Introduction

SA56-21YWA is a LED character and numeric display module featuring a 6-digit display, typically used to provide the user with feedback. It features a background illumination, low power consumption and wide temperature range, making it an ideal solution for a variety of applications.

Application Field

SA56-21YWA can be used for a variety of applications, including:

• Electronic display boards
• Industrial & process control systems
• Test and measurement instruments
• Medical instrumentation
• Security control systems

It is also widely used in commercial applications, such as advertising displays, timers, alarm clocks, remote monitoring systems and educational display systems.

Working Principle

The working principle of SA56-21YWA is based on the use of LEDs to produce an illuminated display. A single board consists of a series of 6 LEDs, each connected to a current limiting resistor. The connections between LEDs are brought to the two sides of the module, where they can be wired to external circuits.

The module is powered by two external power sources. The voltage for the LEDs is provided by a DC power source, while the power for the background illumination is provided by an AC source. When the module is connected to an external circuit, the LEDs are illuminated, producing a 6-digit display.

The module also contains a control circuit, which is connected to the LEDs via a serial data bus. This bus provides the module with the necessary inputs for controlling the LED display. The data is transmitted in a serial fashion, and can be changed or updated as required.

In addition to its 6-digit display, the SA56-21YWA also features an additional two-digit position. This can be used to display additional information such as time, date and temperature, making it an ideal solution for applications requiring more than just the standard digit display.

Conclusion

The SA56-21YWA is a highly versatile LED display module, suitable for a wide range of applications. It features a 6-digit display, background illumination and low power consumption, making it an ideal solution for a variety of applications.
