305-ALP2-O Application Field and Working Principle

The 305-ALP2-O is an LED panel mounted indicator specifically designed for process industries. The indicator has a sealed, robust polycarbonate enclosure making it resistant to high pressure through-wash-down and dirt. It is suitable for hazardous and hygienic industrial environments where long life, easy installation and operation are critical.

The 305-ALP2-O is suitable for use in a variety of applications and it has several features that make it well suited for these applications. It is rated for operation from -25°C to +50°C, has a rated voltage range from110 VAC to 240 VAC and a rated current range from 0.05 A to 0.2 A. The 305-ALP2-O also has an integrated buzzer and can be used to sound an audible alarm when necessary.

Working Principle

The 305-ALP2-O is a two-wire LED panel indicator that is designed to operate by simply connecting it to a power source. The LED indicator changes color when it is connected, depending on the type of panel indicator. Green LEDs indicate power is present, red LEDs indicate power is off, and yellow LEDs indicate intermediate values.

The 305-ALP2-O can be configured for different operating parameters allowing it to be used in various applications. For example, the hysteresis value can be set allowing the indicator to trigger a change in the LED color at a set level. The timer function can be adjusted to ensure the LED changes color for a specific amount of time before returning to its previous status.

The 305-ALP2-O can also be configured to work with external switches or sensors, allowing for remote indication of the status of the process. This feature makes the 305-ALP2-O suitable for many process automation applications.

Conclusion

The 305-ALP2-O is an LED panel mounted indicator with a rugged, sealed polycarbonate enclosure that is suitable for hazardous and hygienic industrial applications. It features adjustable parameters and can be configured to work with external switches or sensors. This makes the 305-ALP2-O very reliable and well suited for a variety of applications in the process industries.
