LBA127L comprises two independent 250V, 150mA,
15 solid state relays: one current-limited,
single-pole, normally open (1-Form-A), relay and one
single-pole, normally closed (1-Form-B) relay.
The relay outputs are constructed with efficient
MOSFET switches and photovoltaic die that use
Clare's patented OptoMOS architecture, while the
inputs, highly efficient GaAlAs infrared LEDs, provide
the optically coupled control.
LBA127L is designed to provide an ideal solution
where a complementary Form-A/Form-B relay pair is
required in a space-saving single package.
