Analogue outputs
Source, destination and scale
The UMG505 has 4 analogue outputs. The
analogue outputs have a common earth and are
separated galvanically against the other inputs and
outputs of the UMG 505. For the operation of the
analogue outputs, an external auxiliary voltage of
20V to 30V DC is required.
The maximum burden may not exceed 360 Ohm. If
the analogue output is loaded by a bigger
resistance, the output range (20mA) is limited.
To each analogue output, a range of 4-20mA or 0-
20mA can be assigned.
The following sources can be used for the analogue
outputs:
- Measured values,
- The internal EMAX analogue outputs 1-4 and
- Values, which are transmitted to UMG 505 via
Modbus.
Only measured values, which are configured for the
measured values indication, can be given out by the
analogue outputs. The measured values of real
energy and reactive energy cannot be given out by
the analogue outputs.
