When selecting I/O cassettes, ensure that the internal 5 V and +V supply is not

overloaded.

Detailed information on planning combined PCD2/PCD3 systems can be found in the

PCD3 manual 26/789.

3.6.3 Expansion with PCD4 components

Starting from a PCD2.M120/M150/M170/M480, the PCD4.C225 coupling bus module

makes it possible to run the following I/O modules and manual control modules from

the PCD4 series:

Digital input/output modules Manual control modules

PCD4.E11x PCD4.A810

PCD4.E60 PCD4.A820

PCD4.A200

PCD4.A250

PCD4.A350

PCD4.A400

PCD4.A410

PCD4.B90x

Any PCD4 I/O modules not listed are not supported.

As shown in the illustration below, the PCD4.C225 is connected to the PCD2 via a

PCD2.K100/K110/K120 extension cable.

Using standard PCD4.C220 or PCD4.C260 bus modules, up to 6 additional module

sockets can be attached to the right-hand side of the PCD4.C225 coupling bus

module (making a total of 8 PCD4 sockets).

It is necessary to ensure that the internal 5 V and +V supply for the PCD2 is not

overloaded. The power consumption for the PCD4 modules can be found in manual

26/734.
