Solid State Relay (SSR) from TOWARD
Bright TOWARD provides variety of Semiconductor switch products from High Power Solid State Relay to defacto standard SIP/DIP packaged small Solid State Relay.
Solid State Relay (SSR) is Non-contacts relay constructed by semiconductor, often described in Semiconductor Relay vs Electromechanical Relay. There are two types of SSR, 1) Transformer-Coupled SSR and 2) Photo-Coupled SSR.
The control signal is applied through a DC-AC converter to the primary transformer, and the secondary is used to trigger TRIAC or MOSFET. In this type, the degree of input-output isolation depends on the design of the transformer.
The control signal is applied to a light or infrared source, and the radiation from that source is detected in a photosensitive semiconductor. The output of the photo-sensitive device triggers the TRIAC or MOSFET. In this type, input-output isolation is optically secured, and electrical isolation is excellent.
