Introduction

The VLMD31L2N1-GS18 is a discrete LED indication device. It provides reliable visual indication in a wide range of applications. It is used for indication in control and instrumentation panels, instrumentation, voltage signals, and other industrial applications.

Application Field

The VLMD31L2N1-GS18 is a discrete LED indication device. It is primarily used in instruments, voltage signals, and other industrial applications. It is designed to provide a visible sign of real-time error or the input\'s current state. It can also be used to provide a wide range of status information such as ON/OFF, voltage level, speed, and other parameters.

Working Principle

The VLMD31L2N1-GS18 is based on a transistor-transistor logic (TTL) system. It works on the basis of the “brown-out” principle. When the input voltage drops, the device produces an output signal. This signal triggers the LED and turns it on. When the voltage returns, the device shuts off the output and extinguishes the LED. The VLMD31L2N1-GS18 is also equipped with a built-in latch. This latch prevents the device from turning on again after the brown-out has occurred.

Features

The VLMD31L2N1-GS18 is capable of handling low current level inputs with high noise immunity and immunity to electromagnetic interference (EMI). Its operating voltage range is from 0.8V to 5V and the input S-parameters are V DD /GND=5V/0V. It is also equipped with a current limiter function and an error output indicator. Furthermore, the VLMD31L2N1-GS18 is designed to be used in extremely sensitive applications, in hazardous locations, and in applications where long-term stability is required.

Conclusion

The VLMD31L2N1-GS18 is a discrete LED indication device that provides reliable visual indication in a wide range of applications. It is based on a transistor-transistor logic system that works on the basis of the “brown-out” principle. It is capable of handling low current level inputs with high noise immunity, and it is also equipped with current limiter function and an error output indicator. This makes it suitable for use in extremely sensitive applications, in hazardous locations, and in applications where long-term stability is required.
