OEM-2 Ozone Controller

OEM-2 Ozone Controller is great for integrated solutions or use within your ozone generator. A simple and effective method to control ozone levels, or shut down equipment in the event of an ozone leak.  Available range of 0-0.1ppm.

The OEM-2 is a 12/24 VDC powered board that offers a 4-20 mA output. 

For reference, the OEM-1 is a 120 VAC powered device that offers a 0-1 VDC output.

The model OEM-2 is a system to control ozone generators and alarms based on an adjustable ozone concentration set point. It is designed to work with plug-in sensor modules for 0-0.1 ppm. These are specified when ordering by putting the ppm range after the model number. For example, a 0.1 ppm OEM-2 board system would be OEM-2-.1 and the replacement sensor module for it would be SM-1-.1. These same sensor modules also work in our OEM-1 boards, which have features such as being powered by 110/220 VAC. The sensors modules can also be located at a distance from the OEM-2 boards by 2 or 8 meter cables. These are readily available DIN M/F 5 pin extension cables.

One component of the OEM-2 system is the base board which incorporates the power supply, final signal processing, set-point controls, and the output relay. The other component is the sensor mounted with its associated electronics in a cylindrical DIN plug. This is pre-calibrated in our lab so that the sensor module and main board module together work as a calibrated system. If the sensor module is damaged, it is simply replaced by another precalibrated module.

When it comes to calibrating your OEM-2 Ozone Controller, you should replace your sensor annually.


OEM-2 Ozone Sensor Replacement:

Sensor replacement on OEM-2 is simply plug-n-play.  Remove the old SM-1 and replace with new.
