Siemens PXC00-U Programmable Automation Station

Siemens PXC00-U is a Desigo PX modular automation station that serves as the field controller for building services within Siemens’ Desigo PX automation ecosystem. It supports up to 64 TX/I/O data points (load units) and uses P-bus and PPS2 connections for scalable I/O expansion, with the PXA30-RS module available to extend its connectivity. The unit is designed for 24 V AC operation and is intended for DIN-rail mounting in a cabinet or equipment rack, enabling compact integration into commercial HVAC installations, and it is freely programmable using PPCL with a Web interface for configuration. As part of the Desigo PX family, PXC00-U interoperates with other PX controllers to deliver a modular, scalable automation solution for heating, ventilation, and building management tasks.
