Product Description

The Siemens PXC22.1-E.D is a compact, freely programmable automation station from the Desigo PX building automation series. It is designed for efficient, reliable control of HVAC and building services equipment.

• Model: PXC22.1-E.D (Desigo PX Compact Series)
• Communication: BACnet over IP (Ethernet)
• Function: Freely programmable controller for system-specific or application-specific HVAC tasks.
• Capacity: 22 physical data points (fixed mix, extendable).

Product Parameters

• Physical I/O: 22 total points (16 Universal Inputs/Outputs [UIO], 6 Digital Outputs [DO]).
• Extendability: Can be expanded using TX-I/O and/or TX Open modules.
• Operating Voltage: AC 24 V (19.2…28.8 V), 50/60 Hz.
• Power Consumption: 26 VA.
• Degree of Protection: IP20.
• Dimensions: 293 x 176 x 77 mm.
• Room Unit Support: PPS2 bus connection for QAX series room units.

Product Advantages

• Native BACnet: Full compatibility with BACnet standards (B-BC profile), allowing seamless integration into building management systems (BMS).
• Freely Programmable: Offers high flexibility for complex control strategies using the Desigo Xworks Plus engineering tool.
• Integrated Management: Includes advanced built-in functions such as alarm management (routing), time scheduling, trend logging, and remote management.
• Robustness: Features internal power supply with brownout protection and power recovery circuitry to ensure equipment stability during voltage fluctuations.
• Scalability: While it provides a fixed data point mix, its ability to expand via TX-I/O makes it adaptable to larger plant requirements.

Product Applications

• HVAC Control: Air handling units (AHUs), heating/cooling plants, and zone control.
• Building Services: Monitoring and control of lighting, shading, and general facility automation.
• Standalone or Networked: Suitable for isolated, smaller plant rooms or as part of a large-scale enterprise building automation network.

Precautions

• Qualified Personnel: Installation, programming, and commissioning must be performed by trained building automation professionals.
• Environment: The device is rated IP20; it should be installed in a clean, dry, and protected environment (e.g., control cabinet).
• Battery Maintenance: The device uses internal batteries for real-time clock and data backup (CR2032/AA Lithium). Ensure they are replaced according to the maintenance schedule to prevent data loss.
• Cybersecurity: As an IP-enabled device, it should be protected by appropriate network security measures (e.g., firewall, VLANs) to prevent unauthorized access.
• Firmware/Updates: Always check for the latest firmware or security patches from Siemens to ensure compliance with current safety standards.
