Panel Indicators and Pilot lights are devices designed to indicate when a particular system or machine requires human or technician intervention. This is done by adding visibility to a machine\'s working state. 305W-DRG120-O is the name of a type of panel indicator that is designed for a wide range of applications, the working principle of which is explained below in detail.

Overview and Applications

The 305W-DRG120-O is a panel indicator light intended to draw attention to the need for action on the part of an operator or technician. It is mainly used to indicate power on/off status, current alarms, and status changes of some equipment or devices. Examples of applications for this type of indicator include industrial automation, process control, equipment energy management, and instrumentation. The unit is rated IP30 for protection against dust and water and is suitable for use in moderately harsh environments.

Technical Specification

This panel indicator is designed with a robust construction for maximum reliability and durability. It is rated IP30 for protection against dust and water and is suitable for use in moderately harsh environments. The indicators are designed with a variety of LED lights available, including red, green, and yellow.

The 305W-DRG120-O is designed with an operating temperature range of -25°C to +60°C, and a dielectric strength of 250V / 0.3A. The maximum power consumption is around 0.5W. This panel indicator has a voltage range of 24V-0-24V, and the power connector is sized at 4mm pitch. Additionally, the mounting size of the indicator is 69mm x 69mm, and it can be connected with 2-core cable externally.

Working Principle

The 305W-DRG120-O panel indicators consist of four main components: housing, light source, switch, and feedback circuit. The housing is typically constructed of ABS material and is designed to protect the internal components from external environmental factors. The light source is typically an LED, which is installed inside the housing. The switch controls the current flowing through the light source, while the feedback circuit is used to control the brightness of the light source.

The working principle of the 305W-DRG120-O panel indicator is simple. When the switch is turned on, current flows from the power source to the LED. The current flows through the LED, causing it to emit light. The intensity of the LED light depends on the amount of current that is flowing through the LED, which is determined by the feedback circuit. When the switch is turned off, the LED light is turned off.

Conclusion

The 305W-DRG120-O is a panel indicator designed for a wide range of applications that require visibility to a machine\'s working state. The indicator is designed with robust construction for maximum reliability and durability. The four main components of this panel indicator are housing, light source, switch, and feedback circuit. The working principle of the indicator is quite simple and based on the flow of current through the LED light source.
