Product Description

The 1769-IF8 is a high-density analog input module designed for the Allen-Bradley Compact I/O platform, fully compatible with CompactLogix and MicroLogix 1500 controllers. It features eight differential or single-ended input channels, enabling the precise acquisition of process variables such as pressure, temperature, and flow rate from industrial transmitters.

Engineered with a Delta-Sigma converter architecture, the 1769-IF8 provides 16-bit unipolar resolution, ensuring high-fidelity signal conversion for sensitive automation tasks. Its design allows for flexible field wiring configurations and seamless integration into Rockwell Automation's programming environment, making it a standard choice for systems requiring high channel counts within a minimal panel footprint.
