Panel indicators – also known as pilot lights – are a type of visual indicator used on a wide variety of control panels and instrumentation assemblies. They are typically small in size and can be found on the front of control panels to alert an operator to the status of a system or process. Panel indicators can be used to indicate an action has been completed, a machine is malfunctioning or working properly, and more.

Application Field

Panel indicators are commonly used in a variety of industries and applications, including but not limited to industrial facilities, manufacturing plants, and even in medical devices. Whether it’s to alert an operator of a system malfunction, or to simply indicate when a process is complete, panel indicators are an energy-efficient and cost effective way of monitoring and controlling a system or process.

Working Principle

The working principle of panel indicators is relatively simple; when a system detects the need for indicating or signaling something, the panel indicator is triggered. This can be in the form of a light emitting diode (LED) or a lamp bulb. Once triggered, the panel indicator provides a visual indication to operators, such as a blinking light rather than an audible alarm. This means that the operator can be made aware of an issue even in noisy environments, or without the need for interruption. Panel indicators can also be used to signify when a system or process is functioning properly, such as turning a green light when the system is “idle”.

Panel indicator lights are typically powered by a low-voltage DC circuit, but can also be powered by an alternating current (AC) source. Some panel indicators are also capable of being mounted onto standardized electrical panels and using their own custom power source. In these cases, the panel indicator will typically use a matched resistor, meaning the system can be customized to the specific power source it’s connected to.

Some panel indicators also offer variable intensity control, allowing for brighter or dimmer lighting. This is useful in cases where an operator needs to be constantly aware of a system’s status. Panel indicators can also come with optional features, such as dimming or flashing, which help to alert operators to specific issues.

Panel indicators are a crucial part of maintaining a safe, efficient and effective system. When used correctly, panel indicators can alert operators to system issues or malfunctions quickly and without the need for interruption. With their low power consumption and simple operation, panel indicators are a cost effective and reliable way of monitoring and controlling a system or process.
