solid-state relay
Solid-state relay (SSR) is a new type of contactless switching device composed of solid-state electronic components. It can make use of the switching characteristics of electronic components to make and break the circuit without contact and spark, so it is also called "contactless switch". It has the functions of amplification and isolation, and is very suitable for driving high-power switching actuators. Compared with electromagnetic relays, it has higher reliability, no contact, long service life, high speed and little interference to the outside world, and has been widely used in household appliances and industrial automation products.

optical relay
Light relay is a semiconductor relay with AC and DC, which is an integrated device of light-emitting device and light-receiving device. The input side and the output side are electrically insulated, but signals can be transmitted by optical signals. Optical relay has the advantages of no mechanical contact, long service life, low operating current, high isolation voltage, high speed switching and low leakage current, and is mainly used in measuring equipment, communication equipment, security equipment and medical equipment.
