When dimensioning the power supply, the maximum currents are to be taken
into account, see VDE 0100-523. Directly at the device, there must be a
voltage of 19.2 to 30.0 V.
The voltage must also be retained in the case of
D fluctuations in the mains voltage, e. g. caused by varying loads on the
power supply.
D different load states, e.g. short-circuit, normal load, lamp load or idling.
The maximum cable cross-section for the power supply of the IO-BOX32 is
2
1.5 mm
.
The IO-BOX32 logic supply can bridge voltage drops of up to
10 milliseconds to ensure the continuity of its operation.
A master switch complying with VDE 0100 must be fitted for the IO-BOX32,
sensors and actuators.
