Geheugenrelays

Geheugenrelays, also known as latching relays or remanent relays, are a type of electromechanical switch that maintains its last position even after the control signal is removed. Unlike conventional relays that require continuous power to stay in a particular state, geheugenrelays use a mechanical latching mechanism or a permanent magnet to hold the contacts in place. This means they consume power only when switching between states, making them energy-efficient for applications where the state needs to be maintained for extended periods.

There are two main types of geheugenrelays: single-coil and double-coil. Single-coil relays use a pulsed signal to change the state. A pulse in one direction sets the relay, and a pulse in the opposite direction resets it. Double-coil relays use two separate coils, one for setting and one for resetting. When a pulse is applied to the set coil, the relay moves to the set position, and the coil can then be de-energized. Similarly, a pulse to the reset coil moves it to the reset position.

Geheugenrelays are employed in various applications, including power systems for switching control, battery-powered devices where energy conservation is crucial, and in automation systems where maintaining a state without continuous power is desirable. Their ability to retain their last position without consuming power makes them suitable for applications like remote switching, status indication, and in situations with unreliable power supplies. The selection between single-coil and double-coil designs often depends on the control system's capabilities and the desired switching logic.
