Industrial-grade solid state relay is a four-terminal device with
two terminals as input terminals and the other two terminals
as output terminals. An isolation device is used in the middle to
achieve electrical isolation between input and output.
Industrial-grade solid state relays can be divided into AC type
and DC type according to the type of load power supply.
According to the switch type, it can be divided into normally
open type and normally closed type. According to the isolation
type, it can be divided into hybrid type, transformer isolation
type and photoelectric isolation type, with the photoelectric
isolation type being the most.
