Description
Product Description
The Allen-Bradley 1746-OW8 digital relay output module is designed for the SLC 500 programmable controller platform, providing reliable isolated relay switching for industrial control systems. The module features eight normally open relay outputs divided into two isolated groups, with four channels sharing a common terminal per group.
Built for mixed-voltage control environments, the 1746-OW8 supports both AC and DC load switching, making it suitable for motor starters, pilot devices, solenoids, alarms, and interposing relay applications. Its chassis-mounted construction ensures stable installation within SLC 500 racks and control cabinets.
The 1746-OW8 module is commonly deployed in factory automation, material handling systems, packaging equipment, process control panels, and machine automation architectures requiring flexible relay-based output control.
