U5841M, U5841G
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. Unlike
the U0843M (U0843G) model, this input can capture
connected/ disconnected voltage status.
Input signals are connected to a pluggable terminal
block. 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. The maximum
length of the input wires should not exceed 30 m. It is
recommended to use shielded cables.
Connection:
The procedure for connecting the wires to the terminals
can be found in
Annex 4 .
