Rotary Potentiometers and Rheostats are two related components that are commonly used in various electronic applications. Both components have the same underlying working principle, but they serve different purposes and are used in different types of applications. In this article, we will take a look at the REL200 application field and working principle.

What is REL200?

REL200 is a rotary potentiometer made by the brand REED. It is a three-terminal resistor that is used to control the voltage and/or current in a circuit. The REL200 has a rotating shaft, and by adjusting the angle of the shaft, the resistance value is changed. It is available in a number of sizes, including a popular 12mm diameter version. It is commonly used in motor controllers, feedback systems, logic gate control, and LED dimmers.

Working Principle

The REL200 is a single-layer rotary potentiometer, which uses three terminals. One of these terminals is connected to the voltage source, while the other two are connected to the output terminals. When the shaft of the potentiometer is rotated, the resistance value between the two output terminals is varied, which in turn affects the voltage and/or current in the circuit.

The main advantage of the REL200 is its ability to control the voltage and/or current in the circuit without affecting the power dissipation. This is achieved because the power dissipated is determined by the resistance value of the potentiometer, and the amount of power dissipated is same regardless of the position of the shaft.

Applications

The REL200 is commonly used in motor control, feedback systems, and logic gate control. It is also used as a variable resistor to regulate the current or voltage in a circuit. It is used in LED dimmers, as it can control the brightness of the LED.

Other than these applications, the REL200 is also used in various other applications, such as adjustable voltage regulators, transistors, and amplifiers. It is also used in audio processing applications, where it is used to adjust the frequency response of a certain sound system.

Conclusion

The REL200 is a three-terminal rotary potentiometer. It works on the same principle as a rheostat, but it is used for different applications. It is used in motor controllers, feedback systems, logic gate control, and LED dimmers. It is also used in audio processing applications to adjust the frequency response.

The main advantage of the REL200 is its ability to control the voltage and/or current in the circuit without affecting the power dissipation. Thus, it is widely used in various electronic circuits.
