The LCA210 is a common-input, dual normally open
(2-Form-A) solid state relay that has two MOSFET
switch outputs controlled by a single input signal. It
employs optically coupled MOSFET technology to
provide 3750Vrms of input/output isolation.

Features
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by highly
efficient infrared LEDs.
• Greater Reliability than Electromechanical Relays
• FCC Compatible
• VDE Compatible
• No EMI/RFI Generation
• Small 8-Pin Package
Common-input OptoMOS relays can replace standard
dual-pole relays in a variety of applications. The
common-input relay eliminates the need to make a
second external circuit connection when both poles are
controlled by a common signal.
