TLHR4201 is a LED indication product that can provide discrete logic state through LED illumination. This product is used in various fields, such as vehicle control system, water and air conditioning systems, and home appliances. It has the advantages of easy installation, low power consumption, easy maintenance, wide range of applications, and long service life.

In terms of working principle, the TLHR4201has a built-in programmable logic circuit that can receive digital signals and convert them into separate logic signals. The logic signals are then sent to a LED display driver circuit to drive the LED display and provide the corresponding discrete logic state.

The LED display in the TLHR4201 adopts a 3mm LED equivalent dual circuit chip, which can display two genuine colors on one LED. The LED circuit is composed of two independent LED chips, one for the low voltage (L) circuit and the other for the high voltage (H) circuit. When one circuit is connected to the power supply, it will be illuminated. When the low voltage circuit of the LED is operated, the TLHR4201 will output the 0 logical state, and when the high voltage circuit is operated, the TLHR4201 will output the 1 logical state. This provides a very clear visualization which can accurately show the working state of various vehicle control equipment.

The TLHR4201 can also provide full control over the brightness of the LED display. The driver chip is connected to a brightness adjustment potentiometer, which can adjust the output brightness of the LED display by adjusting the current flowing through the LED display. This simple and accurate way to adjust the LED brightness also reduces the power consumption of the LED to make it more energy efficient.

TLHR4201 LED indication has a wide range of applications in vehicle control systems, water and air conditioning systems, home appliances, etc., due to its low power consumption, high accuracy, and easy installation. Its built-in programmable logic circuit can easily receive digital signals from the user and convert them into discrete logic signals to be displayed on the LED display. Through the control of the LED display brightness, it is possible to reduce the power consumption and make the device more energy efficient.
