LED Indication - Discrete

The FR1111C-2005-TR is a commonly used LED indication device, which is typically used to signal when a device is in a “ready” state or when it is in use. This type of LED indication is especially useful in situations where the user needs to be able to quickly glance at the LED to know the ready state or active state of a device.

Application Field

The FR1111C-2005-TR is found in numerous applications, from industrial and medical equipment, to consumer products and appliances. It is particularly well suited for use in systems where reliability is critical, as it offers a bright, long lasting indicator. Also, as an LED-based indicator, it is not vulnerable to failure by overvoltage or transient voltage spikes, as with an electromechanical solution.

Working Principle

The FR1111C-2005-TR works by illuminating an LED when the device is “ready” or in use. This is done by connecting the LED to a power source, usually through a bias resistor. The resistor acts as a current limiting device to prevent the LED from burning out due to over current. The LED is connected to a voltage source through a transistor, allowing the LED to be activated by simply applying a signal to the transistor’s base.

The FR1111C-2005-TR can also be designed to work with a wide variety of signal types and voltages. The device requires only a simple signal, such as a logic signal or a control voltage, in order to operate, and can work with signal voltages up to 24 Volts. Additionally, the transistor used in the device is temperature stable, ensuring long life and reliable performance.

Conclusion

The FR1111C-2005-TR is a versatile, reliable and inexpensive LED indication device. It offers a simple, easy to use solution for many applications where visibility of a “ready” or “active” state is desired. It is capable of working with a wide variety of signals and voltages, making it an ideal choice for a broad range of applications.
