The LCA210 is a 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/output
isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by highly
efficient GaAIAs infrared LEDs.
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.
