A-B 1746-NI4
The Allen-Bradley 1746-NI4 module is an analog input module for Rockwell Automation’s SLC 500 series PLC. It is mainly used to convert analog signals (such as voltage and current) from the field into digital signals that can be recognized by the PLC. These analog signals usually come from sensors, such as temperature sensors, pressure sensors, etc.
Main function
Analog signal acquisition: Four single-terminal voltage or current analog input signals are collected.
Signal conversion: the analog signal is converted to digital signal, which is convenient for PLC processing.
Modular design: Can be flexibly added to the SLC 500 rack.
