
DC current in the range of 0 to 20 mA
Range:
(0 to 20) mA DC
Accuracy:
± 20 uA
Resolution:
better than 0.1 uA *)
Input impedance
approximately 100 Ω
Minimum allowable input current:
0 mA (disconnected circuit)
Maximum allowable input current:

*) to achieve this value, the corresponding number of
decimals must be set
The Multilogger does not contains the power
supply suitable for passive transmiters with a
current loop. This situation has to be resolved by
additional power supply source.

Binary signal - monitoring changes of the binary
signal. You can connect a contact, voltage signal or
open connector transistor. The binary input can be
used on inputs No. 3 and 4 only.
Input voltage for level “switched on”:
< 0.4 V
_________________________________________________________________________________
The binary input will not work correctly if the source has
a high impedance at its “switched on” state. The problem
can be solved by connecting an external resistor of an
impedance of approximately (1 to 10) kΩ connected in
parallel to the input.
Input voltage for level “switched off”:
> 2 V
Minimum input voltage:
0 V
Maximum input voltage:
+30 V DC
