Product Description

Description

The Allen-Bradley 1746-IV8 is a reliable current sourcing DC input module designed specifically for the Allen-Bradley SLC 500 modular hardware platform. This general-purpose module provides dependable discrete input sensing for industrial automation applications, helping to bridge field-level sensor signals with your control architecture. Featuring built-in front-panel LED status indicators for each I/O point, the module allows maintenance technicians to quickly verify point-level operating status at a glance.

Engineered for standard industrial control environments, the 1746-IV8 incorporates convenient self-lifting pressure plate terminals that safely accommodate up to two 14 AWG (2mm square) wires per connection point, reducing installation time and ensuring secure, vibration-resistant wiring. It draws minimal backplane power, making it an efficient choice for expansion racks within existing SLC 500 systems.

Features

Designed for integration within the Allen-Bradley SLC 500 programmable controller system.
Current sourcing (sink/source designation depends on field device configuration; standard DC sink/source terminology applies).
Features front-panel LED status indicators providing real-time visual feedback for each of the input points.
Equipped with self-lifting pressure plate terminals that securely accept up to two 14 AWG wires per connection.
Robust noise rejection and reliable signal delay characteristics for dependable industrial switching.

Applications

Discrete signal monitoring from 24VDC sensors, limit switches, and photoelectric eyes.
Manufacturing assembly lines and automated material handling equipment.
Machine tool control and process skids utilizing SLC 500 architecture.
Retrofitting or expanding legacy Allen-Bradley control systems.

Installation Guidelines

Ensure that all rack power and field power supplies are turned off before installing or removing the 1746-IV8 module. Insert the module firmly into the designated slot of the SLC 500 chassis and secure it using the top and bottom chassis retaining screws. Verify that field wiring is properly stripped and secured under the self-lifting pressure plates without stray wire strands causing short circuits. Power on the system and check that the front-panel indicators respond correctly to input device actuation.
