The Saia PCD1 systems are the smallest programmable Saia PCD® controllers in a flat design. Along with the standard communication interfaces, integrated data memory and web/IT functionality, all controllers also have at least 18 integrated I/Os. The PCD1 controllers
are ideally suited to small-scale automation tasks, whose challenges and tasks can be successfully processed by the powerful CPU. The many communication options are another advantage: Ethernet TCP/IP, USB port, the onboard RS-485 interface and the expansion
options with BACnet® or LON IP, for instance, are a small sample of the performance capability of PCD1.

Types
- PCD1.M2160 with Ethernet TCP/IP and expanded memory
- PCD1.M2120 with Ethernet TCP/IP
- PCD1.M2020 without Ethernet TCP/IP
- PCD1.M2110R1 with Ethernet TCP/IP for room automation applications
