Description
PBB190 is a dual single-pole, normally closed
(1-Form-B) solid state relay with two independently
controlled switches that use optically coupled
MOSFET technology to provide 5000Vrms of input to
output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
Dual single-pole OptoMOS relays provide a more
compact design solution than discrete single-pole
relays in a variety of applications by incorporating
both relays in a single 8-pin package.
