EtherNet/IP and Flex I/O System Integration
The 1794-OF4I is designed for use within Allen-Bradley Flex I/O architectures using compatible Flex I/O adapters and terminal bases. The module operates as a distributed analog output node where controller data is transferred through the Flex I/O communication structure and converted into isolated field output signals.
The module supports industrial control system expansion through I/O density scaling within the Flex I/O platform. Installation requires compatible terminal base hardware and proper adapter configuration for the selected distributed I/O network.

Q: What is the FlexBus current requirement of this module?
A: The module requires 50 mA FlexBus current within the Flex I/O system.
Field Installation Guidelines
Install the module on a compatible DIN rail assembly with the correct Flex I/O terminal base before applying field wiring. Verify that the 24 VDC external supply wiring matches the module requirements and that power polarity is correct before startup.
Route analog output wiring separately from high-voltage switching conductors to reduce electrical interference. Use appropriate shield termination practices for sensitive analog circuits according to site electrical standards.
Confirm terminal base engagement, adapter communication status, and controller I/O configuration before placing the analog outputs into service. Do not remove or install the module under conditions that exceed the specified operating environment.
