Product Specification

OEM-2 OEM OZONE CONTROLLER GENERAL:

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, 0-1 ppm, and 0-10 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 precalibrated 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.

The design incorporates hysteresis and time delay (set at 8 seconds except for special orders) to eliminate chatter and other excessive interactions between the sensor and generator. The SPDT relay contacts will handle up to 5 amps at 250 volts. The OEM-2 should not be used outdoors or in the presence of NOx, nitric acid, acid gases, or halogen compound fumes.

Allow warm-up according to the table below. At least 24 hours is recommended if the system hasn't been used for a week or so. This is because the sensor can absorb VOCs when it is not in use.
