Applications and Working Principles of LTD-571Y

Introduction

The LTD-571Y is a display module used primarily in mechanical and electrical equipment, typically in industrial and commercial sectors. It is sold as a module or in a kit with the necessary components such as signal drivers, power supplies and connectors. Its main features are its 2.45” height, 4.43” wide and 0.2” depth; four digit display; built-in RS232 driver, TTL In/Out; 500V DC/AC isolation protection; support for total of 24 different baud rates from 75 up to 115200; and bright LED character displays.

Applications

The LTD-571Y is a perfect fit for production line equipment, operating conditions and functions. It is ideal for applications that require the display of a user-defined four-digit data, including numerical values such as production environment temperatures, production time, unit counts, and alarms. The module is also suitable for instruments used in various industries/sectors such as medical instrumentation, automobiles and office machinery.

Working Principle

At its core, the LTD-571Y display module is comprised of a four-digit display coupled with a x-y positioner control. This combination enables the module to display single or multiple digits of information at any given time. The module uses an RS-232 serial port to accept digital command and data inputs from a host system, which enables it to process the received information and display it using the four-digit LED character display elements.The LTD-571Y is regulated by power logic output signals from an external interface via a TTL In/Out line, which is driven by TTL-level logic signals from a host system. This TTL-level logic is converted to an analog signal via a switching element that then serves as an input for the x-y positioner control. The x-y positioner control then determines which LED elements will be activated for the display of a given set of data.

Conclusion

The LTD-571Y is an ideal display module for applications that require a high-contrast, bright LED numerical display. Its flexibility and reliability make it suitable for use in a wide range of mechanical, electrical and industrial applications, thus providing users with an unprecedented level of convenience and ease of use. Its compact design also enables it to be integrated into a variety of host systems without the need for large, bulky components.
