Automation Components Inc (ACI) CO-R-RB-D Transmitter

The ACI CO-R-RB-D Transmitter is a high-precision carbon monoxide sensor engineered for continuous atmospheric monitoring in non-hazardous environments. Utilizing a long-life electrochemical sensor, this unit effectively detects toxic vehicle exhaust levels, making it an essential component for parking garage gas detection, warehouses, and loading docks. This specific model features an integrated LCD display for real-time visual feedback, alongside a local audible buzzer and (2) SPDT Form 1C relays for direct control of ventilation fans or alarm systems. Designed to meet OSHA standards and integrate seamlessly into an HVAC Building Automation System, the transmitter offers a factory-set range of 0 to 125 ppm, which is field-adjustable up to 250 ppm. Housed in a durable NEMA 1 rated ABS polycarbonate enclosure, the CO-R-RB-D ensures reliable indoor air quality monitoring and safety compliance across diverse commercial and industrial applications.

Key Benefits

• Enhanced Safety: Integrated 85 dB buzzer and dual relays provide immediate local alerts and automated ventilation control.
• Visual Monitoring: Built-in LCD display allows for easy onsite calibration and real-time PPM concentration tracking.
• Long-Term Reliability: Features a high-quality electrochemical sensor with an expected lifespan of approximately 5 years under normal conditions.
• Flexible Integration: Jumper-selectable 4-20 mA or 2-10 VDC analog outputs ensure compatibility with most controllers.
• Wide Coverage: A single unit provides effective monitoring for areas up to 7,500 square feet.

Common Questions

Where should the CO-R-RB-D be installed for maximum effectiveness?
For optimal carbon monoxide detection, sensors should be mounted in the "breathing zone," typically 4 to 6 feet above the finished floor, as CO has a similar density to air.

How often does this transmitter require calibration?
To maintain peak accuracy (± 2.5% of reading), it is recommended to perform a bump test or calibration annually, or as required by local building codes and OSHA regulations.

Can this unit be used in outdoor or wash-down environments?
The CO-R-RB-D comes in a NEMA 1 enclosure intended for indoor use. For applications requiring water or dust protection, a NEMA 4X version should be specified.
