Description

SIEMENS PXC36.D Building Automation Controller

Product Dimensions：

the SIEMENS PXC36.D is a high-performance modular automation station within the Desigo™ building automation system. It is designed for the comprehensive control of heating, ventilation, and air conditioning (HVAC) systems and other building utilities.

Product Detailed Description

The PXC36.D is a versatile, programmable controller used to manage primary building plants. It features a fixed number of onboard inputs/outputs (I/O) but is characterized by its “D” designation, which indicates it includes a built-in local display and keypad. This allows facility managers to monitor values, change setpoints, and acknowledge alarms directly at the controller without needing a separate laptop or HMI.

Technical Parameters

Product Advantages

• User-Friendly Interface: The onboard display provides immediate transparency into the system’s status, making it ideal for localized troubleshooting and quick adjustments.
• BACnet Compatibility: Fully supports BACnet communication protocols, ensuring seamless integration into multi-vendor Building Management Systems (BMS).
• Flexibility: Universal inputs can be configured via software for various types of sensors (passive LG-Ni1000, active 0…10V, or digital contacts), reducing the need for multiple module types.
• Longevity: Designed for industrial-grade durability with high resistance to electrical interference and environmental stress common in mechanical rooms.
• Scalability: It can operate as a standalone controller or as part of a large, networked system controlling an entire campus.

Important Considerations & Precautions

• Power Supply: Ensure the 24V AC transformer is appropriately sized. Connecting too many field devices to the controller’s internal power supply may lead to voltage drops or thermal shutdowns.
• Firmware Matching: When replacing an older PXC36 unit, ensure the firmware version is compatible with your existing Desigo CC or Insight workstation software.
• Polarity: Pay strict attention to the polarity of the BACnet MS/TP wiring (if used) to avoid communication collisions or data loss.
• Battery Maintenance: The controller uses a battery for the real-time clock and data retention during power outages. Check the battery status periodically to prevent data loss after a long shutdown.

Product Applications

The PXC36.D is primarily utilized in large-scale HVAC and building control:

• Air Handling Units (AHUs): Managing complex sequences for temperature, humidity, and CO2 control.
• Chiller/Boiler Plants: Coordinating the sequencing and optimization of multiple primary energy sources.
• District Heating: Controlling heat exchange stations and distribution pumps.
• Integrated Building Control: Monitoring and controlling lighting, power meters, and third-party systems via BACnet integration.
