Configured for high-voltage and low-voltage load switching in CompactLogix control platforms, the Allen-Bradley 1769-OW8I (1769-OW8I Discrete Output Module) provides direct electrical execution via eight individually isolated normally open relay outputs. The hardware serves as the primary interface for managing diverse field loads across industrial automation networks.

Hardware Specifications

Allen-Bradley Deterministic Network and Control Integration

The 1769-OW8I ensures compatibility with the backplane bus communication velocity of the CompactLogix system, supporting deterministic I/O data exchange. The module facilitates seamless I/O density scaling, allowing for granular control of field devices. Firmware flash compatibility is managed through the primary controller, ensuring that the isolated output states are accurately processed and integrated into the global control logic. This architecture minimizes signal interference between output channels, maintaining operational integrity in high-density automation environments.

Field Installation Guidelines

• Mounting: Secure the module to the CompactLogix DIN rail or panel mounting surface.

• Wiring: Terminate field wiring to the isolated output points, ensuring compliance with wire rating specifications for the intended AC or DC load.

• Grounding: Ensure proper chassis grounding to mitigate electromagnetic interference and maintain electrical safety standards.

• Load Isolation: Verify that load requirements do not exceed the relay contact ratings for the specific application voltage.

Frequently Asked Questions

Q: Are the outputs on the 1769-OW8I galvanically isolated from each other?

A: Yes, the module features eight individually isolated relay outputs, allowing for the switching of different voltage levels or power sources on a per-channel basis.

Q: Does this module support hot-swapping?

A: No, the 1769-OW8I does not support hot-swapping. Power must be removed from the I/O rack before installing or removing the module to prevent electrical damage.

Q: Can the relays switch both AC and DC loads?

A: Yes, the relay outputs are capable of switching loads within the range of 5 to 265 VAC or 5 to 125 VDC.
