Used when the sensor requires more power than the 4 mA baseline can provide.

Two wires for power and two separate wires for the 4-20 mA signal. shema tokovaja petlja 4 20 ma

If you need a for a specific microcontroller like an Arduino or PLC. Used when the sensor requires more power than

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 A is the gold standard for analog signaling

The most common setup where the transmitter is powered by the loop itself. Two wires carry both power and the signal. Benefit: Saves cable costs and simplifies installation. 3-Wire Connection (Active)

Complete electrical isolation between power and signal. ✅ Why Use 4-20 mA?

Current signals are less affected by electromagnetic interference (EMI) than voltage signals.
