System Power Requirements:

The Model OT-2 System requires a 12 VDC (nominal), reverse polarity protected power source.

Observe good wiring practices. For hazardous area applications, the Model OT-2 System must be pow- ered by a source that is consistent with intrinsically safe operation.

Analog Outputs:

1-5 VDC: Voltage increases linearly with increasing oxygen, from 1 VDC at 0 ppm to 5 VDC at full scale ppm.
