The FM4MMA116M5 is a reed relay module with 4 mechanical relays, designed to provide high input current, no contact leakage, low driving power, high contact capacity, and long life. It has wide application fields with excellent features.

Application Field
The FM4MMA116M5 is primarily used for signal switching applications in areas such as electric power telemetry, electrical inspection, and home automation. With its mechanical relays, it is suitable for the control of large current and voltage and can switch high power electromagnetic loads. In addition, it is widely used for the conversion and transmission of AC/DC electrical signals.

Working Principle
The FM4MMA116M5 works by using electromagnetism. When the control signal is on, a DC voltage is applied to the coil, generating an electromagnetic field and magnetizing the core in the coil. The reed relay uses the magnetic field to attract the plunger, adjusting the contact switch and completing the circuit. When the current is cut off, the plunger restores its original position, and the contact switch separates and returns to its original state.

The FM4MMA116M5 has the advantages of high input current, no contact leakage, low driving power, high contact capacity, and long life. Therefore, it is widely used in various fields such as electric power telemetry, electrical inspection and home automation. With its excellent features, it will provide great help to signal switching applications.
