MODBUS-Analog NDIR dualbeam CO2 sensor Description This sensor gives information concerning carbon dioxide (CO2) concentration levels, the essential element in air quality monitoring and control in occupied buildings. This device has new sophisticated features as Scaling Control function where the user can scale the analogue output as trigger concentrations to connect and control ventilators, motorized grilles, air dampers…and different actuators devices where this proportional analogue output is accepted. The device analog and digital outputs are isolated from the main power supply Current and incoming legislation requires CO2 gas monitoring within building environments for optimal control of air quality. Moreover, such CO2 gas monitoring is employed within demand control ventilation systems used for building heating ventilation and air conditioning. Features  NDIR Dual, long life, reliability. No calibration required  400-4000 ppm CO2 measurement sensor range  16 bits MODBUS RTU word – MODBUS parameters remotely can be changed Working Modesfrom the main power supply  Isolated outputs  Unique MAC Address identifier for remote control and web applications  Configurable baudrate by console, 9600 bps by default  Configurable physical MODBUS Address by console (default 16)  Configurable Settings: Thresholds, PPM levels and intensity LED lights  Scaling Function‐ Configurable Analogue Output Range  Configurable Digital Output (max. load 150 mA) locally Trigger – 800 ppm by default  PID Controller Working Mode – Setpoint also configurable by BMS Indoor Air Quality Measurement in Offices, Schools, nurseries, kindergartens, Cinemas, Conference rooms, hotels and residential areas DCV- Demand Controlled Ventilation for energy savings HVAC applications for building management Home air quality control Range ppm definition Options (1.2) Range 2 (1.3) Manual. Scaling Function 0 … 2500 ppm [x1,x2]=[0, 4000] Analogue Output Configuration TRIGGER Digital Output [y1,y2]=[0,10v] in voltage [y1,y2]=[0,20mA] in current example: Output [V] y1=0, y2=5 v, x1=400, x2=1200 0 v is 400 ppm 5 v is 1200 ppm 2. PID Controller MODE Definition parameters Kp, Ki, Kd if Kd=0 ‐> PI controller if Ki=0, Kd=0 ‐> P controller Set point 600, 900, 1200 ppm Configurable also manually by jumpers Output Analogue Output Digital Output Default Setting configurations
