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 voltage-free 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 connecting block.
The response to a temperature jump depends
on the probe design. As a rule, this device is few times
faster than the inner-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’s ingress protection is IP 20.
Due to low
ingress protection the device is not suitable for using
in dusty rooms or rooms exposed to water ingress.
Connection mode:
For the procedure for connecting wires to the connecting
block refer to Annex 4.
