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

The sensor has its own dedicated power source (often AC or high-voltage DC). shema tokovaja petlja 4 20 ma

Easy to troubleshoot with a standard multimeter. 📊 Conversion Math To calculate the current ( ) for a given percentage of the range ( Complete electrical isolation between power and signal

Handles power-hungry sensors (e.g., gas detectors). 4-Wire Connection (Fully Isolated) Easy to troubleshoot with a standard multimeter

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 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.
