LED indicating and setting is a familiar API in modern electronic displays. LED Discrete applications are usually used for indicating the relative status, showing the feedback of a process and providing the option for connecting analog and digital signals. The application field and working principles of the HSMD-C150 LED indicator and settable are described in this article.

Overview of the HSMD-C150

The HSMD-C150 is an LED discrete indicator and settable designed by Laird Technologies and manufactured in China. It features a mechanical 30mm high x 12mm wide indicator and a 28V transistor-transistor logic (TTL) compatible line driver. The HSMD-C150 is designed for easy integration into existing projects and can be used for a wide range of applications, such as test and measurement, industrial automation, process control, security, and so on.

Features of the HSMD-C150

The HSMD-C150 boasts several features that make it suitable for a wide range of applications in LED indication and setting. It has an LED indicator and a TTL compatible line driver IC. The LED indicator has a LED brightness of up to 10mcd, a low current consumption of 330µA, a wide operating temperature range of -20°C to +70°C, and a 12V voltage drop. Moreover, the LED indicator has a lifespan of up to 50,000 hours, so it can be used for extended periods of time. Additionally, its line driver IC has a low-level output current of 0.7mA, a high-level output current of -3.0mA, and a switching frequency of up to 25MHz.

HSMD-C150 Application Field

The HSMD-C150 is suitable for numerous discrete LED applications, from simple LED indications and setting to more complex tasks such as displaying warning messages and providing feedback from a process. It can also be used to inform the user of the current system status, such as a low battery warning. Moreover, it can be used for industrial automation and process control. In addition, the HSMD-C150 can be used to connect analog and digital signals for displaying the changing environmental data or providing feedback to a control system.

HSMD-C150 Working Principle

The working principle of the HSMD-C150 is quite simple. The LED light is connected to the line-driver IC, and when a voltage is applied to the input pin, the current is diverted to the LED and it illuminates, indicating the status. The TTL input is connected to the output of a logic circuit or an analog signal, and when an input is applied on the logic pins, the line driver activates the LED, illuminating or setting it accordingly. When the input is removed, the current is diverted from the LED, turning it off.

Conclusion

The HSMD-C150 is a versatile LED discrete indicator and settable designed for a wide range of operating conditions. It features an LED indicator with a life expectancy of up to 50,000 hours, low current consumption of 330µA, and a 12V voltage drop. Moreover, it has a line driver IC with a low-level output current of 0.7 mA, a high-level output current of -3.0 mA, and a switching frequency of up to 25 MHz.
