12.2 Valve Zone
The following figures show the components as illustrations and sym-
bols. The symbol representations are used in section
sion of the Valve
Zone.
12.2.1 Base plates
The valves from the AV series are always mounted on base plates that are assem-
bled into blocks so that the supply pressure is applied to all valves.
The base plates are always 2x or 3x base plates for two or three single or double
solenoid valves.

12.2.2 Transition plate
The transition plate (29) has the sole function of mechanically connecting the bus
coupler to the valve zone. It is always located between the bus coupler and the
first pneumatic supply plate.

12.2.3 Pneumatic supply plate
Pneumatic supply plates (30) can be used to divide the valve system into sections
with different pressure zones, see section

12.2.4 Electrical supply plate
The electrical supply plate (35) is connected to a supply board.
The board can feed in 10% for all valves via an integrated 4-pin M12 connection
and an extra 24 V power supply. These valves are located to the right of the elec-
trical supply plate.
The electrical supply plate monitors the additional power supply (UA) for low
voltage.

The tightening torque of the M4x0.7 ground screw (WS 7) is 1.25 Nm +0.25.
Pin assignments of the M12 plug
The connection for the actuator voltage is an M12 plug, male, 4-pin, A-coded.

• The voltage tolerance for the actuator voltage is 24 V DC ±10%.
• The maximum current is 2 A.
• The voltage is internally isolated from UL.
12.2.5 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.
Zone.
The base plates' block assembly also ensures that the valve driver boards are con-
nected via electrical plug connections. They come together to form the "back-
plane", which the bus coupler uses to control the valves.
