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.

UA-OFF monitoring board

The UA-OFF monitoring board is an alternative to the short bridge card in the pneumatic supply plate
(see Fig. 15 on page 112).
The electrical UA-OFF monitoring board monitors the actuator voltage UA for status UA < UA-OFF.
All voltages are directly passed through. The UA-OFF monitoring board must therefore always be
installed after an electrical supply plate to be monitored.
In contrast to the bridge card, the UA-OFF monitoring board has to be taken into account when
configuring the control.

Possible combinations of base plates and cards

Valve driver boards, 4x, are always combined with two 2x base plates. Table 20 shows the possible
combinations of base plates, pneumatic supply plates, electrical supply plates, and transition plates
with various valve driver boards, bridge cards, and supply boards.
