PCD1 E-Line system overview
The Saia PCD1 E-Line series was specifically developed for installation in
electrical sub-distributors. The compact design enables automation in confined
spaces. The two-wire bus connection between individual modules enables
both centralised and decentralised automation over a distance of up to 1000
m. The modules are designed and produced in accordance with IEC 61131-2
to industrial quality. The extensive programmability and integration of Web+IT
technologies enables effective automation over the entire service life of plants
and properties.
Control system
Visualisation and control of the connected components is an important aspect of automation.
The web server can directly undertake the tasks of the control system for this purpose for small
applications. For more complex projects, data is transferred to a control system via standard
communication protocols such as BACnet. The Saia Visi.Plus® control system is suitable for this.
Controller
The Saia PCD® controller functions as a master for the attached modules. Here it can undertake
more complex controls and form the interface to the control level. The integrated automation
server and the Web+IT functions can be directly used here to visualise the control via a web panel
or browser. Saia PCD® is the ideal interface for other plants thanks to the support of numerous
protocols such as BACnet, L
on
, Modbus, etc.
Programmable I/O modules
The programmable I/O modules of the Saia PCD1 E-Line series with Saia PG5® enable the
autonomous and safe operation of the modules even if communication to the master station is
interrupted.
The local function of a room, for example, is therefore guaranteed at any time. The modules are
programmed with Saia PG5® via the master controller or directly via USB.
I/O modules
The PCD1 E-Line I/O modules enable centralised automation in the control cabinet and the
decentralised distribution of the components through the bus connection. They can be commis-
sioned quickly using the implemented override operation.
Communication modules and gateways
Modules from different manufacturers are integrated into the system via communication mod-
ules. The RS-485 radio gateway allows modules to be connected wirelessly.
