PLC Analog Scaling Calculator

Pick a common signal type or enter your own raw and engineering ranges — drag the slider to simulate a live analog input.

How it works: Eng = (Raw − RawMin) / (RawMax − RawMin) × (EngMax − EngMin) + EngMin. Choose a preset to fill typical PLC ranges, or select Custom and type limits that match your tag configuration.
