This all solid-state relay utilizes the latest
ELECTRICAL SPECIFICATIONS
technology to provide a low ON resistance and
an optically isolated output. The control (input)
(-55C TO +105C UNLESS OTHERWISE NOTED)
and load (output) are optically isolated to protect

The optical isolation also provides a full floating

output, thus allowing the load to be connected to
either output terminal. The control circuit is
