0-10V scaling calculator
Convert the 0-10V output from an analog transmitter into the engineering value it represents (0–100 %, 0–10 bar, −40…+80 °C, and so on). Set the sensor minimum and maximum, then read the scaled result — or work backwards from a process value to the required voltage.
0-10V signal scaling
Formula: Result = Min + (Max − Min) × (V / 10). A 0-10V analog signal maps linearly: 0 V is the low end of span, 10 V the high end.0–10 V is the full span — valid signal is 0.0 to 10.0 V.
Reverse mode — voltage from process value
Formula: V = 10 × (val − Min) / (Max − Min), using the Min / Max above. Values outside the Min–Max span show “--”.
The scaled value is what a PLC or controller reads from the analog module on this channel. 0-10V is the other universal analog standard alongside 4-20mA — for the parts that read, transmit or isolate that signal — PLC analog I/O modules, 0-10V transmitters and signal isolators — browse AO Ctrl's industrial automation catalog:

Frequently asked questions
How do I convert a 0-10V analog signal into an engineering value?
The calculator applies Result = Min + (Max − Min) × (V / 10). With the default 0-100 scale, 0 V maps to 0, 10 V to 100, and every volt is 10 % of span — so 5 V reads 50. Replace Min and Max with your transmitter low and high engineering values (0-10 bar, −40 to +80 °C and so on).
What is the reverse formula to get the voltage for a given process value?
To work backwards from a process value to the required voltage the calculator uses V = 10 × (val − Min) / (Max − Min). Values outside the Min–Max span return no result, since a 0-10V signal cannot represent them.
Why does a 0-10V signal scale linearly across the sensor span?
The 0-10V standard maps the whole signal range onto the full sensor span: 0 V is the low end and 10 V the high end, so the relationship is a straight line. It is the other universal analog standard alongside 4-20mA used by PLC analog input modules, transmitters and signal isolators.
