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 "Conversion of the valve zone").

12.2.4 Electrical supply plate

The electrical supply plate (35) is connected to a supply board. It can feed in an
extra 24 V power supply for all valves located to the right of the electrical supply
plate via an integrated 4-pin M12 connection. The electrical supply plate moni-
tors 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.
Please see Table 16 for the pin assignments of the M12 plug on the electrical
u
supply plate.

Pin X1S plug
Pin 1 nc (not connected)
Pin 2 24 V DC actuator voltage (UA)
Pin 3 nc (not connected)
Pin 4 0 V DC actuator voltage (UA)
• 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.
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.
