Troubleshooting a 4-20mA Current loop
The basic layout of every 4-20mA loop consists of a power supply, a transmitter, and passive loop devices. The supply produces the energy to run the loop. The transmitter controls

Why 4-20mA Standard is so popular ?
4-20mA Standard 4-20mA has an inherent ‘live zero’. Zero engineering units is 4.0mA, not 0.0mA. 0.0mA indicates an open circuit, a failure or a fault mode like cut wires or
Basics of 4 to 20 mA analog Signals
The most popular form of signal transmission used in modern industrial instrumentation systems is the 4 to 20 milliamp DC standard. This is an analog signal standard, meaning that the
