3.5 Extension with PCD3 components
The PCD3.Mxxxx can be extended with extension module carrier PCD3.Cxxx so
that additional module slots are available (chapter 3.6 Module carrier).
Up to 15 PCD3.Cxxx module carriers with PCD3.K010 connectors and/
or PCD3.K106 or PCD3K116 cables can be connected to the PCD3.Mxxx0
(PCD3.M3020 / 3120 are not expandable). This allows the user to connect a
maximum of 64 I/O modules or 1023 digital inputs/outputs.
