24 V Main Supply/24 V Segment Supply
Connection
Through power connector
For terminal point assignment see page 3
Connection method
Spring-clamp terminals
Recommended cable lengths
30 m (98.43 ft.), maximum; do not route cable
through outdoor areas
Voltage continuation
Through potential routing

if they are supplied
separately. This is only possible when using two
separate power supply units.
Behavior if voltage dips and interrupts occur
Voltages (main and segment supply) that are
transferred from the bus terminal to the potential
jumpers follow the supply voltages without delay.
Nominal value
24 V DC
Tolerance
-15%/+20% (according to EN 61131-2)
Ripple
±5%
Permissible range
19.2 V to 30 V
Current carrying capacity
8 A, maximum
Safety measures
Surge voltage
Yes
Polarity reversal
Yes
Provide an external fuse for the 24 V area
This 24 V area must be fused externally. The power supply unit must be able to supply 4
times the nominal current of the external fuse, to ensure that the fuse blows safely in the
event of an error.
