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 3750V_rms 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.
