13. 13 Analog output
The device has 1 passive analog output,
which can output a maximum current of 0 -
20 mA.
An external 24 V DC power adapter is re-
quired for operation.

Fig.: Principle of the analog output with
voltage monitoring
The analog output can be configured in a
user-friendly way via the GridVis® software.
To do this, enter the assigned measurement
value, the initial and final value and the output
range in "
Periphery ."

500 W
Initial value
1000 W
Final value
• If the effective power is 500 W, a current of
4 mA is outputted via the analog output. At
an effective power of 1000 W, the output is
20 mA.
The measured effective power is directly
proportional to the current of the analog
output.
