In addition to general-purpose pilot lights, the 2390 qdx4-28v also comes in a wide variety of industry-specific and hazardous-location models, making it well suited for different applications and work environments.

2390qdx4-28v Panel Indicators and Pilot Lights offer reliable illuminated indication for power, machine status, fault condition, failure and more. The state of the indicator can be changed with a single switch, push button or even a PLC.

The 2390qdx4-28v panel indicators and pilot lights feature a variety of voltages and wattages, as well as robust housing to protect from shock and vibration. They are UL rated and feature either incandescent or LED light sources. The LED models are energy-saving and more efficient.

Working Principle

The working principle of 2390qdx4-28v Indicators and Pilot Lights is based on the process of power supply. The power supply to the indicator causes the electrons in the indicator to move through the filament, thereby causing a light reaction and producing the light. LED-illuminated indicators and pilot lights have a different form of power supply. LEDs use an internal semiconductor element that applies electricity to the light source, which then produces light.

The 2390 qdx4- 28v Panel Indicators and Pilot Lights can be wired in different ways, depending on the installation and the type of indicator or pilot light. Generally speaking, common DC wiring involves wiring the positive and negative terminals to obtain the correct polarity. AC wiring involves the use of a transformer to convert the power to the correct voltage and frequency.

The 2390qdx4-28v panel indicator and pilot lights are designed to be installed in hazardous locations, such as hazardous area class I and II divisions and groups. Class I hazardous locations require explosion proof enclosures while class II hazardous locations require intrinsically safe enclosures. The 2390qdx4-28v indicator and pilot lights are designed to meet the National Electrical Code and other applicable standards for hazardous locations.

The 2390qdx4-28v panel indicators and pilot lights can be used for a wide range of applications, including industrial, medical, transportation, and military. The indicator and pilot light can be used to indicate if a machine is on or off, if equipment has been turned on or off, or if there is a malfunction or fault. They can also be used for security and fire alarm systems, or to signal the status of a process or system.

The 2390qdx4-28v Panel Indicators and Pilot Lights are designed to provide reliable and efficient illuminated indication in many applications. They feature a variety of voltages, wattages, and robust housing to protect from shock and vibration. They are UL rated and feature either presilled or LED light sources. The LED models are energy-saving and more efficient, making them ideal for hazardous location applications.
