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. This
device is 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.
