PXC001-E.D SIEMENS

PXC001-E.D SIEMENS Basis unit

Product  Description：

The PXC001-E.D acts as the central intelligence of a building's HVAC and facility management system. It is a programmable controller that uses the BACnet communication protocol over Ethernet (BACnet/IP). Its main function is to provide a platform for system-wide functions such as global scheduling, alarming, and trend logging. Unlike smaller room controllers, the PXC001-E.D is often used to integrate third-party devices via open protocols and to bridge data between different network segments. It features a modular construction and is designed for mounting on standard DIN rails.

Product Parameters

• Operating Voltage: $24 \text{ VAC}$ (plus or minus $20\%$) at $50/60 \text{ Hz}$.

• Power Consumption: Maximum $24 \text{ VA}$.

• Communication Interface: $10/100$ Base-T Ethernet port (RJ45) for BACnet/IP communication.

• Expansion Ports: Includes an LonWorks (Island bus) or PPS2 interface depending on the specific module configuration used for peripheral communication.

• Processor: High-speed 32-bit processor designed for deterministic real-time control.

• Memory: Sufficient Flash and RAM to store large user programs, extensive trend data, and complex site graphics.

• Protection Rating: IP20 (intended for installation in a protective control panel).

• Operating Environment: $0\text{°C}$ to $50\text{°C}$ ambient temperature with $5\%$ to $95\%$ non-condensing relative humidity.

• Real-time Clock: Integrated battery-backed clock for maintaining schedules during power outages.

Product Advantages

A major advantage of the PXC001-E.D is its Open Integration Capability. By utilizing BACnet/IP, it ensures seamless interoperability with other manufacturers' equipment, preventing vendor lock-in. The High Scalability of the Desigo system means this controller can manage anything from a single large air handling unit to an entire floor's worth of diverse mechanical equipment.

The Sophisticated Diagnostic Tools built into the firmware allow technicians to troubleshoot network issues directly through the web interface or specialized Siemens software. Furthermore, the Energy Optimization Functions embedded in the Desigo library allow for advanced strategies like demand-based ventilation and weather-compensated heating, which significantly reduce a building's carbon footprint and operational costs.

Important Considerations and Precautions

When deploying the PXC001-E.D, it is essential to follow Strict Cybersecurity Protocols. Because the device resides on an Ethernet network, it should be placed behind a secure firewall and never exposed directly to the public internet. During installation, the $24 \text{ VAC}$ Power Grounding must be consistent throughout the panel to prevent ground loops that could disrupt sensitive communication signals.

It is also important to note that the PXC001-E.D does not have onboard physical I/O; it manages inputs and outputs through distributed TX-I/O modules or other field controllers. Therefore, the total data point count must be calculated during the design phase to ensure the processor does not exceed its recommended load. Lastly, always ensure the Internal Battery is checked during annual maintenance to guarantee that the database and clock are preserved during a power failure.

Product Applications

The PXC001-E.D is typically found in large-scale commercial and institutional buildings.

• Central Plant Control: Managing large boiler and chiller plants, including primary/secondary pump sequencing and cooling tower optimization.

• Campus Integration: Serving as a master gateway to aggregate data from multiple buildings into a single management station.

• Complex Air Handling: Controlling high-spec AHUs in hospitals or laboratories that require precise pressure, humidity, and temperature control.

• Third-Party Integration: Integrating Modbus or M-Bus meters and devices into the BACnet environment for centralized energy monitoring.

• Lighting and Shading Coordination: Acting as the high-level logic controller that links HVAC states with lighting and blind control systems to maximize energy savings.
