It outputs a 4-20mA current signal and a 2-10VDC voltage signal simultaneously, giving building automation and control systems direct analog readings without additional signal conversion. The default measurement range is 0-125 PPM, with a maximum ceiling of 250 PPM, and the onboard LCD displays live CO concentration for field verification. An integrated relay and audible buzzer provide local alarm output when CO levels exceed set thresholds. Licensed HVAC technicians, building automation contractors, and industrial safety professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis sensor is suited for room-level CO detection across a wide range of applications including industrial facilities, oil and gas environments, laboratories, agricultural buildings, transportation hubs, and mining operations. The room-mount form factor positions the sensor at occupant-breathing height for accurate zone-level readings. The dual analog outputs make it compatible with most DDC controllers and building management systems that accept standard 4-20mA or 2-10VDC inputs, allowing integration into existing control sequences for ventilation response or alarm annunciation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDefault range of 0-125 PPM with a maximum measurable range up to 250 PPM for flexible threshold configuration\u003c\/li\u003e\n  \u003cli\u003eSimultaneous 4-20mA and 2-10VDC analog outputs for direct BAS or DDC controller integration\u003c\/li\u003e\n  \u003cli\u003eOnboard LCD displays real-time CO concentration for on-site verification without test equipment\u003c\/li\u003e\n  \u003cli\u003eIntegrated relay and audible buzzer enable local alarm response independent of the control system\u003c\/li\u003e\n  \u003cli\u003eRoom-mount enclosure designed for wall installation at occupant level\u003c\/li\u003e\n  \u003cli\u003eBroad application suitability covering industrial, agricultural, laboratory, and transportation environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with building automation systems and DDC controllers that accept standard 4-20mA current or 2-10VDC voltage analog inputs.

De-energize the control panel and verify zero voltage at the terminal block before wiring the sensor outputs. Follow the sensor mounting height recommendations for the target application to ensure accurate zone-level readings. Verify output signal type selection and scaling at the controller before commissioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDefault Measurement Range\u003c\/strong\u003e: 0-125 PPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 250 PPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Sensor Range\u003c\/strong\u003e: 0-2000 PPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Signal\u003c\/strong\u003e: 4-20mA and 2-10VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Type\u003c\/strong\u003e: Current and Voltage (simultaneous)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: LCD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocal Alarm\u003c\/strong\u003e: Relay and audible buzzer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Room mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Industrial, oil and gas, laboratories, agriculture, transportation, mining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CO-R-RB-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACI","offers":[{"title":"Default Title","offer_id":51283906887986,"sku":"CO-R-RB-D","price":824.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279067.jpg?v=1781062945","url":"https:\/\/voomisupply.com\/products\/aci-co-r-rb-d-carbon-monoxide-sensor-room-mount-4-20ma","provider":"Voomi Supply","version":"1.0","type":"link"}
