Automation stations – Saia PCD2
Saia PCD2.M5xxx controllers
Due to its flat housing design, the Saia PCD2.M5xxx is especially suitable for space-saving applications.
The powerful CPU enables the control and regulation functions of complex applications with up to 1,023
central data points. The PCD2 can be expanded by means of plug-in memory modules to become a
L
on
IP® or BACnet®-enabled controller. The PCD2 has communication interfaces such as USB, Ethernet,
RS-485 and Automation Server On-Board.
System properties
Up to 15 communication interfaces (RS-232, RS-485, etc.)
8 I/O slots that can be expanded by means of module holders
to max. 64 slots (1,023 central data points)
Local I/O expansion with RIO-PCD3.T66x (Ethernet) or
PCD3.T760 (Profi-S-IO)
1 MByte of program memory
