Figure 3-2 Rear Panel Electrical Connectors for AC and DC Units

Analog Outputs: There are three DC output signal connectors with screw terminals on the panel. There are two wires per output with the polarity noted. See Figure 3-3. The outputs are:

0–10 V Concentration: Voltage is proportional to oxygen reading, from 0 V at 0 ppm oxygen to 10 V at full scale ppm oxygen. (Full scale = 100% of programmed range).

0–10 V Range ID:

3.33 V = Low Range, 6.66 V = High Range

4–20 mA % Range:

Current is proportional to oxygen reading, from 4

 

mA at 0 ppm oxygen to 20 mA at full scale ppm

 

oxygen. (Full scale = 100% of programmed

 

range).
