Analog Scaling: Converting 4–20 mA Signals Into Real-World Values
Many industrial sensors output a 4–20 mA signal, but your PLC can’t use that directly — it needs to convert the raw current into real-world units like °C, bar, or millimeters.This conversion process is called analog scaling, and getting it right is essential for accurate alarms, trends, and control logic. How Analog Scaling Works A…
