Connections of Temperature Sensors and Cables
Connections of Temperature Sensors Directly to the Device
It is possible in principle to connect temperature sensors with 2-phase or 3-phase technology. To achieve the
specified accuracy, Siemens recommends only using 3-phase technology.

Terminal) to Terminals M1 to M5
²
For a connection with 2-phase technology, you must connect a bridge, for example for RTD 2, between
M3 and M4.
