Outputs and Inputs
8.1
Analog Outputs
The thermoMETER CT has one or two analog output channels.
Please do never connect a supply voltage to the analog outputs. The thermoMETER CT is not a 2-wire sen-
sor!

8.1.1
Output Channel 1
This output is used for the object temperature. The selection of the output signal can be done via the pro-
gramming keys
The CompactConnect software allows the programming of output channel 1 as an
alarm output.

According to the chosen output signal different connection pins on the main board are used
(OUT-mV/mA or OUT-TC).
8.1.2
Output Channel 2 (only CT-SF02, CT-SF15, CT-SF22, CTH, CTP-7 and CTP-3)
The connection pin OUT-AMB is used for output of the sensor temperature [-20 - 180 °C or -20 - 250 °C (on
CTH-SF02 and CTH-SF10) as 0 - 5 V or 0 - 10 V signal]. The CompactConnect software allows the program-
ming of output channel 2 as an alarm output. Instead of the sensor temperature THead also the object tem-
perature TObj or controller temperature TBox can be selected as alarm source.
