Single-Pole, Normally Closed OptoMOS® Relay

Manufacturer's part number :


Manufacturer UK_IXY_SI


Description :

LCB111 is a 350V, 120mA, 35ohms, 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.
