The Siemens SIRIUS Series Blue Flashing Light Element model 8WD4420-5AF is a robust industrial beacon designed for automation and signalling applications. Featuring a vibrant blue LED bulb capable of continuous high visibility, this element is ideal for emergency signalling, machinery status indication, and process alerting in manufacturing, HVAC, and electrical systems.
With its versatile 24V AC/DC operation, the device integrates smoothly into a range of electrical infrastructures. Its IP65 protection ensures reliable performance against dust and water, making it fit for both indoor and outdoor environments, including situations where frequent washdown or exposure to elements is anticipated.
The blue lens and LED technology maximize visual impact, providing clear status communication with minimal power draw (maximum current consumption up to 30mA, typical 15mA). The LED's extended lifespan up to 100,000 hours supports continuous use with reduced downtime for bulb replacement, critical for industries aiming at high efficiency and system reliability.
Ergonomics and ease of installation are addressed by the bayonet fastening system, allowing prompt and secure mounting. The compact structure, with a height of 65.5mm and a base diameter of 70mm, is tailored for space-limited control panels and machinery enclosures.
Applications include emergency signalling on production lines, visual alerting in automation systems, status indication in process controls, and high-visibility notification in mechanical and electrical installations. The unit withstands operation in extreme temperatures from -20°C to +50°C and supports AC frequencies of 50Hz and 60Hz.
Certified to EAC and CE, the light element meets international standards for performance, durability, and safety. Its all-blue housing provides additional protection and ensures high recognizability in complex industrial environments.
This beacon is especially suited for sectors such as manufacturing, laboratory automation, construction, water treatment, and commercial electrical systems, supporting safety and operational monitoring.
