Description

The Allen-Bradley 1746-OV8 is a high-performance digital DC output module designed for integration within the SLC 500 programmable controller system. This module provides eight sinking outputs, specifically engineered to manage 24V to 48V DC field devices. By controlling the negative side of the load circuit, the 1746-OV8 effectively bridges the load to the DC common upon activation, providing reliable switching for industrial automation tasks.

Features

Eight (8) independent sinking output channels.
Optimized for high-speed switching with an ON-signal delay of 0.1 ms.
Wide operating voltage range of 10–50V DC.
Designed for compatibility with the Allen-Bradley SLC 500 backplane.
Robust construction suitable for demanding industrial environments.

Installation Guidelines

Ensure power is disconnected from the SLC 500 chassis before inserting or removing the module.
Install the module into a standard SLC 500 I/O slot, ensuring the backplane connector is fully seated.
Verify that field wiring is properly routed to prevent signal interference and maintain clear airflow for cooling.
Follow standard ESD (Electrostatic Discharge) mitigation practices during handling to prevent damage to sensitive internal components.
Confirm that all field devices connected to the sinking outputs are compatible with the 10–50V DC range.

Compliance and Certifications

The 1746-OV8 module is rated for use in hazardous locations, carrying Class I, Division 2 certification for Groups A, B, C, and D. It also complies with UL, C-UL, CE, and C-Tick regulatory standards for global industrial deployment.

FAQ

What is the primary function of the 1746-OV8?

The 1746-OV8 is a digital DC output module that provides 8 sinking channels to control external field devices by switching the negative side of the circuit in an SLC 500 system.
