PHG-12TZ-466+
Overview
The thermistor input temperature converter with surge protection function can convert the Pt100 signals of two wire and three wire thermistors (RTDs) into a 1:1 signal of the thermistor. It can be intelligently configured, and the actual range of the thermal resistance can be set through computer software.
This product requires independent power supply, with isolated power supply, input, and output terminals.

Note:
1. 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"
2. When inputting a three wire RTD, it is necessary to ensure that the three wires are of equal length as much as possible
3. When inputting a two-wire RTD, safety barrier terminals 5 and 6 must be short circuited
