PCD3.W500 module, fully equipped
(with additional module plugged on)
Apart from the bus connector, DC-DC converter and terminals, the base module carries the
two input channels with the 2-pole jumper for unipolar or bipolar operation and a number of
preset potentiometers, which cannot be adjusted by the user.
The plug-on module contains the two analogue outputs with the two 3-pole jumpers for the
individual unipolar or bipolar operation of each output.
The module also works without the plug-on module.
Changing the jumpers
On this circuit board there are components that are sensitive to electrostatic discharges. For
