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 three 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 isolated.
Note
Fault messages
Fault messages for an individual temperature channel in the TM150 are propagated to all
other drive objects connected with the TM150.
As such all other drive objects (connected with the TM150) also trigger a fault.
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.
Note
For PTC and bimetallic NC contact the following applies:
What is shown in r4105[0...11] does not correspond to the actual temperature value.

– For switching temperature sensors, such as PTC and bimetallic NC contact, two limit
values are displayed symbolically:
– r4105[0...11] = -50° C: The actual temperature value is below the rated response
temperature.
– r4105[0...11] = +250° C: The actual temperature value is above the rated response
temperature.
