    Description

    OEM-3, Ozone Detection and Control Board for OEMs

    Please ask for a quotation for your OEM quantities!

    This is a printed circuit board without housing and without power supply to be embedded into OEM customer's applications.
    The model OEM-3 is designed to control ozone generators and alarms based on an adjustable ozone concentration set point.
    It uses plug-in electrochemical sensor modules for 0- 0.1ppm, 0-1ppm, and 0-10ppm with other set points available as custom configurations.

    The sensors modules can also be located at a distance from the OEM-3 boards by optional 2m or 8m (6ft or 25ft) cables. These are readily available wire extension cables.
    The controller design incorporates hysteresis and a time delay (set at 8 seconds) to eliminate chatter and other excessive interactions between the sensor and generator.
    The OEM-3 should not be used outdoors or in the presence of NOx, nitric acid, acid gases, or halogen compound fumes.

    Features:

    • Choice of detection ranges @ 0.1, 1.0, or 10.0ppm (selection when ordering)
    • Power requirement: 12-24VDC/AC
    • Set point relay: 5A,  NC and NO
    • System connections: Terminal block
    • Signal outputs: 0-2VDC and 4-20mA

    Specifications:
    Sensor: Electrochemical SPEC Sensor
    Range: 0-0.1ppm, 0-1.0ppm, or 0-10.0ppm (please select when ordering!)
    Accuracy: Measuring range 0-0.1ppm: ±20% of the reading or ±0.03ppm
                         Measuring range 0-1ppm: ±10% of the reading or ±0.05ppm
                         Measuring range 0-10ppm: ±10% of the reading or ±0.2ppm
    Sensitivity: As low as 0.03ppm for the 0.1ppm module, these sensitivities will decrease if sensor module extension cables are used.
    Response time: < 60s to 90% full scale, immediate response time <5s.
    Turn-on, turn-off time delay: 8s standard
    Recommended temperature and humidity range: 50F-86F (+10°C to +30°C), 25%-75% RH. The circuit does include temperature compensation.
    Supply voltage required: 12-24VDC/AC, 250mA
    Relay ratings: SPDT non-latching. Contacts: 5A at 250VAC
    Size of main board: 83mm x 83mm (3.25" x 3.25"). Requires 28mm (1.125") clearance from top surface of board and 6mm (.250") clearance from bottom surface of the board.
    Warm-up time: Min. 1 hour before testing, for best results allow 12 hours before continued use.
    Zero adjustment: Re-zero function included standard
    Compatibility to OEM-2: The gas exposure inlet of the OEM-3 is located the same distance off the board as the tip of the SM-5 sensor on OEM-2 and the relay activation time is the same as in the OEM-2 product family
