Applications
A comprehensive block library for room automation is provided as part the scope of delivery. The library contains predefined application functions for room climate, lighting, shading, and superimposed room functions. The applications can be combined with operating and display functions as required. The individual application functions can be adapted to customer needs and are programmable. The application functions do not depend on the selected field devices.
See Application Catalog.
Configuration of application functions
Many application functions are preconfigured and available in the library. Retroactive configuration during engineering or commissioning is possible. Your own configured application functions and entire rooms can be stored in a project library.
Configuration of field devices
The application architecture does not depend on the field device interface. Field devices can be connected directly to the PXC3 room automation station (via TX-I/O modules) or via bus (KNX or DALI) or IP communication.
Many field devices are preconfigured and available in the library. Retroactive configuration during engineering or commissioning is possible. Project-specific field devices configured accordingly can be saved in a project library.
Modular room automation stations
PXC3 room automation stations with control functions for one or multiple rooms:
- Assume control functions for one or multiple rooms.
- Communicate with each other or other system components via BACnet/IP. Scope and functionality of supported BACnet objects are matched to the requirements of room automation.
- Provide a 2-port Ethernet interface for cost-effective cabling via daisy chaining.
- Contain bus supplies for island bus, KNX PL-Link, and DALI. Internal bus supplies can be extended for island bus and KNX PL-Link as needed.
- Have an integrated web server for IP communication with touch room operator units.

TX-I/O modules
TX-I/O modules (TXM1) help connect field devices to the PXC3 room automation station. Bus supply and interface modules (TXS1, TXA1) are available as an accessory.
The following TX-I/O modules can be used with the PXC3 room automation station:
- TXM1.8T: Triac module with 8 outputs (AC 24 V) to control thermal and motorized valve actuators (AC 24 V) for up to 4 actuators (3-point output) or 8 actuators (permanent contact or pulse width modulation).
- TXM1.6RL: Bistable relay module to switch lighting for up to 6 data points.
- TXM1.8RB: Relay module to control blind motors for up to 2 motors (3 end switches) or 4 motors (2 end switches).
- TXM1.16D: Digital input modules for up to 16 data points.
- TXM1.8D: Digital input modules for up to 8 data points.
- TXM1.6R: Relay module for up to 6 data points.
- TXM1.8U: Universal module for up to 8 data points.
