Product Introduction
The Allen-Bradley 1746-OX8 is a Digital Contact Output Module designed for the SLC 500 programmable controller family. This module provides eight normally open relay contact outputs, each individually isolated for high-current switching applications. As a key component in industrial automation, the 1746-OX8 handles demanding loads with robust construction and proven reliability.
Industry Applications
Factory Automation: The 1746-OX8 controls motors, solenoids, and valves in manufacturing lines, providing isolated switching that protects sensitive control logic.
Process Control: In chemical or water treatment plants, the module actuates pumps and actuators where isolation and high inrush current handling are critical.
Material Handling: Conveyor systems and sorting equipment benefit from the module’s ability to switch multiple high-current loads without interference between channels.
Installation & Setup Guidance
Mount the Allen-Bradley 1746-OX8 module in any SLC 500 chassis slot. Ensure power is completely removed from the chassis before insertion or removal. The module requires no field wiring; connect outputs via the terminal block. Follow standard safety practices for relay circuits, including proper fuse protection per load specifications.
Maintenance & Reliability
Periodically inspect the 1746-OX8 for signs of wear on relay contacts, especially in high-cycle applications. Clean the module and chassis with a dry, low-pressure air stream to remove dust. The module operates reliably in ambient temperatures from 0 to 60°C, but avoid condensing humidity. Regular checks of backplane connectivity can prevent intermittent faults.
Selection Guide & Purchasing Advice
Before purchasing, verify that your SLC 500 system has an available slot and compatible backplane power capacity. The 1746-OX8 is a direct replacement for earlier output modules.
