PHD-22HZ-*1*1
Overview
PHD-22HZ-*1*1, RTD signal input, dual input, and dual output constitute the isolated safety barrier.
The isolated safety barrier has the ability to transmit the 4/20mA signal output that is produced from the RTD input signal in the hazardous area to the safe area. The circuit has two RTD signal inputs and a DC double output.
The 4–20 mA output signal can be set up wisely. A computer can be used to set the real range of RTD.
PHD-22HZ-*1*1, where "*" denotes the RTD input type; please use the code to specify.
This product requires a separate power source.
