I=4mA+(16mA×P)cap I equals 4 m cap A plus open paren 16 m cap A cross cap P close paren Example: At 50% capacity, the loop should read . If you are designing a specific circuit, let me know: The sensor type you are using. The distance between the sensor and the controller.

Handles power-hungry sensors (e.g., gas detectors). 4-Wire Connection (Fully Isolated)

If you need a for a specific microcontroller like an Arduino or PLC. shema tokovaja petlja 4 20 ma

Easy to troubleshoot with a standard multimeter. 📊 Conversion Math To calculate the current ( ) for a given percentage of the range (

Two wires for power (+ and -) and one shared wire for the signal. I=4mA+(16mA×P)cap I equals 4 m cap A plus

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

Converts the sensor signal into the 4-20 mA current. Handles power-hungry sensors (e

Can run hundreds of meters without signal loss (unlike voltage, which drops over distance).
