(cap. 12).
Important:
•
to ensure correct measurements from the probe each wire must be
connected to only one terminal.
•
the two probe wires have no polarity.

T100 temperature probes
For information on the maximum number of probes that can be
connected see the table at the beginning of this paragraph. For details on
the operating range see the Technical Specifications table (see chap. 12).
The probe has three wires: connect one to GND and the other two to two
separate but adjacent universal inputs on the same controller (e.g. U1, U2,
GND, or U4, U5, GND).

onnecting active temperature and humidity probes
For information on the maximum number of probes that can be connected
see the table at the beginning of this paragraph. The number depends on
the power supply used. The distinction is between probes powered by the
controller (teVDC) and probes powered by an external source, and
also between active probes with voltage or current outputs. For details
on the operating range see the data sheets supplied with the probes. The
controller can be connected to all the CAREL DP* series active temperature
and humidity probes configured for 0 to 1 V or 4 to 20 mA.
Note:
in c.pCOmini models it is not possible to manage 0 to 1 Vdc
or 0 to 10 Vdc signals coming from probes powered directy by the
controller.
Important:
for temperature probes use the 4 to 20 mA or NTC
configuration, cause 0 to 1 Vdc signal is limited to the 0 to 1 V range and
is therefore not always compatible with the standard 10 mV/°C signal of
CAREL probes (at temperatures below 0 °C or above 100 °C a probe alarm
may be activated).
