Supported Applications
The ACI CO Room Series is designed for the continuous monitoring of carbon monoxide (CO) levels, specifically targeting vehicle exhaust in non-hazardous areas. The series utilizes a wide spectrum electrochemical sensor to measure environmental CO concentrations.
- Detection and monitoring of Carbon Monoxide (CO)
Operating Conditions & Performance
The transmitter operates within an ambient temperature range of -4°F to 104°F (-20°C to 40°C) and a humidity rating of 15 to 90% RH continuous, non-condensing; or 0 to 99% RH intermittent, non-condensing. The device is rated for atmospheric pressure +/- 10%. Performance specifications include an accuracy of +/- 2.5% of Reading and repeatability of +/- 1% of Reading.
- Measurement Range: Factory set at 0 – 125 ppm; field adjustable to 0 – 250 ppm
- Response Time: Less than 60 Seconds for 90% of step change
- Sensor Life: ~ 5 years under Normal Conditions
- Coverage Area: 7500 sq. ft; 49' Radius
Configuration Options
The series is offered in a standard NEMA 1 rated enclosure constructed from Polycarbonate/ABS Blend, UL94V-0. The unit features fixed terminal blocks for power wiring using 16 to 26 AWG (0.2 to 1.00 mm²) Shielded Twisted Pair cables.
Outputs and Indicators
- Analog Outputs: 4-20 mA or 2-10V Jumper Selectable
- Indicators (Optional): Alphanumeric, 2 line X 8 digit LCD; (2) Red LED's for Relay Status
Relay and Alarm Options
An optional configuration includes two SPDT Form C dry contact relays and a buzzer. The relay rating is 1A @ 30 VDC/0.5A @ 125 VAC (Resistive Load) with a life expectancy of 200,000 cycles minimum at 1A @ 30 VDC. Time delays for actuation and de-actuation are configurable from 0 to 60 Minutes in 5 minute Increments.
Power Supply
- Voltage: 24 VAC +/- 10% Floating; 24 VAC +/- 10%, One side Grounded; or 24 VDC
- Current Draw: 100 mA nominal | 250 mA maximum
Accessories and Maintenance
The series supports a Calibration Adapter, Replacement CO Sensing Element, and Gas Cal Kit. Sensors should be tested for accuracy every 6 months; recalibration or sensor replacement is required if necessary. When installed above 3000' above sea level, the transmitters must be verified for accuracy and re-calibrated after installation.
Key Product Differences
- CO-R (Item #102151): CO Room Mount with Standard Room Enclosure.
- CO-R-RB-D (Item #107556): CO Room Mount including Display, Relay, and Buzzer in a Standard Enclosure.
The series is not compatible with the Q4C II, M-Controller2, or Q-Controller. Modbus RTU communication is not supported by this product line.
