Solid State Relays

The semiconductor technology allows for the development of solid state relays, which, in contrast to electromechanical relays, do not contain any moving parts. The switching is purely electronic and therefore free of wear.
Solid state relays are increasingly replacing electromechanical relays in certain industrial sectors. This is especially the case for applications with a high number of switching cycles and high switching frequencies or for applications, where very rare yet very reliable switching is required.
