It uses an electrochemical sensing element to detect CO concentrations across field-selectable ranges of 0 to 100, 0 to 200, 0 to 300, and 0 to 500 ppm. Accuracy is rated at plus or minus 3% for readings below 200 ppm and plus or minus 5% for readings from 201 to 500 ppm. Output options include 4 to 20 mA, 0 or 1 to 5 VDC, and 0 or 2 to 10 VDC, with dual SPDT relay contacts and an onboard LCD display for local readings.\u003c\/p\u003e\u003cp\u003eThis sensor is suited for parking garages, mechanical rooms, loading docks, and other locations where CO monitoring is required by code or facility safety protocol. The IP66-rated enclosure makes it appropriate for areas exposed to dust, moisture, or washdown conditions. HVAC controls technicians and building automation specialists typically integrate this sensor into BAS or ventilation control systems where analog or relay outputs are needed to trigger fan operation or alarms based on CO thresholds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eElectrochemical CO sensing with field-selectable ranges: 0-100, 0-200, 0-300, and 0-500 ppm\u003c\/li\u003e\n\u003cli\u003ePlus or minus 3% accuracy below 200 ppm; plus or minus 5% accuracy from 201 to 500 ppm\u003c\/li\u003e\n\u003cli\u003eDual analog outputs: 4 to 20 mA and 0(1) to 5 VDC or 0(2) to 10 VDC\u003c\/li\u003e\n\u003cli\u003eTwo SPDT relay outputs for direct load switching or alarm integration\u003c\/li\u003e\n\u003cli\u003eLCD display for local CO level readout without additional test equipment\u003c\/li\u003e\n\u003cli\u003eIP66-rated enclosure rated for rough service and wet or dusty locations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for integration with building automation systems and ventilation controllers that accept standard 4 to 20 mA or 0 to 10 VDC analog inputs, as well as SPDT dry-contact relay inputs, in commercial and industrial CO monitoring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed controls technicians or building automation specialists. Power down the control panel or disconnect the low-voltage circuit before wiring. The sensor accepts 18 to 28 VAC or 18 to 40 VDC supply voltage — confirm the supply matches the unit label before energizing. Follow local codes and the manufacturer wiring diagram for relay and analog output terminations; do not exceed the relay contact ratings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensing Technology\u003c\/strong\u003e: Electrochemical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Ranges (Field Selectable)\u003c\/strong\u003e: 0-100 ppm, 0-200 ppm, 0-300 ppm, 0-500 ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: Plus or minus 3% (0-200 ppm), plus or minus 5% (201-500 ppm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Voltage\u003c\/strong\u003e: 18 to 28 VAC or 18 to 40 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnalog Output\u003c\/strong\u003e: 4-20 mA, 0(1) to 5 VDC, 0(2) to 10 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Output\u003c\/strong\u003e: 2 x SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: IP66\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Wall Mount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BAPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BA\/D-CO-NO2-V-BB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BAPI","offers":[{"title":"Default Title","offer_id":51620672504114,"sku":"BA\/D-CO-NO2-V-BB","price":449.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4840e1307df9d16aac0cd8a97fb3e2e.png?v=1787345149","url":"https:\/\/voomisupply.com\/products\/bapi-ba-d-co-no2-v-bb-co-sensor-0-500-ppm-wall-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
