Veris Industries GWNMXX Sensor

The Veris Industries GWNMXX is a versatile modular gas sensor platform designed for high-performance environmental monitoring in commercial and industrial facilities. This base unit operates on 24VAC/DC input power and provides a reliable 4-20mA analog output alongside an integrated SPDT relay for direct control of ventilation fans or alarm systems. Engineered for seamless integration into Building Automation Systems (BAS), the GWNMXX supports a variety of field-replaceable AG Series sensor modules (sold separately), allowing for the detection of Carbon Monoxide (CO), Nitrogen Dioxide (NO2), or refrigerants without the need to replace the entire housing. Its robust IP20-rated enclosure mounts directly to a standard single-gang electrical box, simplifying installation in parking garages, mechanical rooms, and vehicle maintenance bays. The microprocessor-controlled design eliminates the need for field calibration of the base, while the three-color onboard LED indicators provide immediate local status for power, low setpoint, and high setpoint conditions.

• Modular Flexibility: Swap AG Series gas modules in seconds to change gas types or replace depleted sensors without disturbing system wiring.
• Direct Fan Management: The built-in form C relay allows for multi-stage fan actuation or local alarm signaling based on gas concentration setpoints.
• Simplified Commissioning: Field-replaceable modules come pre-calibrated, and the platform features microprocessor stability for long-term operational accuracy.
• Visual Diagnostics: High-visibility LED status indicators (Green, Yellow, Red) allow technicians to verify system operation and alarm status at a glance.
• Universal Compatibility: Standard 4-20mA output ensures the device communicates effectively with any controller supporting industrial analog signals.

Does the GWNMXX include the gas sensing element?
No, the GWNMXX is the modular platform base and electronics. A separate AG Series sensor module, such as the AG01 for Carbon Monoxide or AG02 for Nitrogen Dioxide, must be installed for gas detection.

Can I use this for both hazardous and non-hazardous locations?
The GWNMXX is IP20 rated and designed for indoor commercial/industrial use in non-classified areas like parking decks and mechanical rooms. It is not rated for explosion-proof environments.

What power source is required for the GWNMXX?
This sensor platform is a Class 2 device that accepts 24 VAC/DC nominal input, making it compatible with standard HVAC and building automation power supplies.
