Description

SIEMENS PXC200.D Building Automation Controller

Product Dimensions：

The Siemens PXC200.D is a high-performance, modular automation station belonging to the Desigo CC / Desigo PX building automation and control system (BACS) family. It is engineered to control, monitor, and optimize large-scale HVAC systems and complex building automation processes.

Product Detailed Description

The PXC200.D acts as a central control unit in building management networks. It processes incoming signals from sensors, executes programmed control logic (using Siemens DXR/PXC block programming), and outputs commands to field actuators.

The “.D” designation indicates that it includes a built-in local user interface (LUI) with an LCD display and keypad, allowing operators to inspect values, override points, and acknowledge alarms directly at the control panel without requiring a PC.

Technical Parameters

Product Advantages

• Built-in Local User Interface (LUI): Allows engineers and facility managers to view system status, edit setpoints, and reset alarms directly from the front panel.
• Seamless BACnet Integration: Fully certified BACnet Building Controller (B-BC profile), ensuring open interoperability with third-party building control equipment.
• Modular TX-I/O Expansion: Highly flexible system architecture—you can stack compact TX-I/O modules directly onto the station to customize the exact mix of digital and analog inputs/outputs needed.
• Standalone Intelligence: Operates fully autonomously with its internal clock and stored programs; even if network communication fails, local plant control remains uninterrupted.
• Energy-Efficiency Algorithms: Native support for advanced energy-saving strategies (e.g., night setback, demand-controlled ventilation, dynamic setpoint reset).

Important Considerations & Precautions

• Power Supply Quality: Always use a dedicated 24 V AC safety extra-low voltage (SELV) or protective extra-low voltage (PELV) transformer. Do not share power with high-noise inductive loads.
• TX-I/O Bus Length & Power: When connecting multiple TX-I/O modules, observe the maximum bus length and current consumption. Adding a bus power supply module (TXS1.12F10) may be required for larger I/O configurations.
• Battery Replacement: The internal battery powers the Real-Time Clock during power outages. Check battery status during routine maintenance to prevent date/time loss on power cycles.
• ESD & Panel Environment: Mount inside a clean, dry IP54-rated control cabinet to prevent dust or moisture buildup on open terminal connections.

Product Applications

The PXC200.D is designed for medium to large-scale facility management tasks:

• Central HVAC Control: Managing large Air Handling Units (AHUs), central chiller plants, and boiler heating circuits.
• Commercial Buildings & Hospitals: Regulating environmental parameters (temperature, humidity, pressure differentials) in critical zones.
• Data Centers: Precision cooling control and environmental monitoring.
• District Heating & Cooling: Managing heat exchangers and distribution pump stations.
