This F5-D2 mini time delay relay auxiliary contact block is an essential component for precision timing control in electrical circuits. Designed to work seamlessly with contactors, this compact relay provides off-delay timing functionality ranging from 0.1 to 30 seconds, allowing you to control when circuits de-energize after the main contactor switches off. The space-saving design makes it perfect for installations where panel space is at a premium, while still delivering reliable performance. This auxiliary contact block features both normally open (NO) and normally closed (NC) contact configurations, providing flexibility for various circuit requirements. The clearly marked dial allows for easy time adjustment, and the robust construction ensures long-lasting operation in demanding industrial environments. CE certified for compliance with international safety standards, this relay is suitable for a wide range of applications including motor control, lighting systems, HVAC equipment, and automated machinery. The straightforward mounting system enables quick installation directly onto compatible contactors, streamlining your setup process and reducing installation time.
