Overview
The thermal resistance input temperature converter can isolate and convert the thermal resistance (RTD) signal to output a 1:1 correspond signal and a 4~20mA signal for driving the load. Intelligent configuration is possible, and the actual range of the thermal resistance can be set through computer software.
This product requires independent power supply, and the power supply, input and output are isolated.

Schematic diagram
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, terminals 5 and 6 must be short circuited
