A device like a PLC or indicator that reads the signal, usually by passing the current through a 250 Ohm resistor to create a 1-5V drop for processing. 📐 Connection Types (Wiring Schemes) 2-Wire Connection (Passive)
Complete electrical isolation between power and signal. ✅ Why Use 4-20 mA? 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 A device like a PLC or indicator that
