Description
LCA125L is a current-limiting, 300V, 170mA, 20, normally open (1-Form-A) solid state relay that uses optically coupled MOSFET technology to provide 3750Vrms of input to output isolation.
Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient GaAIAs infrared LED.
