Two-channel binary-input
thermometer for external probes
This model can measure up to two temperature
values, which are sensed by outdoor Pt1000/0 series
probes. In addition, it is provided with two binary inputs
for monitoring voltage-signal changes or changes
of a signal coming from a dry contact. The binary input
changes are registered immediately, irrespectively of
the recording interval setting. To safe record the input
status, the signal must be present for at least 1 s. Binary
inputs of this device are not able to capture
connected/disconnected voltage status. Input signals
are connected to a pluggable terminal block.
The response to a temperature change depends
on the probe design. As a rule, this device is few times
faster than the internal-sensor model. The maximum
length of the probe line wire should not exceed 15 m;
the maximum length of the binary-input cable should not
exceed 30 m. It is recommended to use shielded cables.
The device has not a protection against the ingress of
water or dust. Do not use device at places where such
conditions can be expected.
Connection:
The procedure for connecting the wires to the terminals
can be found in
Annex 4 .
