Allen-Bradley 1794-OW8 Relay Output Module

The Allen-Bradley 1794-OW8 Relay Output Module is an eight-channel discrete relay output block for FLEX I/O systems, designed to switch field devices such as solenoids, lamps, and actuators in automation circuits. It interfaces with FLEX I/O controllers and provides eight relay outputs capable of handling AC and DC loads, typically up to 2 A per contact. The module features optical isolation between logic and field circuits, supports DIN rail or chassis mounting (system dependent), and operates in standard industrial temperatures from 0°C to 55°C. Compatible with FLEX I/O networks and Rockwell PLCs including MicroLogix and CompactLogix, it is commonly replaced by Allen-Bradley 1794-OD8 or 1794-OW4, or the Siemens 6ES7 322-1HH01-0AA0.
