PHD-22HT-*1*1
Overview
Isolated safety barrier at detection side: PHD-22HT-*1*1, thermocouple signal input, dual input and dual output.The safety barrier can realize the conversion of thermocouple signal input in dangerous area into 4~20mA signal output and transmit it to safe area. The circuit has two thermocouple inputs and two DC signal 4~20mA outputs.
The output 4~20mA signal can be intelligently configured, and the actual measuring range can be set by computer.
PHD-22HT-*1*1, "*" indicates the input type of thermocouple, please use code to indicate it. This product needs independent power supply.

Example: when the input are 2 inputs with
K-couple, temperature range is 0~1200℃, 2 outputs are 4~20mA, power supply 20~35VDC, then the model should be
PHD-22HT-1111 (0~1200℃).
The measuring range can be set to the specified 0~1200℃ range by computer
