Are you asking about a laboratory or an online process sulfur oxide analyzer manufacturer? It is difficult to estimate the outputs without knowing some details. The online analyzers normally include a 4-20 mAdc output; and likely an EIA/TIA-485 or Ethernet output. Lab analyzer options may be fewer.
Is this related to heater stack measurement?
Some analyzers may split the multiple sulfur oxide compound separation. Some not.
Two 4-20 mAdc signals are likely for the DCS input regardless of the separation. One output is powered by 24 Vdc from the DCS; another output is powered by the analyzer and requires a DCS input that does not provide the 24 Vdc.
Perhaps you already know the manufacturer and model details; or perhaps this the beginning of your analyzer quest. Consider explaining more background details.
