• Extended operating life up to 10 million cycles

Working Principle

The RV8H-2L-AD12 power relay is a type of electromechanical relay that uses an electromagnetic field to attract and hold an armature inside the relay to switch between two circuits. When an electrical current is applied to the coil of the relay, a magnetic field is generated, which moves the armature to make contact between two separate circuits. When the current is removed, the armature is released and returns to its original position, which breaks the connection between the two circuits. This is known as a “break before make” switch, which ensures that, while the relay is changing between two circuits, there is never any overlap in connections and no risk of overloading.

This type of relay is particularly suited to applications like safety systems, motor starters, and alarms, where immediate switching is important. It is also used in high power medical equipment applications, which require a reliable switching device that can handle high voltages and currents.

Conclusion

The RV8H-2L-AD12 is a power relay designed for a wide variety of applications that require reliable switching and control. It is capable of handling up to 2 amps of current and offers contact switching and superior contact life. It also provides an optically isolated interface and a wide voltage range, making it the ideal choice for applications requiring high current and voltage switching. The working principle of the RV8H-2L-AD12 is based on a break before make mechanism, which ensures reliable switching and no overlaps in connections.
