Description
LCA220 is a common-input, 250V, 120mA, 20, dual normally open (2-Form-A) solid state relay that has two independent, optically coupled MOSFET switches controlled by a common input signal. It is provided in an 8-pin package, and 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 the same signal.
