LEDs, or Light Emitting Diodes, are tiny semiconductor devices which convert electrical current into light energy. They come in a variety of sizes and colors, and offer numerous advantages over traditional lighting for a variety of applications. LED indicators are one type of LED which, when connected to an electrical system, send out a visual signal to indicate the status of a system or process.

The 91-21SUGC/S400-A4/TR9 LED Indicator is a discrete LED indicator specifically designed for this purpose. It is a red light-emitting diode often used in household appliances such as washing machines, refrigerators, and dishwashers. It is also used in automotive electronics and in medical diagnostic devices. This particular model has a standard lens diameter of 16mm, a current rating of 1A, a working voltage of 2V and a power dissipation of 0.2W.

The 91-21SUGC/S400-A4/TR9 LED Indicator is a general-purpose indicating device that functions by providing a sudden and visible warning in a wide range of potential applications. As long as the right voltage is applied, the LED will be activated, emitting light. This light can be used for status notifications, system alerts, alarms and even for basic directional guidance. By using this versatile indicator device, users can easily monitor signals from a range of inputs, processes or operations.

The 91-21SUGC/S400-A4/TR9 LED Indicator is designed to work within an overall system. It is connected to the system with a terminal block, and the source feed runs through the terminal blocks. When activated, the LED emits a steady, flashing or intermittent light, depending on how the system is configured. This is used to indicate the current status of the system or a specific event or process within the system.

The 91-21SUGC/S400-A4/TR9 LED Indicator is not only efficient and reliable but also economical. A single LED can be used to indicate a wide range of system parameters, lowering the cost of the total system. Furthermore, the LED\'s low current consumption allows it to be powered by a small battery, or even off a solar cell. This makes it ideal for use in remote locations or in situations where space and power are limited. The LED\'s long life span, up to 100,000 hours, ensures that the device will not need to be replaced frequently.

The 91-21SUGC/S400-A4/TR9 LED Indicator is a great way for system designers to communicate state information to their users. By quickly and concisely relaying system parameters and events, the LED Indicator is an invaluable tool for system operations, maintenance and troubleshooting. It is especially useful for non-experts as it provides a simple visual indication of the system\'s activity, allowing users to quickly identify when something is wrong without needing to understand complex electrical wiring or programming.
