Product Specification

OEM-3 OZONE CONTROLLER GENERAL:

The OEM-3 is a system to control ozone generators and alarms based on an adjustable ozone concentration set point. It is designed to work with user-replaceable sensor modules that are preconfigured for ozone detection ranges of 0-0.1 ppm, 0-1 ppm, and 0-10 ppm. The desired set point is specified when ordering. For example: a 1 ppm OEM-3 would be OEM-3-1, and the replacement ozone sensor module would be OEM-O3-1. The Eco Sensors’ SM-100 may be used to operate the sensor modules remotely at cable lengths up to 8 m (25 ft).

The OEM-3 incorporates the power supply, final sensor signal processing, set-point controls, analog output signals, and the output relay. The user-replaceable sensor module includes the ozone sensor and its associated electronics in a square, flat board with an edge connector. The sensor module is pre-calibrated in our lab so that the sensor module and OEM-3 work together as a calibrated system. If the sensor module is damaged or loses accuracy, it is simply replaced by another pre-calibrated module.

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 SPDT relay contacts will handle up to 5 A at 250 VAC. The OEM-3 should not be used outdoors or in the presence of NOx, nitric acid, acid gases, or halogen compound fumes (see Precautions section).

OEM-3 OZONE CONTROLLER Features:

SPDT non-latching relay.NO & NC contacts are available. Relay commutates at set point. Contact rating: 5 A at 250 VAC
Zero Buttonallows re-zeroing of sensor output.
0-2 V analog voltage outputwhich is a buffered version of the sensor module signal. 1 V represents the calibration point of the sensor module.
4-20mAcurrent outputwhich is proportional to the sensor module’s output. 12 mA represents the calibration point of the sensor module.
Driver circuit for an audible alarm, including an acknowledge switch input to silence this alarm. The alarm will turn on again after the ozone level drops below the switch threshold and then rises again.
SM-100 extension cables up to 8 mare available for remote mounting of the sensor module
