Extension module PXX-PBUS

Product catalog summary
Overview: The document details the PXX-PBUS extension module used in Siemens' Desigo building automation system. It facilitates the integration of existing PT-I/O modules with Desigo automation stations, specifically PXC50...D, PXC100...D, and PXC200...D models.
Specifications: The PXX-PBUS module serves as a P-bus interface for modular automation stations. It supports all PT-I/O modules and requires a TXS1.12F10 supply module for power. Each PBUS strand can support up to 64 load units, and a separate transformer is needed for remote modules.
Mechanical Design: The module features a compact plastic housing, plug-in terminal blocks, LEDs for status indication, and a tool interface. It is designed for easy mounting on DIN rails.
Installation and Engineering: The module can be snapped onto DIN rails and connected to automation stations. Additional elements like the TXS1.12F10 supply module are necessary for migration from older systems like UNIGYR/VISONIK. The existing P-bus cabling must be extended for proper integration.
Technical Data: The module operates on a DC 24 V power supply, with a polling cycle of 0.3 seconds and a transmission rate of 62.5 kBaud. It supports a maximum line length of 200 meters per P-bus terminal block.
Standards and Compliance: The PXX-PBUS complies with various standards, including EN 60730-1 for automatic electrical controls and FCC regulations. It is also environmentally compliant with RoHS and other directives.
Disposal: The module must be disposed of according to European Directive 2012/19/EU and local regulations, as it is considered an electronic device.

Extension module PXX-PBUS-1

Integration of existing PT-I/O modules in Desigo Used with PXC50...D, PXC100...D or PXC200...D The PXX-PBUS extension module allows for integrating existing PT-I/O modules in Desigo. The PXX-PBUS extension module, when combined with a PXC50...D / PXC100...D / PXC200...D automation station and TXS1.12F10 supply module, replaces the UNIGYR and VISONIK process units as well as the PXC64-U, PXC128-U automation stations. • PT-I/O modules can continue to be used. • Existing periphery can be assumed without a change. • Control panel wiring can be assumed and need only be supplemented by new supply modules. See installation manual PT modules, M8102. Type summary Building Technologies

Extension module PXX-PBUS-2

Function Existing module carriers with PT-I/O modules can be connected to the PXX-PBUS extension module. All PT-I/O-Module are supported: PTM1... , PTM6.1PSI20-M, PTK1.23V02, PTK1.30V01, PTM50... , PTM52... , PTE-ASED.20, PTE-SED2 (see also PX Hardware overview N9202). The device serves as P-bus interface for modular automation stations PXC50...D, PXC100...D or PXC200...D in Desigo. The PT-I/O modules must now be supplied via the TXS1.12F10 supply module. In current installations, module supply was integrated in the UNIGYR/VISONIK process units or the PXC64-U / PXC128-U automation stations. One...
