General technical details
Supply (external and internal)
Supply voltage
24 V
DC
-20...+25% smoothed or
19 V
AC
±15% full-wave rectified (18V DC)
Power consumption
1)
typically 15 W
Capacity of internal
5 V bus
2)
1,400 mA
Capacity of internal
+V bus (16...24 V)
2)
The capacity of the +V bus depends on the capacity of the 5V
bus, as follows (the more precisely the 24 V are maintained, the
higher the possible capacity):
24 V
24 V
24 V
1) The loads handled by the outputs and other consumers are generally more important for sizing the supply than
the internal power consumption of the PCD2.M5.
2) When planning PCD2 systems, it is essential to check that the two internal supplies are not overloaded. This
check is especially important when using analogue, counter and positioning modules, as these may have a very
large power consumption.
It is advisable to use the “device configurator” from the PG5 2.0 which automatically calculates the internal power
consumption of the modules.
