Description

The LCA20-2A1E473MT is a common input 1-Form 2A solid state relay that features two independent optically coupled MOSFETS controlled by a common input signal. It utilizes Clare's patented OptoMOS architecture to provide 3750 VRMS of input to output isolation. With highly efficient GaAIAs infrared LEDs, the LCA20-2A1E473MT is capable of replacing standard dual pole relays in a variety of applications, eliminating the need for external circuit connections when both poles are controlled by a common signal.
