• PCD1.M2110R1 (PCD1.Room)

  • Central processing units

Saia PCD1.Room (Saia PCD1.M2110R1) is a programmable room controller for sophisticated solutions with many communication options. In addition to the I/Os that are already integrated, the controller offers a free I/O slot for an individual expansion with inputs/outputs or communication options. Web/IT functions for mobile operation, for instance, are also already onboard. Furthermore, Saia PCD1.Room offers various possibilities for integrating other systems in the room through standard communication interfaces. (Energy) efficient and individual room automation can be easily implemented as a result. The controller also provides a good basis for achieving the energy efficiency classes according to EN 15232:2012.
