LN221RPH LED indication provides a discrete visible indication which is ideal for many applications in diverse industries.

Application Field

The LN221RPH LED indication is used across a wide range of industries, and is especially suited for the following applications:

• Industrial Automation
• Control Panels - visual indication of status of machinery
• Medical and Laboratory Equipment
• Drive Systems and Protection Systems
• Utility Equipment - lighting and power switching
• Lighting Boards - visual indication of status of panels
• Manufacturing Equipment - visual indication of failure or of level

Working Principle

The working principle of LN221RPH LED indication is based on the application of power to two transistors, one for each of two discrete outputs.

The circuits in the LEDs are connected to the logic pins on the LN221RPH and power is applied to the transistors.

When the logic pins are in their active state (ON), the power is applied to the corresponding transistors, providing the discrete visible indication.

The intensity of the LEDs can be adjusted to suit different environmental conditions and is dependent on the power feedback control in the transistors.

The LN221RPH provides a reliable and robust visual indication, with an excellent performance even under extreme temperatures.

It is extremely reliable and provides a long-lasting performance.

Conclusion

In conclusion, LN221RPH LED indication is an ideal solution for a wide range of applications, offering reliable and robust visual indication with excellent performance.
