A solid state interface relay can be used to control electrical loads without the use of moving parts, but instead uses the electrical and optical properties of solid state semiconductor to perform its input to output isolation and switching functions.

### Why use a Solid State Interface Relay?

One big advantage a solid state relay has over a conventional electro-mechanical relay is there are no moving parts to wear out, and therefore no contact bounce issues. Interface relays are able to switch both ON and OFF much faster than a mechanical relays armature can move, as well as zero voltage turn-on and zero current turn-off, eliminating electrical noise and transients.

### Where can a Solid State Interface Relay be used?

Solid state interface relays are often used between a control system and a higher power load. Due to their versatility, compact sizing, and cost effectiveness they can be used in many different industrial applications such as motion, power, heating, and lighting control.
