Product Summary
The 1794-OA8 Flex I/O AC output module delivers eight non-isolated outputs with 120V AC nominal voltage. It handles 4A total current and includes diagnostic capabilities. This module reduces start-up time and simplifies troubleshooting.
Product Procurement & Buyer Guide
Engineers and procurement managers rely on the 1794-OA8 for its robust 120V AC switching that suits standard industrial applications. The module directly installs on terminal base units like 1794-TB3 and mounts on DIN rail without extra hardware. Its output current rating reaches 4.0A at 500mA per channel, supporting typical solenoid valves and contactor coils. The diagnostic capabilities detect I/O field device faults and significantly cut start-up time. This module also draws only 80mA at 5V DC from the FlexBus, permitting dense system configurations with minimal power draw.
Expert Technical Evaluation & Performance Review
The 1794-OA8 exhibits a maximum on-state voltage drop of 1.0V at 0.5A, while off-state leakage stays below 2.25mA, ensuring high isolation. Signal delay measures half a cycle maximum for both ON and OFF transitions, enabling fast response in time-critical processes. Thermal dissipation reaches 14.0 BTU/hr at 0.5A, and you must consider derating at elevated temperatures for sustained performance. The surge current of 7A for 40 milliseconds repeats every 8 seconds, handling transient loads effectively. This engineering provides reliable operation in non-hazardous and Class 1, Division 2 environments.
