Allen Bradley 1794-IF2XOF2I Flex I/O Isolated Analog I/O Module

Allen Bradley 1794-IF2XOF2I Flex I/O Isolated Analog I/O Module

The Allen Bradley 1794-IF2XOF2I, also cataloged as the 1794-IF2XOF2I Flex I/O Isolated Analog I/O Module, operates as a dedicated hardware component for isolated analog signal acquisition and output execution within the Allen Bradley Flex I/O 1794 system.

Hardware Specifications

EtherNet/IP Deterministic Networks and I/O Density Scaling

The 1794-IF2XOF2I integrates isolated analog input and output channels within the Flex I/O 1794 distributed I/O architecture. The module performs analog-to-digital and digital-to-analog conversion using sigma delta conversion technology. I/O density scaling is achieved through the modular FlexBus structure, allowing combined analog signal processing and remote I/O expansion within a common platform.

Frequently Asked Questions (FAQ)

Q: How many analog channels are available on the 1794-IF2XOF2I?
A: The module provides two isolated analog inputs and two isolated analog outputs.

Q: What conversion method is used by the analog input section?
A: The analog input section uses sigma delta conversion with 16-bit resolution.

Q: Does the module provide channel isolation?
A: Yes. The input and output channels are specified as isolated analog channels.

Field Installation Guidelines

Install the 1794-IF2XOF2I on a compatible DIN rail assembly within the Flex I/O 1794 system. Confirm correct module seating and FlexBus connection before applying field power.

Route analog signal wiring separately from high voltage and switching conductors. Use shielded instrumentation cable where required by the installation environment and terminate shields according to the control cabinet grounding design.

Verify input and output terminal assignments before commissioning. Confirm the external 24 VDC supply wiring polarity and ensure the module remains within the specified environmental conditions provided by the system design.
