9.2 Digital outputs
The device has 3 digital outputs that
·Are electrically isolated from the analysis
electronics via an optical coupling.
·Have a common reference.
·
Are not
short-circuit proof.
·Require an auxiliary voltage.
·Can be used as pulse outputs.
·Can switch DC and AC loads.
·Can be controlled via Modbus.
·Can emit results from comparators.
CAUTION
Property damage due to connection fault.
The digital outputs are not short circuit proof!
Therefore, connection faults may cause
damage to the connections.
When connecting the outputs, ensure that
the wiring is correct.
CAUTION
Measurement errors when used as a pulse
output.
When using the digital outputs as a pulse
output, measurement errors may occur as
a result of residual current.
For the supply voltage (DC) of the digital
inputs and outputs, use a power adaptor
with a residual current below 5% of the
supply voltage.
NOTE
·Functions for the digital outputs can be
easily and clearly configured in the GridVis®
software (see www.janitza.de).
·A connection between the device and the
PC is required via an interfaces for use of the
GridVis software®.

MID
:
·The function “MID active energy” is assigned
to digital output 1 (terminal 21/22) of the
UMG 96-PA
MID
. The function “MID active
energy” is allocated to Digital output 1 and
can be neither modified nor configured
otherwise!

9.3 LED status bar
The LED status bar on the rear of the device
shows the different input and output states.
DFiFtal Fnputs
Each LED assigned to the input is illuminated
in green if a signal of at least 4 mA flow at this
interface.
DFiFtal outputs
Each LED assigned to the input is illuminated in
green if the output is set as active - irrespective
of any additional connection to this interface.
