1. Product Description
The O2I-Flex interface board provides the necessary power to the electronic components, and the control SST dynamic oxygen sensor can be set by the user to 0-25% and 0-100%. The entire measurement range is linear. The factory default is 0-25%. When configured with 0-100% span, customers can customize the analog output range to match the actual application. Outputs can be configured as: 4-20mA and 0-10VDC or RS232 interface

3. product characteristics
1） Provide necessary power circuits to power and control the SST dynamic oxygen sensor

2) High precision, linear output

3) Range optional: 0-25% and 0-100% O2 or in 0-100% mode via RS232 adjustable arbitrary range.

4) Multiple output modes: 4-20mA, 0-10VDC and RS232 communication interface

5) External trigger automatic or manual calibration; it can also be initialized by buttons on the board.

6) Can be in air (20.7%O2) or any other gas with known oxygen concentration.

7) The periodic 3.3VDC logic output can be diagnosed by directly monitoring the pump cycle.
