5 Outputs and Inputs
5.1 Analog Outputs
The CT has two analog output channels.
With the CT 4M the outputs are freely
selectable.
5.1.1 Output channel 1
This output is used for the object temperature. The selection of the output signal can be done via the
programming keys [►6 Operating]. The software allows the programming of output channel 1 as an alarm
output.

5.1.2 Output channel 2 [LT/ G5/ P3/ P7 only]
The connection pin OUT-AMB is used for output of the head temperature [-20-180 °C or -20-250 °C (on
LT02H and LT10H) as 0–5 V or 0–10 V signal]. The software allows the programming of output channel 2
as an alarm output. Instead of the head temperature T

also the object temperature T

or electronic box
temperature T

can be selected as alarm source.
According to the chosen output signal different
connection pins on the mainboard are used
(OUT-mV/mA or OUT-TC).
CAUTION: Please do never connect a supply voltage to the
analog outputs as this will destroy the output.
The CT is not a 2-wire sensor!
