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 14 for the pin assignments of the M12 plug on the electrical
u
supply plate.

• 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.

Supply board
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 volt-
age zones are permitted.
The power supply to the electrical supply plate must be taken into ac-
count during PLC configuration, because the modules do not occupy I/
O data, but they do occupy group diagnostic bits.
12.2.6 Pressure regulators
You can use electronically operated pressure regulators as a pressure zone con-
trol or single pressure control depending on the selected base plate.
