LED Indication - Discrete: CMD2821VRCTR8T1 Application Field and Working Principle

LED technology is an electronic device that emits a light to indicate the state of an electronic circuit. It is widely used in many applications where a visual indication of the state of a circuit is needed, such as power and data transmission. CMD2821VRCTR8T1 is a discrete, bi-directional, multi-level LED indicator module. This module provides a range of functions that are suited to different applications.

Applications of CMD2821VRCTR8T1:

CMD2821VRCTR8T1 is typically used in automotive applications as indicators for power, circuits and data transmission. The module is ideal for applications that require multiple LED indicators, as it contains eight LED indicators with discrete bi-directional illumination indicating the current state of the circuit. The module is also an ideal solution for applications such as serial communications, machine control, and test and measuring instruments.

Working Principle:

The CMD2821VRCTR8T1 module consists of a central module and eight additional submodules. Each submodule consists of two LEDs: one is a bright red indicator and the other is a bright green indicator. When the module is in a non-active state, the LEDs are off, and when the module is in an active state, the LEDs will be illuminated in either a red or green color.The module uses an I2C interface to control the state of the LEDs. The I2C bus is a two-wire, bidirectional serial interface that is used to transmit digital information. The module is typically configured to enable either an active-high or an active-low control signal. When an active-high signal is applied to the module, the LEDs will be illuminated in the corresponding color; when a low signal is applied, the LEDs will be off.The module also contains an on-board voltage regulator, which allows for the use of a wide range of input voltages. The on-board regulator ensures that the output voltage remains constant, regardless of the input voltage. This feature ensures that the module can be used in a wide range of applications, regardless of the voltage tolerance of the system.

Conclusion:

CMD2821VRCTR8T1 is an ideal LED indicator module for many automotive applications that require a range of LED indicator functions. Its discrete bi-directional illumination and I2C interface make it easy to control and configure, while its on-board voltage regulator ensures that the module can operate in a wide range of input voltages. The module is therefore a great choice for applications that require multiple LED indicators.
