Temperature measurement via TM150 (option G51)

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 can be combined into three groups and evaluated

PTC, KTY84, bimetallic NC contact, PT100 and PT1000 temperature sensors can be

connected and evaluated. 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 strips X531 to X536 according to the

following table.

The TM150 temperature inputs are not electrically isolated.
