Valve driver boards

Valve drivers, which establish an electrical connection between the valves and the bus coupler,
are built into the bottom reverse side of the base plates.
The base plates' block assembly also ensures that the valve driver boards are connected via
electrical plug contacts. Together, they form the "backplane", which the bus coupler uses to control
the valves.

Electrical supply plates can be used to separate the valve system into sections with different voltage
zones. For this purpose, the supply board interrupts the 24 V and the 0 V lines from UA voltage in the
backplane. A maximum of ten voltage zones are permitted.
The power supply to the electrical supply plate must be taken into account during PLC
configuration.
