38 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.

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.

Pressure regulators for pressure zone control and single pressure con-
trol do not differ in terms of the electronic control. This is why the dif-
ferences between the two AV-EP pressure regulators are not discussed
in further detail here. The pneumatic functions are described in the op-
erating instructions for AV-EP pressure regulators, which can be found
on CD R412018133.

35 Short bridge card
Bridge cards have the sole function of bridging the pressure supply areas. They
are therefore not taken into account during PLC configuration.
Bridge cards are available in long and short versions:
The long bridge card is always located directly on the bus coupler. It bridges the
transition plate and the first pneumatic supply plate.
The short bridge card is used to bridge additional pneumatic supply plates.

12.2.8 UA-OFF monitoring board

The UA-OFF monitoring board is an alternative to the short bridge card in the
pneumatic supply plate. See g Fig. 24).
The electrical UA-OFF monitoring board monitors the actuator voltage UA for sta-
tus UA < UA-OFF. All voltages are passed through directly. The UA-OFF monitor-
ing board must therefore always be installed after an electrical supply plate to be
monitored.
