The MY4NJ Power Relay is a versatile electromagnetic switching component designed for industrial control applications and electrical automation systems. This general-purpose relay features a 4PDT (4 Pole Double Throw) configuration, providing four normally open and four normally closed contacts that enable complex circuit control and multiple switching operations from a single device. The silver alloy contacts are rated to handle 5A at 240V AC or 5A at 28V DC, making it suitable for controlling motors, lighting systems, heating elements, and other electrical loads. Available with multiple coil voltage options including AC 12V, 24V, 110V, and 220V at 50Hz/60Hz, this relay offers flexible integration into various control systems. The transparent blue housing allows visual inspection of the internal mechanism, while the built-in LED indicator provides clear confirmation of the relay's operational status. With 14 pins and compatibility with standard 35mm DIN rail mounting, installation is straightforward in electrical enclosures and control panels. The compact dimensions of approximately 1.3 x 1.1 x 0.8 inches make it space-efficient for panel layouts. Engineered for reliability, this relay delivers an electrical life exceeding 100,000 operations and operates effectively in temperatures ranging from -13°F to 131°F. The action time of less than 25ms ensures responsive switching performance for time-sensitive applications.
