General supply
Use a power supply without fall-back characteristic curve (see Section “Sizing of the power supply” on page 37).
24 V main supply U
M
Connection technology Spring-cage terminal blocks
Nominal value 24 V DC
Tolerance -15%/+20% (according to EN 61131-2)
Ripple ±5%
Current consumption at nominal voltage (typical) 6 mA + 7 mA for each input set
Current consumption at nominal voltage (maximum) 8 A DC
Continuation Through potential routing
Protective measures
Surge voltage Input protective diodes (can be destroyed by permanent overload)
Pulse loads up to 1500 W are short circuited by the input protective diode.
Polarity reversal Parallel diodes for protection against polarity reversal; in the event of an error
the high current flowing through the diodes causes the fuse connected up-
stream to blow.
NOTE:
Provide external protection for the 24 V area. The power supply unit must be able to supply 4 times (400%) the nominal current of the external
fuse, to ensure that the fuse blows safely in the event of an error.
