Solid state relay

Solid state relays can be divided into DC solid state relays (DCSSR) and AC solid state relays (ACSSR) according to the output mode. According to the switch form, they can be divided into two types: normally open type and normally closed type. DC, constant current DC and AC types, according to the output rated voltage, there are two types: AC voltage (220-380V) and DC voltage (30-180V).
