RS-232 (optional) output. The same digital information is also sent to a 8-bit digital to analog converter (DAC) that produces the 0-10 VDC analog concentration signal and the 0-10 VDC analog range ID output. A current to voltage converter (E–I CONV) produces the 4-20 mADC analog concentration signal.
