13.10.3 Analogue output (AO) characteristics
The analogue outputs are active, that is, they have their own power supply, and they must
not
be connected to an external supply.
Using a configured or selected output curve, the controller converts the regulation output or operating data to the corresponding
current (-25 to 25 mA) or voltage (-10 to 10 V).

Using an analogue output with a switchboard instrument
The analogue output can be connected directly to a 4 to 20 mA switchboard instrument.
13.10.4 Pulse width modulation (PWM) output characteristics
The pulse width modulation (PWM) output is a regulation output for low power circuits. It may be used to regulate an electronic
engine, but not an actuator.
