Shema Tokovaja Petlja 4 20 Ma < Validated – BLUEPRINT >

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

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. 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 powered by the loop itself. Two wires carry both power and the signal. Benefit: Saves cable costs and simplifies installation. 3-Wire Connection (Active) If you need a for a specific microcontroller

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

Two wires for power (+ and -) and one shared wire for the signal. Represents the 0% or minimum value of the range

The sensor has its own dedicated power source (often AC or high-voltage DC).
