Temperature measurement via TM150 (option G51)
9.5.6.1
Description
The Terminal Module 150 (TM150) has 6 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. 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 -99 °C to 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.
