0-10VDC Potentiometer: Understanding the Basics
A 0-10VDC potentiometer is a type of variable resistor that is used to control the voltage output of a circuit or device. In this article, we will explore the basics of 0-10VDC potentiometers, including how they work, their applications, and their advantages.
What is a 0-10VDC Potentiometer?
A 0-10VDC potentiometer is a type of potentiometer that produces a voltage output that varies between 0 volts and 10 volts DC (direct current). It is a three-terminal device, consisting of a rotary or linear shaft, a wiper, and two fixed terminals. The wiper moves along the resistive material, dividing the input voltage into two parts, which are then outputted through the two fixed terminals.
How Does a 0-10VDC Potentiometer Work?
A 0-10VDC potentiometer works by using the rotary or linear movement of the shaft to vary the resistance between the wiper and the two fixed terminals. When the shaft is turned or moved, the wiper moves along the resistive material, changing the ratio of the resistance between the wiper and the two fixed terminals. This, in turn, changes the voltage output of the potentiometer.
For example, if the input voltage is 10VDC and the potentiometer is set to the midpoint, the output voltage will be 5VDC. If the potentiometer is turned clockwise, the output voltage will increase, while a counterclockwise turn will decrease the output voltage.
