0-10V Potentiometer Circuit: A Comprehensive Guide
Introduction
A 0-10V potentiometer circuit is a type of electronic circuit that utilizes a potentiometer to produce a voltage output that varies between 0 and 10 volts in response to the rotation of a shaft or knob. This circuit is commonly used in industrial automation, process control, and other applications where precise voltage control is required.
How it Works
A 0-10V potentiometer circuit typically consists of a potentiometer, a voltage source, and a load resistor. The potentiometer is a three-terminal device that consists of a resistive material and a wiper that moves along the resistive material as the shaft or knob is rotated. The voltage source is connected to the two ends of the resistive material, while the load resistor is connected to the wiper and the output terminal.
When the potentiometer is rotated, the wiper moves along the resistive material, dividing the voltage source into two parts. The voltage across the load resistor is proportional to the position of the wiper, and the output voltage varies between 0 and 10 volts as the potentiometer is rotated from one end to the other.
