Introduction

The 91-21SUBC/S400-A6/TR7 is a LED indication device. It is a type of discrete LED used to indicate the application field and working principle. This device includes a base unit and four LED displays of green, yellow, red and blue. The four LEDs in this device have a minimum current consumption of 5 mA and a maximum LED operational current of 15 mA. It also has an open circuit protection feature that prevents excessive current from entering the LED when there is no connection. The 91-21SUBC/S400-A6/TR7 is an excellent choice for applications that require precise control of LED visibility.

Applications

The 91-21SUBC/S400-A6/TR7 is widely used in a variety of application fields. It is especially well suited for outdoor use in harsh environments where visibility is essential and a high degree of reliability is required. It is ideal for both indoor and outdoor applications and is a perfect solution for applications such as airport signage, warning and emergency lights, automotive dashboards and displays, marine applications, traffic signals and highway bollard lights. In addition to its use in harsh environments, the 91-21SUBC/S400-A6/TR7 is also used in applications where precise measurement and control of LED visibility is required, such as laboratory testing and laboratory instrumentation. It is also widely used in industrial processes, providing accurate, reliable and highly visible results. This device is also an excellent choice for audio/visual applications such as music studios, recording studios, radio studios, sound and light shows, video production and theater sound systems. Its excellent visibility and precise control makes it perfect for these applications.

Working Principle

The 91-21SUBC/S400-A6/TR7 LED indication device uses a proprietary process to create the precise visibility required for its applications. This process involves charging a base unit that is connected to four LED displays: green, yellow, red and blue. When the base unit receives a signal, either by direct connection or by wireless transmission, it sends current to the LED displays. The current causes the LEDs to light up, giving an accurate and precise measure of the signal that has been received. The device includes an adjustable open circuit protection feature, which prevents excessive current from entering the LED displays if there is no external connection. This ensures that the LEDs always display a consistent level of brightness and are not overdriven by excessive current. The base unit also includes a power indicator to show when the device is switched on and when power is flowing to the LED displays. This provides a visual indication of when the device is in operation, which helps to diagnose any problems quickly and easily.

Conclusion

The 91-21SUBC/S400-A6/TR7 LED indication device is a reliable and trustworthy source of visibility and control. It is used in a wide variety of applications, from emergency lighting to laboratory instrumentation and professional audio/visual systems. The adjustable open circuit protection feature makes it ideal for both indoor and outdoor applications, and its power indicator makes it easy to diagnose any problems with the device. With its precise control and robust design, the 91-21SUBC/S400-A6/TR7 is an excellent choice for any application where precise control of LED visibility is required.
