IntroductionPanel Indicators and Pilot Lights are a type of electrical switch used to indicate, control or visually give feedback on the status of a machine or system. Typically, they provide a visual indication as to the status of the system and will display an end-user-defined color or flash sequence depending on the machine or system state. The P81W-G120-CG is an example of a Panel Indicator and Pilot Light used in industrial machinery. This article covers the application field and working principles of the P81W-G120-CG.Application FieldThe P81W-G120-CG is an LED panel indicator and pilot light designed for use in industrial applications. It is a single circuit LED indicator with ampere operating tolerance range from 3.0A to 2.0A rated. It is suitable for various installation types such as 3-phase systems, single phase systems, motor or generator control panels, UPS systems, energy and power distribution centers, etc. The P81W-G120-CG meets all IEC requirements for safety and reliability.The P81W-G120-CG has a colored light lens, an external resistor and various SMD or through-hole mounting options. It has a green light lens and is available in 8mm, 12mm, 16mm and 22mm sizes. It features a high intensity LED with brightness of up to 700mcd, and a uniform beam angle of approximately 120° for clear view of the indicator state. The indicator also contains surge protection up to 1,500V, and its operating temperature range is -20°C to 70°C.Working PrincipleThe P81W-G120-CG uses a wide range of input voltage: from 6V to 240V AC/DC. When the input voltage is within the specified range, the LED indicator will light up, regardless of the current flow or the polarity of the input voltage. When the input voltage is outside the allowable input voltage range, the LED indicator will not light up.The P81W-G120-CG indicator and pilot light can be activated by a switch or a relays. When a switch or relay has been activated, it will send a voltage to the LED indicator, which in turn will activate the LED and indicate the state of the system. The LED indicator can also be used with a variable resistor to adjust the intensity of the light.The P81W-G120-CG is designed to protect circuits against high voltage by using a built-in surge protection device. The on-board surge protection will limit the current flow through the indicator and act as a switch, preventing the indicator from being damaged by high voltage.ConclusionThe P81W-G120-CG is a Panel Indicator and Pilot Light is designed for industrial applications, providing a visual indication of the system status. It is a single circuit LED indicator with an operating tolerance range from 3.0A to 2.0A rated, and is suitable for various installation types. The P81W-G120-CG LED indicator uses a wide range of input voltage and is protected against high voltage surges by a built-in surge protection device.
