Panel Indicators and Pilot Lights

Panel indicators and pilot lights are pieces of electrical hardware used in industrial, commercial, and military applications. They are typically mounted to control panels and indicate the status of devices by means of visual signals. The type of panel indicator or pilot light used depends upon the application.

34-ALP12H-NWO application field and working principle

The 34-ALP12H-NWO panel indicator is an LED pilot light that is designed for use in hazardous industrial and commercial environments. It is constructed from polycarbonate and brass material and is capable of withstanding temperatures up to 185°F. The 34-ALP12H-NWO is suitable for use in Class I, Division 1, and Class I, Zone 0 hazardous areas. It is UL recognized and approved for wet locations.

The 34-ALP12H-NWO is powered by a 120V/230V AC primary source and will operate at a frequency of 50/60Hz. It has a rated load of 0.44 amps and a maximum wattage of 10W at 2200V. The frequency should not exceed 2Khz. The steady indicator features an LED light bulb functioning as a visual indicator. The indication element is a 12V neon bulb which turns on when energized. The integrated heatsink ensures the LED bulb does not overheat and function correctly.

Installation of the 34-ALP12H-NWO is on a mounting base or panel and all the connections should be made in accordance with the wiring diagram. Once installed, the indicator can be tested by switching the power on and off. The LED indicates when the power is on and the neon bulb lights up when the power is off.

The 34-ALP12H-NWO panel indicator is an easy-to-install, reliable indicator that is ideal for hazardous environments. It is a cost-effective solution for indicating the power status of a machine or system in a hazardous area. The LED and neon indicators make it easy to determine when the power is on or off, and its robust construction ensures safe and reliable operation in hazardous situations.
