MP-Bus with PCD2.T500

The supply voltage of the PCD1 / PCD2 automation system is generally used to supply

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 VDC ±20 % smoothed or

^ 19 VAC ±15 % with full-wave rectifier and smoothing capacitor 10 000 μF / 40 V
