Shema Tokovaja Petlja 4 20 Ma ⚡ Updated

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)

Can run hundreds of meters without signal loss (unlike voltage, which drops over distance). shema tokovaja petlja 4 20 ma

Handles power-hungry sensors (e.g., gas detectors). 4-Wire Connection (Fully Isolated) The most common setup where the transmitter is

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 3-Wire Connection (Active) Can run hundreds of meters

If you need a for a specific microcontroller like an Arduino or PLC.

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

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