Typically 24V DC to drive the current through the loop.

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) 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 Typically 24V DC to drive the current through the loop

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) It uses a constant current to transmit data

Converts the sensor signal into the 4-20 mA current.

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.
