5101H7LC

Introduction

5101H7LC is one of the panel indicators used in industrial control engineering. It is a light emitting diode (LED) display indicator with many advantages such as low cost, minimal power consumption, long life, and robust construction.

Application field

5101H7LC is primarily used in industrial control engineering for general indication and alarm systems. It is most suitable for applications that involve continuous operation such as process control and machine monitoring. It is also suitable for applications where instant visual feedback is required, such as alarm or limit operations.

The indicator is can be used in both hazardous and non-hazardous environments where its high quality, highly visible display is an essential requirement. The indicator is ideal for locations which require a safe and cost-effective alarm system.

Working principle

The 5101H7LC indicator is an LED-based display device. The indicator comprises of two parts: an LED and a transistor. The Transistor acts as a switch and is used to control the current flowing through the LED. The current in the LED is controlled by varying the voltage supplied by the power supply.

The LED is connected to a power supply via a resistor. The resistor limits the current through the LED and helps to protect the LED from damage due to overcurrent and overvoltage. The voltage across the LED determines the brightness of the light emitted by the LED. The LED is then connected to a transistor which is used to control the current in the LED.

When the transistor is turned on, it allows the voltage across the LED to increase, increasing the brightness of the light being emitted. When the transistor is turned off, the voltage across the LED is reduced, reducing the amount of light being emitted. This allows for an accurate and adjustable control of the brightness of the LED.

Conclusion

5101H7LC is an LED-based display indicator suitable for a wide range of industrial control engineering applications. It is easy to install and can provide a reliable and highly visible display with minimal power consumption. The working principle of the indicator is based on regulating the current through the LED with the help of a transistor, allowing for adjustable levels of brightness.
