A major application of current loops is the industry de facto standard 4–20 mA current loop for process control applications, where they are extensively used to carry signals from process instrumentation to proportional–integral–derivative (PID) controllers, supervisory control and data acquisition (SCADA) systems, and programmable logic ...
More than two teleprinters could be connected on a single circuit allowing a simple form of networking. [1] Older teleprinters used a 60 mA current loop. Later machines, such as the Teletype Model 33 , operated on a lower 20 mA current level and most early minicomputers featured a 20 mA current loop interface, with an RS-232 port generally ...
