The Allen-Bradley 1794-OA8I is an 8-point isolated AC digital output module for the FLEX I/O system. It provides eight individually isolated output channels for switching 85 to 132 VAC field loads.
Each output is rated for up to 0.5 A at 55 degC. The module supports a maximum combined output current of 4 A when all eight channels operate at 0.5 A.
Channel-to-channel isolation separates the individual AC output circuits. The field circuits are also isolated from the FLEX I/O backplane.
The 1794-OA8I is designed for distributed digital output applications requiring independently isolated 120 VAC load control within a FLEX I/O station.

The 1794-OA8I connects to field devices through a compatible FLEX I/O terminal base arrangement.
Each output channel is electrically isolated. Separate AC sources are required for individual channels where channel-to-channel isolation must be maintained.
Field wiring should follow the applicable Rockwell Automation 1794-OA8I wiring diagram and terminal-base documentation.
Verify the catalog number and 85 to 132 VAC field-load requirement before installation.
Confirm the selected FLEX I/O terminal base and wiring arrangement.
Verify load current remains within the output and module current limits.
Preserve channel isolation where the application requires isolated AC circuits.
Check field wiring before applying AC power to the outputs.
Verify each output independently during commissioning.
Confirm PLC output commands correspond with the intended field loads.
