 1746-IA16 is a 16-point AC digital input module designed for use with the SLC 500 programmable logic controller (PLC) system. This module provides a reliable interface between field-side AC input devices and the processor, converting high-voltage AC signals into logic-level signals compatible with the SLC 500 backplane. It is engineered for industrial environments requiring consistent monitoring of AC-powered sensors, switches, and pushbuttons.
Features
16 isolated input points for flexible wiring and signal segregation.
Operating voltage range of 85-132 VAC at 47-63 Hz.
Designed for seamless integration into the SLC 500 I/O chassis.
Status indicators on the front panel for real-time monitoring of input signal states.
Robust construction suitable for standard industrial control cabinets.
Applications
This module is typically utilized in manufacturing and process control systems where AC-based field devices are present. Common applications include monitoring limit switches, proximity sensors, and operator interface buttons within an SLC 500 control architecture.
