Shema Tokovaja Petlja 4: 20 Ma
The 4 mA floor allows the system to distinguish between a "zero" reading and a broken wire (0 mA). 🛠️ Main Components A functional circuit consists of four essential parts: Sensor/Transducer: Measures the physical variable.
Two wires for power (+ and -) and one shared wire for the signal. shema tokovaja petlja 4 20 ma
A is the gold standard for analog signaling in industrial automation. It uses a constant current to transmit data from sensors to controllers (PLCs), offering high reliability over long distances. 💡 How It Works The 4 mA floor allows the system to
The system translates a physical measurement (like pressure or temperature) into a current signal between 4 mA and 20 mA. Represents the 0% or minimum value of the range. 20 mA: Represents the 100% or maximum value of the range. A is the gold standard for analog signaling
Current signals are less affected by electromagnetic interference (EMI) than voltage signals.
If you need a for a specific microcontroller like an Arduino or PLC.
