QLMP-LM78-34CDD

QLMP-LM78-34CDD is a type of LED indication module used in discrete applications. It is equipped with a LED on the module, which works as the indicator. This LED can be used to indicate whether a specific circuit is functioning properly or not.

The module is usually found in industrial applications, where high precision signals are sent from one circuit board to another. It is also beginning to be found in home automation and Internet of Things applications as more and more people adopt these technologies.

The working principle of the module is relatively simple. It is based on a low voltage difference between the two pins connected to the module. When voltage difference is lower than the threshold determined by the module, the LED on the module will illuminate. This action is used to indicate whether a specific circuit is functioning properly.

The module is usually powered by direct current. This is to ensure that there is a constant current flow between the pins, making it easier to detect the voltage difference. The LED on the module typically works at 12 volts. This means that another voltage source is required if the voltage between the two pins is lower than 12 volts.

In some cases, the LED on the module is used to indicate the presence of a specific signal. For example, in an industrial setting, if a specific signal is sent from one board to another, the LED will be illuminated, giving a visual indication to the user that the signal has been received. This is a useful feature, as it allows the user to quickly determine whether a signal has been received or not.

The QLMP-LM78-34CDD module is useful in a wide variety of applications. It can be used to indicate the status of a specific circuit, or as an indicator for the presence of a specific signal. Its low voltage operation and LED illumination make it ideal for many discrete LED indication applications.
