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.

Note: 1. PHD-11TZ - * 1 does not include output part 2
2. The power rail function is an optional function, and users need to specify the power supply method when placing an order
The selection of power rail connectors can refer to page 89 of the "Annex"
3. When inputting a three wire RTD, it is necessary to ensure that the three wires are of equal length as much as possible
4. When inputting a two-wire RTD, safety barrier terminals 4 and 2 must be short circuited
