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. Up to 12 input

channels can be evaluated in a 2x2-wire system. Twelve (12) input channels can be

evaluated in the factory setting. The temperature channels can be combined into as many as

3 groups and evaluated together.

Temperature sensors of type PTC, KTY84, bimetallic NC contact, PT100, and PT1000 can

be connected and evaluated. The fault and alarm thresholds of the temperature values can

be set from -146.2 °F (-99 °C) to +483.8 °F (+251 °C).

The temperature sensors are connected to terminal strips X531 to X536 according to the

following table.

The temperature inputs of the TM150 are not electrically isolated.
