20 Ma - Shema Tokovaja Petlja 4

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

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

Handles power-hungry sensors (e.g., gas detectors). 4-Wire Connection (Fully Isolated) Used when the sensor requires more power than

If the wire snaps, the current hits 0 mA, immediately triggering a "fault" alarm. the current hits 0 mA
