In electricalsignallingan analogcurrent loopis used where a device must be monitored or controlled remotely over a pair of conductors. Only one current level can be present at any time. A major application of current loops is the industry standard 4-20 mA current loop forprocess controlapplications, where they are extensively used to carry signals from processinstrumentationtoPID controllers,SCADAsystems, andProgrammable logic controllers. They are also used to transmit controller outputs to the modulating field devices such ascontrol valves. These loops have the advantages of simplicity and noise immunity, and have a large international user and equipment supplier base. Some 4-20 mA field devices can be powered by the current loop itself, removing the need for separate power supplies, and the "smart"HART Protocoluses the loop for communications between field devices and controllers. VariousAutomation Protocolsmay replace analog current loops, but 4-20 mA is still a principal industrial standard.+ Read More
