NL276WL2A is a panel indicator with a pilot light. It is typically used in industrial applications for visual indication of process, product, equipment statuses or alarms. This model combines the visibility of a dual-state pilot light with a full scale bar indicator that can be used for applications that require a more accurate indication.

Design

The NL276WL2A is designed with a high visibility dual state pilot light indicating either off, on, or flashing, a full scale bar graph, and a high contrast wide angle display window that create a visual signal useful for multiple-state or range indication of process, product, or equipment statuses, or an alarm. It is designed with modular construction that allow quick and easy customizations from one unit to multiple units without rewiring.

Operation

The NL276WL2A panel indicator is powered by a 12VDC to 24VDC voltage source and has a current operating range of 0.2–2.0A. It operates on most of the standard industrial control voltages and provides three working illumination sources for the pilot light: red illumination (R), green illumination (G), and yellow illumination (Y). The pilot light illumination is designed with a current limiting resistor in the circuit to protect the LED from over-current, voltage overload, or short circuit. The adjustable sensitivity range of the bar graph allow for a wide range of operation.

Installation and Maintenance

The NL276WL2A can be mounted on a panel or any other surface with the use of standard mounting hardware. It has two mounting holes at the back and four mounting holes at the front, allowing for quick and easy installation. The maintenance of the unit requires regular cleaning to reduce dust buildup and extend the life of the LED. It is also important to check the components and make sure they are properly connected.

Applications

NL276WL2A panel indicator can be used in a variety of industrial applications including process control, product maintenance, equipment monitoring, and alarm systems. It is designed for easy installation and operation, making it an ideal choice for applications where accuracy and visibility are required. It is also suitable for areas that require lighting without the need for hazardous high voltages.
