The M-7017C is an 8-channel current input module that is specifically designed to measure current only. Its user-friendly design saves both time and effort when measuring a current thanks to a built-in resistor, meaning that you can now measure current directly without adding an external resistor. The M-7017C supports Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the I-7017C.
