Introduction

LED Indication is a type of display technology that utilizes the visible wavelengths of light to transmit information. Discrete LED indication is an efficient way of communicating various types of information in a variety of ways, from simple status updates or alarms, to displaying a full range of values and instructions. The CMD93-21VRC/TR8 is a discrete LED Indicator Module that is used to display different states and values. This article provides an in-depth overview of the application field of the CMD93-21VRC/TR8 and discuss its working principle.

Application Field

The CMD93-21VRC/TR8 is a discrete LED Indication Module designed to provide a visual and audible display of various statuses and values. The module is mainly used in the industrial and consumer market.In the industrial field, the CMD93-21VRC/TR8 is commonly used in manufacturing and laboratory equipment. The module\'s ability to display multiple values with a single LED indicator makes it perfect for monitoring production lines and testing areas. It is also often used as a status indicator, with built-in audible alarm capabilities, making it ideal for industrial automation systems that need to alert operators to potential issues.In the consumer market, the CMD93-21VRC/TR8 is used for a variety of purposes such as monitoring of home appliances, lighting controls, and digital entertainment systems. The flexibility of the discrete LED Indicator Module makes it ideal for these applications, as it can be easily integrated into existing systems and provide a visual display or audible alerts.

Working Principle

The CMD93-21VRC/TR8 consists of eight individual LED indicators and an audio transducer. When the module is powered, DC current passes through the LED indicator and its associated resistor and triggers the light-emitting diode to light up. With the electrical circuit between the LED and its resistor, a given amount of current flows which is determined by the value of the resistor. This allows the brightness of a single LED indicator to be adjusted through the changing of the current flowing through the circuit.The audio transducer of the module is a device used to convert electrical signals into sound. It consists of a flat disc composed of various materials and is typically driven by voltage or current to vibrate and produce sound. In the CMD93-21VRC/TR8, the audio transducer receives a signal from a PID controller or similar device, which sends a signal whenever it detects a change in a monitored parameter. The sound produced by the transducer acts as an audible alarm that can alert users to changes in the system.

Conclusion

The CMD93-21VRC/TR8 is a discrete LED Indicator Module that is commonly used in industrial and consumer markets to provide a visual and audible display of various statuses and values. Its eight individual LED indicators, combined with its audio transducer, make it an ideal choice for applications where accuracy and reliability are of utmost importance. The working principle of the CMD93-21VRC/TR8 is primarily based on the flow of current through its LED indicators and audio transducer, making it a highly efficient and reliable discrete LED indication solution.
