Information About 1794-OW8
The 1794-OW8 is a relay output module in the Allen-Bradley Flex I/O series, built with eight Normally Open electromechanical relays for isolation and dependable load control. It mounts onto compatible terminal bases such as the 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBN, and 1794-TBNF, enabling flexible installation within distributed systems. The module operates from a 24 VDC supply, supports FlexBus communication, and incorporates protective snubber circuitry for stable switching performance. Its rugged design, status indicators, and wide electrical ratings make it suitable for complex automation tasks that require precise relay actuation.
Key Features:
- Eight Isolated Relay Outputs: Provides independent Form A channels for switching AC and DC loads.
- Wide Voltage Ratings: Supports 5–30 VDC and up to 250 VAC resistive loads for versatile integration.
- Flex I/O System Compatibility: Operates with any Flex I/O adapter for distributed control architectures.
- LED Status Indicators: Includes eight yellow indicators for real-time output channel monitoring.
- DIN-Rail Mounting: Installs quickly on standard terminal bases for streamlined panel layouts.
- Low Contact Bounce: 1.2 ms bounce time reduces wear and enhances switching reliability.
- Robust Isolation Design: 250 V continuous isolation improves safety between relays, backplane, and power circuits.
- Industrial Shock and Vibration Ratings: Withstands 30 g shock and 5 g vibration for demanding applications.
The 1794-OW8 delivers the reliability and precision required for dependable relay-based output control in industrial automation systems.
