The MY4NJ Power Relay is a versatile electromagnetic switching component designed for industrial control applications and automation systems. This compact relay features a 4PDT (4 Pole Double Throw) configuration, providing four normally open and four normally closed contacts for complex circuit control. With silver alloy contacts rated at 5A 240V AC or 5A 28V DC, this relay delivers reliable switching performance and an impressive electrical life exceeding 100,000 operations. The transparent blue housing allows visual inspection of the internal mechanism, while the built-in LED indicator provides instant confirmation of relay status during operation. Available in multiple coil voltage options including AC 12V, 24V, 110V, and 220V at 50Hz/60Hz, this relay adapts to various power supply configurations. The 14-pin design mounts easily on standard 35mm DIN rails, making installation in control panels straightforward. Measuring approximately 1.3 x 1.1 x 0.8 inches and weighing just 2.6 ounces, this relay offers professional-grade performance in a space-efficient package. The relay operates reliably across temperatures from -13°F to 131°F with an action time of less than 25ms, ensuring responsive switching for time-sensitive applications.
