Product Description P/N: 1794-OB8EP
Description
The Allen-Bradley 1794-OB8EP is an 8-point FLEX I/O digital output module providing sourcing outputs for 24 VDC control applications. Each channel supports up to 2 A of output current with low on-state voltage drop and minimal off-state leakage. The module includes electronic protection that disconnects output channels under fault conditions, improving system safety and reliability.

Information About 1794-OB8EP
The 1794-OB8EP is part of the FLEX I/O family and provides eight electronically protected sourcing outputs for distributed automation systems. Its design allows for module insertion and removal under power because field wiring is terminated at the terminal base rather than the module itself. The unit operates over a wide 19.2–31.2 VDC supply range and supports fast on/off switching times suitable for motion-related and general-purpose control tasks. Compatible with multiple terminal base types, the module integrates into FLEX I/O networks connected through EtherNet/IP, ControlNet, DeviceNet, or Universal Remote I/O adapters.
Key Features:
- Eight Sourcing Outputs: Supports 24 VDC output switching for a variety of field devices.
- Electronic Protection (EP): Automatically disconnects outputs during faults to prevent damage.
- 2 A per Channel Capability: Handles higher current loads with a 10 A per module maximum.
- Hot-Swap Installation: Modules can be replaced under power since wiring remains with the terminal base.
- Low Voltage Drop: Maximum 0.2 VDC on-state drop for efficient load operation.
- Wide Supply Range: Operates from 19.2–31.2 VDC with minimal ripple requirements.
- FLEX I/O Platform Compatibility: Works with terminal bases such as 1794-TB2, -TB3, -TB3S, -TBN, and -TBKD.
- LED Diagnostics: Includes status indicators for channel and module operation.
The 1794-OB8EP delivers the reliability and precision required for protected DC output control in FLEX I/O distributed automation systems.
