Key Points
- Adjustable for ranges of 2000, 5000, or 10,000 ppm CO2
- Field replaceable NDIR element
- Dual 3-wire 4-20mA and 0-5/0-10V (selectable)
Applications
- Controlling ventilation in response to occupancy
- Facilitates compliance with ASHRAE 62.1 standard for air quality
- Offices, conference rooms, and public assembly areas
Featuring a gold plated self-calibrating NDIR sensor for high accuracy. A built-in LCD display makes set up a snap, and a standard solid-state setpoint relay makes demand ventilation simple. Dual 4-20mA and 0-10/5 vdc outputs.
Easy to install and maintain
- Integrated display and push-button menus for field selectable scale, calibration, and operational modes
- Dual 4-20mA and 0-5V/0-10V output (jumper selectable)
- Integrated high-reliability solid-state set-point relay is ideal for direct control applications; easy to set up thanks to LCD
