Power supply unit

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 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.
The connection for the actuator voltage is an M12 plug, male, 4-pin, A-coded.
Please see Table 23 for the pin assignments of the M12 plug on the electrical 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.

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 connections. They come together to form the "backplane", which the bus coupler uses
to control the valves.
