Description
The CPC1333 is a single-pole, normally closed
(1-Form-B) Solid State Relay with an enhanced input
to output isolation barrier of 5000Vrms.
The relay output is constructed with efficient
MOSFET switches that use IXYS Integrated Circuits'
patented OptoMOS architecture. The input, a highly
efficient infrared LED, controls the optically coupled
output.
