Allen Bradley 1734-IE4C , it is an Input Module from the Allen-Bradley 1734 Point I/O series.
the 1734-IE4C is an analog input module that provides four channels of current input. It supports a range of current input signals, including 0-20 mA, 4-20 mA, and -20 to +20 mA. The module communicates with the PLC over an industrial communication network, such as EtherNet/IP or ControlNet.
To use the 1734-IE4C module, you would need a compatible PLC, a power supply, and the appropriate communication network. The PLC would handle the overall control and processing of the system, while the input module would provide the analog input signals from field devices, such as sensors or transducers. the 1734-IE4C module is just one component of a larger automation system, and a complete control solution would require additional hardware and software components.
