PC applications have become one of the most important components of industrial facilities. The PC application field is comprised of a wide variety of different applications, such as panel indicators, pilot lights, and more. This article will focus on the PC application field and its working principle.

Panel Indicators

Panel indicators are small, light emitting diodes (LEDs) typically used to display the status of a device or system. Panel indicators can either be single or multi-colored LEDs that are mounted on a panel or flat surface with a variety of different circuit arrangements. A typical panel indicator has a single LED surrounded by a variety of different lenses and bezels in order to diffuse the light emitted from the LED. Panel indicators can be used for everything from indicating whether a device is powered on or off to providing a warning that a critical piece of equipment is approaching the end of its operational life.

Pilot Lights

Pilot lights are very similar to panel indicators, yet have a few key distinguishing features. Firstly, the size of a pilot light is typically larger than a panel indicator and it uses a more powerful LED, usually a 3–5 watt LED. Secondly, unlike panel indicators that use individual lenses and bezels, pilot lights most commonly use a single reflector to diffuse and direct the light. Additionally, pilot lights are often used to indicate the status of an alarm system or automate system process.

Working Principle

The working principle of the PC application field can be broken down into two parts: the control system and the display system. The control system consists of a variety of different components, such as sensors, relays, and switches, that can activate or deactivate the system. The display system is comprised of the indicators or pilot lights themselves, which are connected to the control system in order to display the status of the system. For example, if a panel indicator is connected to a relay, then it can be used to display the status of the relay – whether it is open of closed. In this way, panel indictors or pilot lights can be used to give visual indications of the status of a system or process.

In conclusion, PC applications are an important part of any industrial facility. Panel indicators and pilot lights are two common components of the PC application field, and their working principle can be broken down into a control system and a display system. By using sensors, relays, switches, and other components, the control system can activate or deactivate the system, while the indicators or pilot lights are used to display the status of the system to the operator.
