Description

Siemens PXC36.1.D Building Automation Station

Product Dimensions：

The Siemens PXC36.1.D is a high-performance, compact automation station from the Desigo PX range. It is designed to control HVAC and building services systems, offering a fixed yet versatile mix of physical data points and seamless integration into larger building management systems.

Product Detailed Description

The PXC36.1.D is a freely programmable controller that supports native BACnet on LonTalk communication. Unlike standard modular controllers, the “compact” series provides a fixed number of inputs and outputs (I/O) directly on the unit, though the “.1” version specifically allows for further expansion via the Island Bus, making it highly scalable for larger plant rooms.

Technical Parameters

Product Advantages

• Highly Scalable: While it has 36 on-board points, the Island Bus allows you to add TX-I/O modules for additional points or TX Open modules to integrate third-party protocols (like Modbus or M-Bus).
• Native BACnet: Fully BTL-tested BACnet communication ensures seamless interoperability with other BACnet devices and management stations (like Desigo CC).
• Flexible Programming: Programmed using the D-MAP language (graphical function blocks), allowing for complex control logic tailored to specific mechanical systems.
• VisiSafe & Diagnostics: Includes clear LED indicators for device status, system faults, and relay positions, simplifying on-site troubleshooting.
• Reliability: Features “Brownout Protection” and start-up management to protect connected field devices during power fluctuations.

Important Considerations (Precautions)

• Network Limits: Being a LonTalk device, ensure you adhere to LonWorks topology rules (terminators, cable lengths) to avoid communication lag.
• Polarity: When wiring the 24V AC power, maintain consistent polarity across all controllers in the network to prevent ground loops.
• Static Protection: The unit contains sensitive electronics; always use an ESD wrist strap when handling the internal battery or service pins.
• Programming Software: Requires Desigo Xworks Plus for engineering and commissioning. Ensure your software version supports V6.x firmware or higher for full feature set compatibility.

Product Applications

The PXC36.1.D is ideally suited for managing medium-to-large mechanical plants:

• Air Handling Units (AHU): Managing multi-stage heating/cooling, humidity, and variable speed fans.
• Boiler & Chiller Plants: Sequencing multiple units for energy efficiency and lead-lag rotation.
• District Heating: Primary and secondary loop control with heat meter integration via expansion modules.
• Complex Zone Control: Managing large open-plan office spaces requiring multiple room unit inputs and VAV (Variable Air Volume) control.
