TM150 temperature sensor module (option G51)
4.11.21.1
Description
Terminal Module TM150 is used for sensing and evaluating several temperature sensors.
The temperature is measured in a temperature range from -99 °C to +250 °C for the
following temperature sensors:
● PT100 (with monitoring for wire breakage and short-circuit)
● PT1000 (with monitoring for wire breakage and short-circuit)
● KTY84 (with monitoring for wire breakage and short-circuit)
● PTC (with short-circuit monitoring)
● Bimetallic NC contact (without monitoring)
For the temperature sensor inputs, for each terminal block the evaluation can be
parameterized for 1x2-wire, 2x2-wire, 3-wire or 4-wire. There is no galvanic isolation in the
TM150.
A maximum of 12 temperature sensors can be connected at the TM150 Terminal Module.
