PHD-12HZ-*11
Overview
Isolated safety barrier: PHD-12HZ-*1, RTD signal input, one input and dual output.
The isolated safety barrier can convert the RTD input signal in hazardous area to 4~20mA signal output and transmit it to the safe area. The circuit is equipped with single RTD signal input and DC signal output.
The output 4~20mA signal, can be intelligently configured. The actual range of RTD can be set by computer.
PHD-12HZ-*1, "*" indicates the input type of RTD, please use the code to indicate. This product needs independent power supply.
