Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1746-OA8 is an Allen-Bradley SLC 500 series discrete AC output module that provides eight triac output channels arranged as two groups of four. It installs in a standard SLC 500 chassis slot (not slot 0) and is used to switch AC loads within industrial control systems, typically in packaging, material handling, motor control, and machine automation applications. Each channel supports control of 100-240 VAC loads, allowing localized AC switching within an SLC control architecture. Part number 1746-OA8.
Best Suited For
- Switching AC loads (100-240 VAC) within SLC 500 systems
- Applications requiring group-based triac outputs
- Control of resistive loads such as solenoids or heaters
- Retrofit or maintenance of legacy SLC 500 installations
