PHD-12TZ-*11
Overview
Isolated safety barrier: PHD-12TZ-*11, RTD signal input, single 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 dual output.
The output 4-20mA signal, can be intelligently configured. The actual range of RTD can be set by computer.
PHD-12TZ-*11, "*" indicates the input type of RTD, please use the code to indicate.
This product needs an external 20~35VDC power supply.
