Calculator

Analog Scaling Calculator

Scale PLC raw input values into engineering units using standard linear interpolation for 4-20 mA, 0-10 V, and vendor-specific raw ranges.

Formula-backed output

Typed calculation logic is covered by focused tests and remains separate from the interactive 4-20 mA loop simulator.

Analog Scaling Inputs

Use raw counts and engineering limits from the card or PLC tag.

Engineering note

Confirm raw ranges against the exact card, module configuration, and signal type before commissioning. Different PLC platforms use different defaults and overrange behavior.
