Panel indicators, pilot lights, and other visual warning devices can be necessary tools for many industrial and consumer applications. From basic on/off indicators to complex multi-colored systems, visibility is the key factor. The NL2951WL2R is a two-color LED unit that can be used for a wide range of applications. This unit is an ideal fit for customers who require reliable and highly visible indications on their control and monitoring panels.

Product Specifications

The NL2951WL2R is a panel-mounted LED warning unit with two distinctive colors. The unit features a dual-level indicator, and both levels can be adjusted depending on the application. The maximum current ratings are 5mA per LED. One level can be programmed to display a green light, while the other can be programmed to display a red light. The operating temperature for this unit ranges from -55°C to +85°C.

Installation and Operation

The NL2951WL2R is easy to install. The unit consists of a main body, two securing pegs and an LED module. The connection between the main body and the LED module is simple: the two pegs on both sides of the LED module slot into the LED slots on the main body. The secured LED module is then held in place with two screws. The whole process should take no longer than five minutes.

To operate the NL2951WL2R, three connections have to be made. The first connection is between the ac voltage source and the ground. The second connection is connected to the input signal voltage, and the third connection connects the two LEDs in series. Once all three connections are established, the NL2951WL2R is ready for operation.

Working Principle

The NL2951WL2R works by converting the input voltage into an appropriate current ratings. The incoming signal voltage is transformed into two distinct current levels – one for the green LED and the other for the red LED. The two current levels are then individually regulated so that the LEDs display a consistent brightness. Both LEDs will light up simultaneously if the input voltage exceeds the threshold level. The input voltage is then regulated so that the green LED stays on and the red LED turns off.

Application Field

The NL2951WL2R can be used in numerous applications. Areas that are especially suited for its use are industrial control and monitoring panels. This warning unit is especially helpful in those situations where it is not practical to use audible alarms, for example, in environments that have a high level of background noise. The NL2951WL2R is also popular for warning signs, as the dual-color system provides an easily recognizable indication of important information. This unit can also be used for automotive, medical and security panels.

Conclusion

The NL2951WL2R is a versatile LED warning system that can be used for numerous industrial and consumer applications. The unit’s dual-color feature is particularly useful for providing visual cues and warnings in noisy environments. This warning system is easy to install and is suitable for use on control and monitoring panels, automotive, medical and security panels, etc. The NL2951WL2R is suitable for use in most standard circuits and can be used to provide a reliable and highly visible indicator of activities and alarms.
