2. Semiconductor sensor with 5 years long lifetime

3. LCD can display CO, temperature and humidity,

. It 4. Provide up to 010V analog output and 2 relay dry contact outputs

5. Two alternatives for the analog output: linearized over full range output or PID control output

6. Preset the first and the second alarm levels for measured carbon monoxide with a buzzer alarm

7. RS–485 communication interface, 15 KV antistatic protection, independent address setup

Application

Carbon monoxide is a deleterious gas with colorless and odorless character , which could be absorbed by lung quickly, the speed rate of combination of CO and hemoglobin more than 250 times with oxygen, then stops oxygen circulation around the body; which have big character of heavy toxicity, so CO poisoning have became a big problem around the world.
F2000IAQ-CO is used to monitor room CO level and temperature as well as relative humidity. With one 0~10VDC analog output and two dry-contact of relay outputs, F2000IAQ-CO can be as a programmable logical controller to direct control a ventilation system, and also as a transmitter of CO level to connect with a DDC/PLC.
F2000IAQ-CO can provide RS-485 communication interface to connect it with a PC or another control system, so make each room ventilation system be managed and controlled intelligently. It’s as a prevent monitor of CO potential leak and a controller of ventilation system in bellows application.
