Digital Inputs
The UMG505 has 20 internal inputs. On the internal
inputs 1 to 4, the 4 optical inputs (
digital inputs 1-4)
are handled. On the internal inputs 5 to 12 the 8
inputs of the LON-Bus interface (Option), and on the
internal inputs 13 to 20 the 8 inputs of the MODBUS
interface (Option) are handled.
The
condition
of the digital inputs
digital input 1-4
can be called up via the serial interfaces (Option).
Each of the 20 internal inputs can be assigned to
one of the 16 input channels.
Each input channel can simultaneously
Changeover an energy meter,
Effect the Emax reset,
Synchronize the internal clock and
Select another target value for Emax pro-
gram.
Two digital inputs (
digital inputs) can be combined
by
AND
and the result can be assigned to an input
channel. In this case, both digital inputs must be
active to activate the assigned input channel.
Each of the
digital Inputs 1-4 is assigned to an event
counter. The deletion of the event counters is done
together with the real energy meters.
If a function except pulse valence is assigned to a
digital input 1-4, all changes of the input are saved
with date and time.

Digital input 4
Digital input 4 can be used as
pulse input
for real
energy measurement. For this purpose, a pulse
valence must be assigned to the
digital input 4 in
menu „S0 input“. If the pulse valence was assigned
to the
digital input 4, the changes of the input are
not registered in the event memory.
