Panel Indicators

Panel indicators are normally used in process control, marine navigation and outdoor systems, and are usually identified by certain codes. P01-28B-2A is a panel indicator that falls into this classification, and it is commonly used for signal switching, alarm monitoring and regulation. It features a dual LED, which provides two different levels of quality and redundancy.

P01-28B-2A Application Field and Working Principle

P01-28B-2A panel indicators are commonly used in marine navigation, such as in buoys, in industrial applications and in vehicles for illumination, direction or control signals. In most applications, P01-28B-2A is used to indicate the presence or absence of a system\'s power, an alarm or an emergency condition.

P01-28B-2A works by using two separate light-emitting diodes, LED1 and LED2. LED1 is the brighter LED, and when illuminated, it indicates that system power is present. LED2 is a lower intensity LED, and when triggered it indicates an alarm or emergency is present. Both LEDs are usually either red or green in colour, and both are usually powered by 12V DC.

These LEDs can be triggered in a variety of ways. Depending on the application, they can be triggered by voltage, temperature or current. For instance, if the voltage rises or falls beyond certain levels, the LED will be triggered and illuminated. Similarly, if the temperature changes or the current increases beyond a certain amount, the LED will be triggered and illuminated. Otherwise, if all the conditions remain within acceptable ranges, both LEDs will remain off.

Pilot Lights

Pilot lights are also commonly used in process control, marine navigation and outdoor systems. They are used to provide visual feedback on the status of a system. For example, a green pilot light might indicate that the system is running normally, while a red one might indicate that an alarm has been triggered. Similarly, a blinking pilot light might indicate that the system is performing a task.

Pilot lights can be triggered in a variety of ways, similar to panel indicators. For instance, they can be triggered by voltage, temperature or current. Additionally, they can be triggered by mechanical or electrical switches that are activated by other devices. Pilot lights are usually powered by 12V DC, and they are commonly found in emergency lighting systems and in electrical fixtures.

In summary, P01-28B-2A panel indicators and pilot lights are commonly used in process control, marine navigation and outdoor systems. Panel indicators use two separate LED\'s to indicate the presence or absence of system power, an alarm or an emergency condition, while pilot lights provide a visual feedback on the status of the system. Both are usually powered by 12V DC, and they can be triggered in a variety of ways.
