Automation stations – Saia PCD2
Saia PCD2.M5xxx controllers
Due to its flat housing design, the Saia PCD2.M5xxx is ideal for space-saving applications.
The powerful CPU enables the control and regulation functions of complex applications with up
to 1023 central data points. This allows the PCD2 to be expanded for L
on
IP® or BACnet®-compatible
controller using plug-in memory modules. The PCD2 has communication interfaces such as USB,
Ethernet, RS-485 and onboard Automation Server.
System properties
Up to 15 communication interfaces (RS-232, RS-485, etc.)
8 I/O slots that can be expanded using module holders
to max. 64 slots (1023 central data points)
Remote I/O expansion with RIO PCD3.T66x (Ethernet) or
PCD3.T760 (Profi S-IO)
1 MB of program memory
