CMD15-21VRC/TR8

LED Indication - Discrete, is an important and wide application field in electronics engineering, industry and commercial application. CMD15-21VRC/TR8 is one of the best discrete LED indicators and it can be used for wide range of indicating applications.The CMD15-21VRC/TR8 can be used for indicating application with many different work procedures. Its basic underlying principle is based on switching circuit theory, which controls LED through a single resistor when application with LED as the indicator. This LED indicators are designed to perform various types of tests, ranging from circuit integrity testing to blackout detection.One of the first and most important features of the CMD15-21VRC/TR8 is that it is prototyping friendly and can be used in different sizes of small debugging and verification environments. The CMD15-21VRC/TR8 has a single LED indicating section, which is extendable and will not only brighten your working environment, but also gives you the visuals you need without having to resort to any other auxiliary appliances.The CMD15-21VRC/TR8 LED indicator is also equipped with a set of special sensing forces, which ensures that the LED indicator accurately displays the status at any time, just like the laboratory normal circuit level indication. Furthermore, the CMD15-21VRC/TR8 is designed to be able to provide a more direct indication for many applications like circuit DC warning, overheat alarm and fault detection.The working principle of the CMD15-21VRC/TR8 is very simple and is based on the principle of turning off the current by selecting one of the seven resistors in the range from 1 ohm to 128 ohms. Selecting one of these resistors will place the corresponding current through the base-emitter section of the transistor and the base-collector section will then be active, thus turning off the current. This is the basic principal of these discrete LED indicators.In addition to displaying status, the CMD15-21VRC/TR8 can also detect the fault and malfunction of the circuit and can be used for warning in applications which require test functions. The detection of a fault occurs when the voltage applied to the transistor is not in the desired range and this will then cause the LED to indicate that the circuit is malfunctioning.Last but not least, the CMD15-21VRC/TR8 discrete LED indicators are easy to install and maintain and will provide a cost effective option for indication projects. The device is flexible in terms of mounting options, being able to be available in a variety of sizes and colors, depending on the user’s requirements.CMD15-21VRC/TR8 discrete LED indicators are an ideal choice for applications which require stable and reliable indication due to their robust nature and toggle switch which allows for quick and easy comparison of grouped indicator values.
