LED Indication - Discrete

LED (Light Emitting Diode) technology is found in many forms and shapes now. LED indication has been widely used in various industries to indicate the indication state and flow of processes. In a distributed automation system, there are lots of types of indication devices which form a complete monitoring system. One kind of indication device is a type of visible indicator called Remote 3-Color-Hue Discrete (R3HD).

Application Field of R3HD

R3HD is a signal indicating device used in distributed monitoring system. It is composed of multiple high brightness LED lamps and signal processing circuit for high accuracy indication. With its slim design and high brightness, it is widely used in various indications such as production process indication, diagnostic indication, process flow indication, system status indication and other industrial field indication.

It has an extremely wide application range and can be used in a variety of industrial fields like automotive, electronics, electric power, petrochemical, manufacturing and chemical processing. In these industries, products and processes are often complex and difficult to understand. R3HD can provide a graphical display of the status of processes and products, which allows operators to make better decisions.

Working Principle of R3HD

R3HD works by combining multiple high brightness LED lamps with signal processing circuit for high accuracy indication. It can be used in a variety of ways, such as a single-color display or a multicolor display.

As a single color display, R3HD receives a single color input signal and then displays the signal by turning on the LED lamps of the same color. For example, when receiving the input signal of green color, the LED lamps of green color will light up, which means that the receiving signal is normal. Conversely, if the LED lamps of different colors light up, it means that there is something wrong with the input signal.

In terms of multicolor display, R3HD receives a three-color input signal, which can control the LED lamps to light up in three different colors, such as green, red and yellow. This indicates that three different states are received, such as normal operation, warning and danger.

R3HD is equipped with a signal processing circuit in order to convert signals into corresponding indications. When a signal is received, this circuit can convert signals into indications and then control the light on/off state and frequency of the LED lamps.

Conclusion

R3HD is a remote 3-color-hue discrete indicator which is widely used for industrial process indication, system status indication and other industrial field indication. It is composed of multiple high brightness LED lamps and signal processing circuit for high accuracy indication.

R3HD can display the signal by turning on the LED lamps in different colors. As a single color display, it receives a single color input signal and then displays the signal by turning on the LED lamps of the same color. As a multicolor display, it receives a three-color input signal and then control the LED lamps to light up in three different colors.

Through signal processing circuit, R3HD can convert signals into corresponding indications, thus providing a graphical display of process state which allows operators to make better decisions.
