AB 1794-IF8IH Flex I/O module

AB 1794-IF8IH

The AB 1794-IF8IH module is a Flex I/O module manufactured by Rockwell Automation (Allen-Bradley) for analog signal acquisition. It has 8 analog input channels, each of which supports the HART protocol and can be connected to HART smart meters. The module is usually installed in a PLC system and is used to collect process variable data, such as temperature, pressure, flow, etc.

In simple terms, this module is like a “sensor collector”, which is able to convert analog signals (such as voltage signals generated by temperature sensors) into digital signals, which are then transmitted to the PLC for processing.

Main function
