【详情】：HF6208 in use It receives voltage and current input through AI terminal and reads the current value with Modbus protocol. First, the voltage input value can be read normally, but The current value remains constant at 4mA. It uses a PT sensor and ranges from -100 to 400 degrees. temperature controller The current temperature is 20c, and When the temperature controller output is measured with a m
