What is HDSP-C3A3

HDSP-C3A3 display module is an LED character and numeric display system. HDSP is an abbreviation for Hexadecimal Seven Segment Display, meaning that it displays up to sixteen characters in six-digit, eight digit, and nine digit configurations. This display module is one of the most popular products offered by Hewlett-Packard, Inc. and has become a standard in the field of display modules.

Applications

HDSP-C3A3 LED display modules are used in a number of applications. They are commonly used in automotive and industrial control systems, allowing monitoring of multiple variables such as speed, temperature, and pressure among others. Their characteristics also make them useful in medical and laboratory equipment, where their robust design and compact form factor allow for easy integration into existing products. They are also used in professional measuring and monitoring devices, where their accuracy and reliability are critical.

Performance Specifications

The display module can operate within a voltage range of 9-18 VDC, and at a range of temperatures from -20°C to +85°C. Its luminosity can range from 0.5 mcd/sr to 40 mcd/sr depending on the viewing angle. HDSP-C3A3 can provide digital data via three parallel outputs.

Working Principle

The working principle of HDSP-C3A3 display module is based on the concept of hexadecimal seven segment display. This display module is composed of eight LED elements that can be used to represent up to sixteen characters. Each of the eight elements is made up of seven segments, which are connected in series. The eight segments, in combination with a conditioning circuit and a control unit, allow the module to input and output digital data.The control unit is responsible for controlling the current flow to each of the eight segments, depending on the digital data coded in hexadecimal format. The conditioning circuit transforms the digital data into a format suitable for the control unit. Then, the control unit adjusts the current flow to the appropriate segments for displaying the digital data in the form of characters.

Conclusion

HDSP-C3A3 is an LED character and numeric display module manufactured by Hewlett-Packard. This module is popular for its robust design and ability to display up to sixteen characters in a six-digit, eight digit, or nine digit configuration. Its wide range of applications include automotive and industrial control systems, medical and laboratory equipment, and professional measuring and monitoring devices. The working principle of this module is based on hexadecimal seven segment display and its operation is based on the control unit adjusting the current flow to each of the eight segments depending on the digital data.
