Senva TGD-ACN-A : Duct Mount Dual Toxic Gas CO/NO2 Sensor/Controller, 0-10V, 0-5V, 1-5V and 4-20mA Selectable Output, LCD Display, Clear/Tinted Enclosure, 7-Year Warranty

The Senva TGD-ACN-A is a duct mount dual toxic gas CO/NO2 sensor/controller designed for precise monitoring and control. with selectable outputs including 0-10V, 0-5V, 1-5V, and 4-20mA. TGD-ACN-A includes an LCD display that provides clear visibility of readings. Operating on a power supply of 15-30VDC/24VAC, the sensor/controller features programmable analog outputs and adjustable scaling for CO and NO2 outputs. It includes a fan relay with customizable setpoints and an alarm relay for enhanced safety. The 3-1/2 digit LCD displays CO and NO2 levels, while LEDs indicate normal, warning/fan relay, and alarm/alarm relay statuses. Equipped with a reliable electrochemical CO sensor and an electrochemical NO2 sensor, both with a lifespan exceeding 7 years, this device ensures accurate monitoring. The enclosure, made of ABS/Polycarbonate, is suitable for wall and duct installations, conforming to UL61010-1, UL, cUL, and CE compliance standards. With a coverage area of 5000-7500 square feet, this sensor/controller guarantees efficient and long-lasting toxic gas monitoring within proximity to a Senva TG sensor.

Applications

  • Ensure adequate air flow in occupied spaces
  • Ideal fo parking lot garages 
  • Monitor multiple toxic gases with one mounted unit
  • Alert occupants of elevated gas levels
  • Directly control exhaust fans
