Datalogger with 3 inputs 0 - 10 V
and 1 binary input
This model is used to measure up to three voltage inputs
0
– 10 V DC while allowing one binary input to be
monitored. The voltage inputs are not galvanically
isolated from one another. This means that the negative
terminals ("-") are connected to each other. These facts
must be taken into consideration when designing the
device into the circuit. Incorrect connection may cause
degradation of the measured values. Binary input
serves to monitor voltage signals or signals 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 input can capture
connected/disconnected voltage status.
Input signals are connected to a pluggable terminal
block. The
device’s ingress protection is IP 20. Due to
its low ingress protection the device is not suitable for
using in dusty rooms or rooms exposed to water
ingress. The maximum length of the input wires should
not exceed 30 m. It is recommended to use shielded
cables. The battery in the device cannot be charged.
Connection:
The procedure for connecting the wires to the terminals
can be found in
Annex 4 .
