Saia-Burgess

Flat construction Saia PCD1 | Saia PCD2 device series

Continuity, originality and individual profile for over 30 years

Flat construction

Controllers with a flat construction traditionally form a main element of Saia® control technology. This design was selected, developed and introduced deliberately as an alternative to cassette/rack construction. It has brought us decades of success in the marketplace, enjoying continuous growth thanks to constant advances and innovations.

The existing main device series are theSaia® PCD1 and Saia® PCD2. Both can be fitted with front-mounting operation/display modules (PCD7.D16x). The PCD1 has 4 slots for interface modules, enabling it to be expanded to 64 I/Os. The PCD2 CPUs offer 8 slots and can be expanded with extension housings to 1024 central I/Os.

Patented housing technology

The patented housing technology of the PCD1/PCD2 series is completly screwless. With regard to mechanical, thermal and electrical robustness, the PCD1/PCD2 series beats many of the apparently heavy-duty designs available on the market. EMC standards are met to an extent that far exceeds CE standards. The high demands of ship approvals are
also demonstrably met. Even in armoured vehicles and trains, many hundreds of standard version PCD2s are in use.

Performance of the flat Saia®  PCD

The performance spectrum of the flat Saia PCD series for communication (at one computing speed)
is enormous. PLC speed extends to the same class as a Siemens S7 318/414 CPU. Even the ‘small’ PCD1 is
available with 3 serial ports + Ethernet-TCP/IP. Plug-in communications modules allow the PCD2 to
be expanded to 9 serial ports, without changing the size of housing. In the newer CPUs, many ports
(such as RS232, RS485, Profibus, USB) already form part of the base CPU.
