Siemens PXC3.E... Room automation stations CM1N9203en_08
Smart Infrastructure 2020-10-30
· The room automation stations have a 2-port Ethernet switch to support for low-
cost cabling via line topology.
· A USB Device port is available for service and commissioning.
· TX-I/O modules connected directly to the PXC3 allow for direct connection of
field devices. This offers maximum flexibility.
· The KNX PL-Link peripheral bus supports room operator units, sensors, and
actuating devices. Selected Siemens field devices to the KNX PL-Link bus
(devices with the KNX PL-Link logo) can be connected.
The KNX PL-Link bus supports integration of commercially available devices
with KNX S-Mode (requires ETS engineering).
· The DALI bus supports lighting control. Commercially available DALI ballasts as
well as DALI-2 input devices can be connected.
Equipment combinations
Depending on the type, PXC3 series room automation stations can be operated
with TX-I/O devices and devices with KNX PL-Link.
