1794-OA8I Channel-to-Channel Isolated AC Output Module for Multi-Phase Distributed Control Systems

The Allen-Bradley 1794-OA8I is a FLEX I/O digital AC output module with channel-to-channel isolation. It helps avoid issues between separate AC sources and reduces the risk of faults caused by shared common connections in multi-phase equipment.

Engineer's Note: The 2.25 mA off-state leakage current can keep low-power LEDs partially on. Add a parallel resistor if your load draws under 5.0 mA to prevent faint LED glowing.

Project Case: Deployed in process systems to control valves across separate AC busbars, successfully preventing voltage backfeeding on a single layout.
