LED (Light-Emitting Diode) indication is an increasingly popular type of electronic indicator due to its robustness, energy efficiency and aesthetically pleasing design. The QBLP651-S1 is an especially versatile example of LED indication, due to its various functions and wide range of applications. In this article, the application field and working principle of the QBLP651-S1 will be discussed.

The QBLP651-S1 is a type of two-channel, discrete LED indicator for power switches, and is commonly used in pumps, motors, and water valves. Its main application field is to indicate the state of the power switch to the user, making it possible to tell when the switch is turned on or off without having to manually check the device. Additionally, it can also be used to indicate operating temperature, and when a device is functioning properly.

The QBLP651-S1 is designed with a series of discrete LED\'s that are each connected to the output of a power switch. Each LED is designed to emit different colors depending on the state of the power switch, with one LED indicating the “on” state, and the second LED indicating the “off” state. This two-color indication makes it convenient for the user to tell whether the switch is turned on or off. Additionally, the QBLP651-S1 measures operating temperature, and can be configured to indicate when the temperature is too high or low. Examples of this temperature indication include red for “dangerously hot” and blue for “safe”.

The working principle of the QBLP651-S1 is relatively simple. It utilizes a double-throw power switch that is connected to the LED\'s discrete outputs. Depending on the state of the power switch, the LED\'s will either be illuminated or remain unlit. For example, when the switch is turned on, the LED connected to the switch will be illuminated, while the LED connected to the switch’s “off” state will remain unlit. Similarly, when the switch is turned off, the second LED will be illuminated, while the first LED will remain unlit.

The QBLP651-S1 is an effective and efficient example of LED indication. Its wide range of functions and applications make it an ideal choice for a variety of devices. Its ability to indicate the state of a power switch, as well as measure operating temperature, makes it a versatile and reliable piece of technology.
