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)
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) A device like a PLC or indicator that
