A-B 1746-NI4

Allen-Bradley 1746-NI4 is an analog input module designed for the SLC 500 series Programmable Logic controllers (PLCS). It can convert analog signals from external devices (such as temperature, pressure, flow, etc.) into digital signals that can be recognized by PLC, so as to realize the acquisition and processing of analog data.
