Description

The LCA210L is a current-limiting, common input, dual normally open (2-Form-A) solid state relay that has two independent MOSFET switch outputs controlled by a common input signal. It employs 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.

Common input OptoMOS relays can replace standard dual-pole relays in a variety of applications. The common-input relay eliminates the need to make an external circuit connection when both poles are controlled by a common signal.
