✤Low power consumption design, low temperature drift, automatic zero calibration.
✤Totally isolated between four channel input signals/communication/power supply
✤Support hot-plug
✤The MODBUS RTU communication protocol is supported, and the communication rate is as high as 115200bps.
✤Support power supply and communication in two ways: backplane mounting rail and terminal.
✤Combined used with PHM-7100 to support MODBUS TCP/IP, so that to simplify the installation and maintenance, and to improve the data transmission performance.
