Limit values/impulse output:
Of
each of the measured or calculated network parameters limit values can be monitored.
These limit values can be assigned to both of the switched outputs.
One or both of the limit value outputs can optionally be set as impulse output. Then a chain of
impulses with the impulse ratio being proportional to the active energy is sent to the output.
Communication interface (optional):
The MFA 2001 can be optionally equipped with a
n
RS-485 Interface. Alternatively a Profibus DP
communication interface is available.
Analogue output (optional):
Any of the measured or calculated network parameters can be assigned to the analogue output.
With this option external logging or
running
secondary control loops is possible.
The output is a current output freely programmable from 0 ... 20 mA or 4 ... 20 mA.
