Allen Bradley 1746-IB32 Digital I/O Modules

Description

The Allen-Bradley 1746-IB32 is a 32-channel sinking DC input module for the SLC 500 programmable controller series. 1746-IB32 Digital I/O Modules operates at a nominal 24V DC, with a voltage range of 15-30V DC, and is designed to interface with binary field devices such as switches, sensors, and auxiliary contacts. Allen Bradley Digital I/O Modules installs into any slot (except slot 0) of a 1746 chassis, supports local or remote I/O configurations, and features a removable terminal block for easy wiring and maintenance.

Features

Electrical Specifications: Allen Bradley Digital I/O Modules Nominal 24V DC operation (15-30V DC range); 5.1 mA typical input current @ 24V DC.

Isolation: Provides 1500V AC isolation for 60 seconds between the backplane and I/O circuits.

Signal Performance: ON state minimum voltage of 15V DC; OFF state maximum voltage drop of 5V DC with a maximum leakage current of 1.5 mA.

Application

Connecting discrete field devices (e.g., push buttons, limit switches, proximity sensors, photocells) to an SLC 500 control system.

Expanding the digital input capacity of SLC 500 systems in local, expansion, or remote I/O chassis configurations.

Allen Bradley Digital I/O Modules Applications requiring reliable binary signal acquisition in industrial automation environments such as manufacturing, material handling, and process control.
