Overview
RTD input temperature transmitter can isolate and convert the thermal resistor (RTD) signal into a DC signal, which is used to drive the load. Intelligent configuration is possible, and the actual range of the thermal resistance can be set through computer software. It has the function of disconnection alarm and out-of-range alarm function.
This product needs to be powered independently, and the power supply, input and output terminals are isolated.

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(2 and 3) must be short circuited
