Units
V
The LCA210L is a common input 1-Form 2A solid
state relay which has two independent optically cou-
ple MOSFETS controlled by a common input signal.
The efficient current limiting MOSFET switches and
photovoltaic die use Clare’s patented OptoMOS®
architecture to provide 3750 VRMS of input to output
isolation. The optically coupled input is 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 com-
mon signal.
