Automation stations – the basics
Saia PCDs combine PLC functionality with innovative web and IT technology in an industrial quality system.
The basic equation Saia PCD® = PLC + (web + IT) means that the conventional automation pyramid is becoming an open,
transparent structure.
The service life of Saia PCD®: Compatibility and portability guaranteed for all device types across generations.
The Saia PCD® system with its open technology stands for total transparency, combinability and openness. This applies between all the
levels of the automation pyramid, the automation world and the actual operating environment of the user. To achieve this, all Saia PCD®
control and regulation devices generally include comprehensive web + IT functions. These functions do not require additional hardware
and form an integral part of every device. Machines and systems can therefore be very easily integrated into the existing IT infrastruc-
ture.
We develop our products to provide customers with direct added value that enables them to generate sustainable revenue. This
requires products with a long service life and flawless and reliable operation. Previously installed products must always be able to adapt
to changing needs. Existing investments should not always be made obsolete by unwanted, forced innovations and incompatibilities.
This is why we attach such great importance to PLC-based technology with its sustained customer benefit and ease of upgrade. Our
company has remained true to these values for over 50 years. Moreover, we only use components that comply with industrial standards
and which have a service life of at least 20 years.
