Current Loop Wiring Diagram. A 4 20ma current loop circuit is shown in figure 1. Control function currents come from the remote control console at the dispatch office end of a circuit.
The tab connecting the hot terminals on the receptacle is removed and the source hot is connected to the bottom half. What is speaker impedance. Loop in as per diagram above.
Also the same wiring circuit diagram can be used for 2 way lighting or controlling electrical appliances from two different places by using two way switches.
What is speaker impedance. Speaker basics and speaker wiring explained 1. So a single pole double throw has a mutual point and two other points. A 4 20ma current loop circuit is shown in figure 1.
