Terminal Module 120

If the temperature sensors in the installed motors do not have protective separation, then
you require a Terminal Module 120 (TM120). Up to four different temperature sensors can
be connected to the TM120. The TM120 senses the actual temperature values and
evaluates them. The fault and alarm thresholds (p4102) of the actual temperature values can
be set from -48° C up to 251° C. Temperature sensors are connected at the TM120 at
terminal strip X521 according to the table above.
You will find additional information in the SINAMICS S120 Control Units and Supplementary
System Components Manual.

– If the temperature actual value is less than the nominal response temperature, then -
50°C is displayed.
– If the temperature actual value is higher than the nominal response temperature, then
250 °C is displayed.
– If the actual temperature value is invalid (F35920 initiated), then -300°C is displayed.
– If p4100 = 0, -300°C is displayed.
– The actual temperature value of the temperature evaluation
– -300 °C if no sensor has been selected or the temperature actual value is invalid
