10.5.3 24 V voltage supply
The voltage of 24 V can be supplied with or without electrical isolation to the
I/O terminals of the XM control.
The same external power supply unit has to supply the 24 V voltage supply of
the XM control and the extension modules. Connect the voltage supply to the
XD1 plugs of the XM control and then bridge the cables to the power connectors
XD1 of the extension modules.
Dimensioning the voltage supply
Observe the maximum currents when dimensioning the voltage supply. A voltage
between 20.4 V and 28.8 V has to be applied directly at the device.
This voltage range also has to be maintained if:
there are variations in line voltage, e.g. caused by different loads of the mains
●
there are varying load states, such as short-circuit, normal load, lamp load or
●
no load
The maximum conductor cross section for the voltage supply is 1.5 mm
