NL589H3R Optoelectronics

The NL589H3R belongs to a group of industrial signaling devices known as panel indicators, pilot lights, and alarm notification devices. These devices share a common theme of providing visual or auditory indicators to alert personnel of equipment status or system needs. In addition to traditional on/off signaling capabilities, the NL589H3R also offers more sophisticated control and diagnostic functions. Developed by ESU, a leading innovator in the industrial signaling field, NL589H3R panel indicators employ a variety of technologies to provide versatile and reliable feedback in demanding industrial settings.

Types of NL589H3R Panel Indicators

The NL589H3R is available in several models to meet the needs of a variety of applications. The NL589H3R-W is a universal wide-angle multi-functionally illuminated type panel indicator. The NL589H3R-V is a standard size panel indicator with built-in signal output for remote operation. The NL589H3R-G is an optional green illumination type. The NL589H3R-R is a red illumination type.

Technical Specifications of NL589H3R Panel Indicators

The NL589H3R panel indicators feature a universal design with a small footprint, making them suitable for use in a variety of control panels. The indicator features a plug-together wiring construction, making it easy for installation and maintenance. The 0.47" OD LED status light has an 1/4" hub for quick connection. The NL589H3R is rated for 10A at 250V AC and is approved by UL, CSA, and CE. The weight of the NL589H3R is approximately 1.5 oz.

Working Principle of NL589H3R Panel Indicators

The NL589H3R panel indicators work on a principle known as On-Delay and Off-Delay. On-Delay works as a timer for the panel indicator to remain lit for a certain amount of time when the power is first switched on. This ensures that personnel takes notice of the status of the equipment even if the switch is only briefly turned on. The Off-Delay feature allows the panel indicator to remain lit until after the switch has been turned off for a certain period of time. This provides a visual indicator of the amount of time that the equipment has been off.

Applications of NL589H3R Panel Indicators

The NL589H3R panel indicators can be used in a variety of industrial applications. It can be used as an indicator of machine status in factory automation, or as a warning light for hazardous or critical equipment. The NL589H3R can also be used as a tool in diagnostics and troubleshooting operations. The NFEM5930 is a patented stability system, which utilizes the NL589H3R indicators as part of its self-diagnosis operations, allowing the system to automatically detect and analyze potential anomalies.

Conclusion

NL589H3R panel indicators are robust, reliable, and versatile industrial signalling devices that can be used in a variety of applications for different purposes. Their on-delay and off-delay features make them particularly suited for diagnostics and troubleshooting operations. Whether it is as a warning light for hazardous equipment or as a tool for automated self-diagnosis, the NL589H3R is a valuable addition to any industrial setting.
