LCB111
Single Pole, Normally Closed
OptoMOS® Relay
Description
LCB111 is a 350V, 120mA, 35ï—, normally closed
(1-Form-B) solid state relay featuring high sensitivity.
It uses optically coupled relay technology to provide
a 3750Vrms isolation barrier between the input and
the output of the relay.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
The LCB111 can be used to replace mechanical
relays, and offers the superior reliability associated
with semiconductor devices. Because it has no moving
parts, it can offer faster, bounce-free switching in a
more compact surface mount or thru-hole package.
