The supply voltage of the PCD1 / PCD2 automation system is generally used to sup -
ply the PCD2.T500 Module. However, if preferred an external power source can also
be used to supply the module and / or actuators. The following demands are placed
on the supply voltage:

24 V
DC
±20 % smoothed or

19 V
AC
±15 % with full-wave rectifier and smoothing capacitor 10 000 µF / 40 V
