1090C5-28V

Panel Indicators, Pilot Lights

A 1090C5-28V is a type of panel indicators and pilot lights, which are commonly used to provide visual feedback for signal outputs in industrial or commercial applications. They help differentiate power output levels, signal status, or different conditions from other circuits. 1090C5-28V panel indicators and pilot lights are designed for use in enclosed control panels, industrial and marine environments, and OEM applications.

Application Field

1090C5-28Vpanel indicators and pilot lights are typically designed for applications with higher voltage and current levels. These signals are often located in enclosures and may be used to indicate high or low power levels, AC field strength, or potential failure and caution scenarios. Additionally, the 1090C5-28V panel indicators and pilot lights may be used to identify the location and status of various circuit components such as reset switches, auxiliary switches, and actuators.

Working Principle

The 1090C5-28V panel indicators and pilot lights primarily operate by converting input signal voltages to visible LEDs. The indicator light contains an internal LED circuit that emits visible light when it receives an electrical current from a power source. To achieve this, the indicator light contains a light source that typically consists of an LED diode and a voltage regulator. The voltage regulator provides a constant voltage to the LED diode that is regulated by the input voltage. Additionally, the light source is usually connected to an externally powered circuit, such as a DC power supply, for operation.

Most 1090C5-28V panel indicators and pilot lights are designed with an on/off feature; when the input voltage is applied, the voltage regulator turns on the LED diode, causing the signal to emit visible light. It is also possible for a device to be designed with a variable brightness feature, which allows the user to adjust the brightness of the LED diode. In addition, these signals are often sealed to resist dust and moisture, making them suitable for use in wet or humid environments.

Another important function of 1090C5-28V panel indicators and pilot lights is the ability to protect against overloads. Many devices are designed with an overload protection circuit that limits the current flow to the LED diode. This circuit also protects the LED circuit from damage. In the event of an overload or voltage surge, the overload protection circuit will shut off the current to the LED diode, preventing the LED diode from being damaged.

In summary, 1090C5-28V panel indicators and pilot lights are essential components in signal output applications. They are designed for environments with higher voltage and current levels. The LED circuit inside the light emits visible light when an input voltage is applied, and is often sealed for dust and moisture resistance. The overload protection circuit prevents LED damage and helps keep the device functioning properly.
