Description

The Allen-Bradley 1746-IN16 is a 16-point digital input module designed for use with the SLC 500 programmable logic controller (PLC) system. This module provides 16 discrete inputs, allowing the SLC 500 processor to monitor the status of field devices operating at 24V AC/DC. It serves as a reliable interface between industrial sensors, switches, and the control system, facilitating high-speed data acquisition in automated environments.

Features

  • 16-point digital input configuration.
  • Compatible with 24V AC/DC signal levels.
  • Designed specifically for integration with the Allen-Bradley SLC 500 platform.
  • Compact modular design for efficient rack mounting.
  • Status indicators for real-time monitoring of each input channel.

Applications

This module is widely used in industrial automation applications requiring the monitoring of discrete signals, such as limit switches, pushbuttons, proximity sensors, and relay contacts. It is suitable for manufacturing, material handling, and process control systems that utilize the SLC 500 architecture.
