3.4.4 Expansion housings
The PCD2.C2000/C1000 expansion housing provides space for 8/4 additional I/O
modules and can be expanded to provide up to 64 sockets. The dimensions of the
housing match those of the PCD2.M5_ base unit. The sockets are numbered clock-
wise from the left, from 0 to 7. The expansion housings with sockets 8 to 15 etc. are
also numbered clockwise. They are connected to each other and to the base unit with
26-wire expansion cables or connectors:

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 calculation table at
