LED Indication - Discrete

LEDs have grown in popularity in the last decade due to their high efficiency, long operating life, and small size. They offer an inexpensive, efficient alternate to traditional lighting. Additionally, LEDs can be easily integrated into new applications.

The LTL-4222 is a discrete LED indicator designed specifically for a wide range of industrial applications. It is a single-wire device that provides a means of active state indication. This device is commonly used in various electrical control systems, and is built to be reliable and economical.

Application Field of LTL-4222

The LTL-4222 is designed for industrial use and can be used in a variety of environments. It is especially well-suited for applications where a definite active state indication is needed. The device is highly resistant to many industrial conditions, including:

• High temperatures up to 90°C (194°F)
• Exposure to vibration, shocks and mechanical obstacles
• Humidity, dust and dirt
• Chemical, gas and oil fumes
• Rapid changes in temperature

The device is also dust and water-resistant, making it a great choice for outdoor and wet environments. Additionally, the LED is available in a variety of colors, which can help convey different operational statuses.

Operating Principle

The LTL-4222 LED indicator is a discrete device with a simple operating principle. The device is designed to be powered from a wide range of signals, including AC, DC and PN. This input is typically used to turn the LED on/off, or to activate certain effects such as flashing or fading. When the input is on, the LED will light up, and when it is off, the LED will remain off.

The device has been designed to be highly efficient and can provide up to 20mA of current. This current may be applied to the LED to make it brighter, which is beneficial in applications with reduced lighting. Additionally, the device has an integrated resistor, which can help reduce power consumption and increase stability. In some cases, an external driver may be used to reduce power consumption even further.

The operating voltage of the LTL-4222 is typically 3.3V to 24V DC, although other input voltages can be used depending on the application. The device is also designed to be highly reliable and can handle up to 10 million cycles. This makes it a great choice for applications that require long-term reliability.

Conclusion

The LTL-4222 is a single-wire discrete LED indicator designed for a wide range of industrial applications. The device is highly resistant to vibration, shock, and temperature changes, and is dust and water-resistant. The device is powered from a variety of signals, and can provide up to 20mA of current. The device is also highly reliable, and can handle up to 10 million cycles.
