Typically 24V DC to drive the current through the loop.
Handles power-hungry sensors (e.g., gas detectors). 4-Wire Connection (Fully Isolated)
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.
Easy to troubleshoot with a standard multimeter. 📊 Conversion Math To calculate the current ( ) for a given percentage of the range (
