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
Analog signal acquisition: collect 8 analog signals and convert them into digital signals.
HART protocol support: Support HART protocol, can communicate with HART intelligent instrument, obtain instrument configuration information and diagnostic information.
Isolation protection: Provides isolation between channels to prevent signal interference.
Flexible configuration: Software can be flexibly configured to meet different application requirements.
