    Theory Of Operation The 20 mA current loop format transfers information using changes in current flow rather than voltage levels to indicate logic states. Logic levels are represented by current flow, and absence of current flow. A loop circuit is formed between each pair of SO-20 modules. Three loop circuits are shown in the figure below, loops A/B, B/C and C/A.
