Convert a 4-20mA signal to engineering units, or work backwards from a value to the milliamp or raw-count it represents. The scaling is linear: EU = EU_min + (input - input_min) × (EU_max - EU_min) / (input_max - input_min). Pick your card type (4-20mA, 12-bit 0-4095, Allen-Bradley 15-bit 3277-16383, 16-bit, or a custom raw range), and the calculator flags NAMUR NE43 under- and over-range faults on a real current loop.
