Siemens PXC3.E... Room automation stations CM1N9203en_08
Smart Infrastructure 2020-10-30
Use
PXC3 series room automation stations can be used for buildings with more
sophisticated requirements on functionality and flexibility.
Desigo Room Automation is used when several disciplines (HVAC, lighting,
shading) are combined to form one solution and when high flexibility is required.
Desigo Room Automation is perfect for solutions optimizing energy (class A)
without loss of comfort.
Functions
A PXC3 series room automation station can assume control for multiple rooms.
These programmable room automation stations provide the infrastructure to
provide and process system- and application-specific functions.

Total number of data point used by TX-I/O, KNX PL-Link and DALI.
For details see Desigo Technical principles CM110664, chapter 18.
3)
For commercially available DALI -ballasts up to 64 DALI addresses are
supported.
4)
For commercially available DALI-2 input devices up to 63 DALI-2 addresses are
supported.
Note! The current consumption of the connected DALI ballasts and input
devices must not exceed the guaranteed bus supply current of the PCX3.
The DALI bus power supply may limit number of connectable DALI devices.
