Analogue output
All measured values except real and reactive work, can
be given out as a current via the analogue output. One
internal and six external analogue outputs can be pro-
grammed at maximum.
The external analogue outputs are controlled via a bus
coupling and analogue output clamps of the company
WAG O . The connection of the UMG 503 to the bus
coupling is carried out via the RS232 or RS485 interface.
Both devices, UMG503 and bus coupling, must be con-
nected to each other via the same interface. Each analogue
output can be assigned to
one measured value,
one scale starting value and
one scale end value
Only the internal analogue output in the UMG 503 can
be switched between
0-20mA and
4-20mA
additionally. For the external analogue outputs analogue
output clamps with the signal types
0-20mA,
4-20mA and
+-10V
are available.
Internal analogue output (Option)
For the operation of the internal analogue output an
external auxiliary voltage from 20V up to 30V DC is
required. The connectable maximum load is 500Ohm. If
the analogue output is loaded with a higher resistance,
the output range (20mA) is limited.
internal analogue output
Attention!
The internal analogue output can be used only,
if the option "analogue output" is released.
