24 V Bus Terminal Supply
Connection
Through 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
Special demands on the voltage supply
The bus terminal supply U
BK
is electrically
isolated from U
M
/U
S
when it is supplied
separately. This is only possible when using two
separate power supply units.
Nominal value
24 V DC
Tolerance
-15%/+20% (according to EN 61131-2)
Ripple
±5%
Permissible range
19.2 V to 30 V
Minimum current consumption at nominal voltage 0.10 A DC
(At no-load operation, i.e., incoming remote bus
connected, no local bus devices are connected,
bus inactive)
Maximum current consumption at nominal voltage 1.25 A DC
Consisting of:
0.75 A DC for communications power
0.5 A DC for analog voltage supply
Safety measures
Only for the bus terminal supply
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.
