Siemens Building Technology QPA2062 Sensor

The Siemens Building Technology QPA2062 Sensor is a multi-parameter room air quality sensor engineered for high-demand HVAC and building automation systems. Built for professional-grade reliability, this unit integrates a Non-Dispersive Infrared (NDIR) CO2 gas sensor with active temperature and relative humidity monitoring to facilitate precision Demand Controlled Ventilation (DCV). The 0-2000 ppm CO2 measuring range provides a stable 0-10V or 4-20mA selectable linear output, ensuring seamless integration with Siemens Desigo or any third-party Direct Digital Control (DDC) building automation systems. With no manual recalibration required, this sensor maintains long-term accuracy by compensating for sensor drift through self-correcting CO2 sensing technology. The multi-output configuration allows for independent 0-10V signals for CO2, temperature, and 0-95% RH, making it an essential component for optimizing occupant comfort and operational efficiency in offices, administrative buildings, or schools using low-maintenance ductless and ducted AHU controls.

• Triple Sensing Capability: Simultaneously monitors CO2, temperature, and relative humidity, reducing the total amount of hardware required on the wall and simplifying terminal block wiring.
• Maintenance-Free Operation: Features an infrared absorption sensing element designed to last and resist drift without the need for periodic field calibration.
• Versatile Signaling: Field-selectable active output signals (0-10Vdc or 4-20mA) provide maximum flexibility for varied building controller requirements.
• Durable Enclosure: Low-profile IP30 design specifically tailored for standard wall-mount applications with quick-connect screw terminals for 8-22 AWG wiring.

Does the QPA2062 require a local display for field setup?
No, this specific model (QPA2062) is a "no display" variant, providing a clean, tamper-resistant aesthetic that is ideal for public spaces where visual ppm readings are not required by the end-user.

Can I use this sensor in life safety or safety-critical CO2 monitoring?
No, the Siemens QPA series is strictly intended for comfort and ventilation control; it is not suited for safety-related applications or refrigerant leak detection.

Is this sensor compatible with 24VAC or 24VDC power?
Yes, the QPA2062 is designed for universal power compatibility, operating reliably on AC 24 V (Class 2) or DC 15 to 35 V systems.
