1090A3-28V

Panel Indicators and Pilot Lights are devices used primarily for indicating the state of a machine or process to an observer. They are used in automated systems to display whether the system is operating as expected, or if there is a problem. 1090A3-28V is an example of such a device used in industrial applications. In this article, we will discuss its application field and working principle.

Application Field

The 1090A3-28V is a combination two-color (red/green) panel indicator/pilot light used in a variety of applications. It is used most often in industrial settings, such as manufacturing plants and warehouses, to monitor and indicate the status of a process or machine. The indicator features a low-profile lens, making it easy to see in a variety of lighting conditions. The 1090A3-28V is also UL listed, making it a safe and reliable option for industrial applications.

Working Principle

The 1090A3-28V is a two-color indicator that uses a dual light source to indicate different states. The device consists of two LEDs – one red and one green that are positioned behind a lens. When the device is in the “on” position, both LEDs emit their respective colors at full intensity, resulting in a yellow appearance. When the device is in the “off” position, the red and green LEDs are turned off, resulting in a black appearance.

The 1090A3-28V uses two separate circuits for powering each LED, with each circuit controlled by separate switches. When one switch is in the “on” position, the corresponding LED turns on, while the other LED remains off. When both switches are in the “on” position, both LEDs are turned on, creating a yellow appearance. In addition, the device can also be wired for momentary functions, and can easily be used in conjunction with other types of indicators, such as buzzers or alarm lights.

Conclusion

The 1090A3-28V two-color panel indicator/pilot light is a useful device for indicating the state of a process or machine in an industrial setting. It is easy to install and is UL listed for safety. It is powered by two separate circuits, allowing it to indicate different states with a single device. It is also versatile, allowing it to be used in conjunction with other types of indicators or alarms.

Overall, the 1090A3-28V is a reliable and convenient option for industrial settings that require an indicator of state or process. It is easy to install and comes with a variety of features that make it a stable, safe, and versatile option for a variety of applications.
