Panel Indicators and Pilot Lights

Panel indicators and pilot lights are electrical components used to indicate the status of a given system, usually in response to signals received from switches, sensors and controllers. The primary purpose for these components is to provide an easy-to-read visual indication for operators, maintenance personnel and other users. They are used in a variety of applications, from production process monitoring and error message identification, to system status display.

Application Fields

Panel indicators and pilot lights are used in a variety of fields, including:

• Industrial: These components are commonly used in industrial machinery, such as milling machines and other automated machines. They are also used in PLC systems and other process control systems, such as SCADA.
• Building Automation: These pieces are also used in many building automation systems, such as heating and cooling systems, ventilation systems, security systems, and other environmental control systems.
• Medical: In the medical field, these components are typically used to monitor and display vital statistics such as blood pressure, heart rate, pulse oximetry, and other vitals.
• Aviation: Panel indicators and pilot lights are also used in aircraft, such as fuel gauges, warning lights, and engine status.
• Transportation: These components are also used in the railway industry, such as in trains, buses and other vehicles. They are also used in many types of boats and ships.
• Office Equipment: In office equipment, equipment such as copiers, printers, scanners, and fax machines use these components to display status and control settings.

Working Principle

Panel indicators and pilot lights typically operate by way of an electric signal, such as a voltage or current. When a given voltage or current is detected, the LED or other indicator will light up. A given LED may require a positive or negative voltage, depending on the type of diode used. The color of the LED may also vary depending on the type of voltage or current supplied. Typically, a higher voltage results in a brighter or more intense color. The current limit resistor is an important component for controlling the brightness of the LED. In some instances, different colored LEDs can be used to indicate different conditions. For example, red may indicate an active system, while green may indicate a standby or spooled system. A separate electronic circuit may be used to control the operation of the LEDs. Pilot lights typically use incandescent bulbs, rather than LEDs. These bulbs are typically cheaper and are often used when a more visible indication is needed. Such applications would include machinery monitoring and control and building automation. In conclusion, panel indicators and pilot lights are used to provide a visible indication of the status of a given system, whether for monitoring, control, warning or other reasons. Different colors can be used to indicate different states for a given system, and incandescent bulbs and LEDs can be used depending on the required illumination intensity.
