Description
PLA191 is a single-pole, normally open (1-Form-A) solid state relay that uses optically coupled MOSFET technology to provide 5000Vrms of enhanced input to output isolation.
Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient GaAIAs infrared LED.
