Supply (external and internal)
Supply voltage 24 VDC -20...+25% smoothed or
19 VAC±15%full-waverectied(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congurator”fromthePG52.0whichautomaticallycalculatestheinternalpower
consumption of the modules.
Atmospheric conditions
Ambient temperature When mounted on vertical surface with vertically aligned
terminals: 0...+55 °C
In all other mounting positions, a reduced temperature range of
0..+40 °C applies
Storage temperature -25...+85 °C

Test voltage 350 V / 50 Hz AC for nominal unit voltage 24 VDC
Electromagnetic compatibility
Electrostatic discharge according to EN61000-4-2: 8 kV: contact discharge
Electromagneticelds accordingtoEN61000-4-3:eldintensity10V/m,
80...1000 MHz
Bursts according to EN61000-4-4: 4 kV on DC supply lines, 4 kV on
I/O signal lines, 1 kV on interface lines
Noise emission accordingtoEN61,000-4-6:ClassA(forindustrialareas).
