The LCB127 is a 250V, 200mA, 10, single-pole,
normally closed (1-Form-B) Solid State Relay that
features enhanced peak load current capability. It
employs optically coupled MOSFET technology to
provide 3750Vrms of input to output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
This OptoMOS relay provides a more compact design
solution than discrete single-pole relays in a variety of
applications, and saves board space over conventional
electromechanical relays.
