Terminal Module 150

The Terminal Module 150 (TM150) has 6x 4-pole terminals for temperature sensors.
Temperature sensors can be connected in a 1x2, 1x3 or 1x4-wire system. In a 2x2-wire
system, up to 12 input channels can be evaluated. 12 input channels can be evaluated in the
factory setting. The temperature channels of a TM150 can be subdivided into 3 groups and
evaluated together.
The TM150 can acquire the signals from KTY84, PTC, bimetallic NC contact, PT100 and
PT1000 temperature sensors and evaluate them. The fault and/or alarm thresholds of the
temperature values can be set from -99 °C up to 251°C. The temperature sensors are
connected at terminal strip X531 to X536 according to the following table.
The TM150 temperature inputs are not electrically isolated.
You can find additional information in the function diagrams 9625, 9626 and 9627 in the
SINAMICS S120/S150 List Manual.
Selecting the sensor types
● p4100[0...11] sets the sensor type for the respective temperature channel.
● r4105[0...11] indicates the actual value of the temperature channel.

evaluation.
– If the temperature actual value is lower than the rated response temperature, then
r4105[0...3] is set to -50 °C.
– If the temperature actual value is higher than the rated response temperature, then
r4105[0...3] is set to 250 °C.
– If no sensor has been selected or if the temperature actual value is invalid, then
r4105[0...3] is set to -300 °C.
– For switching temperature sensors, such as e.g. PTC and bimetallic NC contact,
symbolically two limit values are displayed:
– r4105[0...11] = -50°C: The temperature actual value is below the rated response
temperature.
– r4105[0...11] = +250°C: The temperature actual value is above the rated response
temperature.
NOTICE
For PTC and bimetallic NC contact the following applies:
What is shown in r4105[0...11] does not correspond to the actual temperature value.
