Description

The Allen-Bradley 1746-IC16 is a 16-point digital input module designed for use within the SLC 500 programmable logic controller system. This module provides a reliable interface for monitoring 48V AC/DC digital signals from field devices, such as limit switches, pushbuttons, and proximity sensors, converting them into logic-level signals for the processor.

Features

• 16 discrete input points for high-density signal monitoring.
• Compatible with the Allen-Bradley SLC 500 I/O chassis.
• Designed for 48V AC/DC input signal voltage levels.
• Status indicators for each input channel to facilitate quick troubleshooting and diagnostic monitoring.
• Robust industrial design suitable for standard control cabinet environments.

Applications

This module is commonly utilized in industrial automation applications requiring the integration of 48V signal levels into an SLC 500 control architecture. It is suitable for manufacturing, material handling, and process control systems where discrete signal acquisition is required.
