Product Description
1794-OA8I Channel-to-Channel Isolated AC Output Module for Multi-Phase Distributed Control Systems
Allen-Bradley 1794-OA8I FLEX I/O digital AC output module
Product Overview

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.

Key Specifications
8 Isolated Channels: Connects different AC phases to one module, saving external relay costs.
120V AC, 0.5A Per Channel: Safely drives industrial AC contactor coils directly.
Live Swapping (RIUP): Replaces hardware without system shutdown, preventing production downtime.
Technical Insights

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.

Frequently asked questions about 1794-OA8I module
Frequently Asked Questions
What is the Allen-Bradley 1794-OA8I?
A FLEX I/O 8 point AC output module. The 1794-OA8I is used for 120V AC control signals and isolated output applications.
Why does channel isolation of 1794-OA8I matter?
Each output channel works separately. Useful when different AC sources are connected in the same control cabinet.
Which terminal base fits this 1794-OA8I?
1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBN and 1794-TBNF. Many users select 1794-TBNF when fuse protection is needed.
Can 1794-OA8I be replaced under power?
Yes. RIUP is supported, so the module can be removed and installed while the FLEX I/O system stays running.
What should I know about leakage current of 1794-OA8I?
Maximum off-state leakage is 2.25 mA. Small LED indicators may need an external resistor.
