NOTE
A four-pole M8 male connector and a
four-pole M8 female connector are used
to connect the supply voltage to the sub-
bus. Use the SUB-IN connection to feed
in the power supply and the SUB-OUT
connection to forward the power further.
The power supply and the analogue
outputs share a common earth and are
not electrically isolated.
The choice of the output signal (current or voltage) is
made by selecting the pins. The current or voltage
range is selected in the configurator of the manufac-
turer of the controls.
