1116-R48-CW

Panel Indicators, Pilot Lights

Panel indicators and pilot lights are integral components of any safety-certified electrical system, signaling the presence of a hazard or alerting a user to a particular condition of a system. The 1116-R48-CW application field and working principle are the topics we will cover in this article.

What is the 1116-R48-CW?

The 1116-R48-CW is a universal type pilot light that is designed for hazardous area applications, such as those encountered in the petrochemical industry and explosion proof environments. It features a 20mm diameter illumination area, which is brightly illuminated by an LED. The lens face is curved to eliminate potential glare to the user. The 1116-R48-CW is equipped with two LEDs, one amber and one green, and can operate anywhere between a standard 0 and 127V AC/DC voltage range.

Application Field

The primary application field of the 1116-R48-CW is in hazardous areas where special design considerations must be taken to protect personnel and equipment. This includes areas such as refineries, chemical and petrochemical plants, and other explosion-proof areas. It is a robust, universal pilot light that can be used in a variety of applications.

The 1116-R48-CW is UL approved for lighting hazardous areas, Class 1, Div 1 and Div 2, and is also ATEX and IECEx certified. Additionally, it is designed with a heavy duty construction that ensures durability and long-term performance.

Working Principle

The 1116-R48-CW utilizes two LED modules, one amber and one green, that illuminate a 20mm area. The LEDs are wired internally, eliminating the need for external wiring. The LEDs are activated either directly or through an LED Control Module, depending on the application.

The LED modules are connected to a power source, usually a 110V AC, and create an electric current. As the current passes through the LED modules, the LEDs brighten and emit light. The light is then transmitted through the lens face of the indicator, which is curved to eliminate glare. This process illuminates the 20mm area, signaling the presence of a hazard or alerting to a particular condition of the system.

Conclusion

The 1116-R48-CW is a universal type pilot light that is designed for hazardous area applications, such as those encountered in the petrochemical industry and explosion proof environments. It features a 20mm diameter illumination area, which is brightly illuminated by an LED. It utilizes two LED modules to produce an electric current that illuminates the 20mm area, signaling the presence of a hazard or alerting to a particular condition of the system. It is UL approved for hazardous areas, and is also ATEX and IECEx certified.
