DESCRIPTION
The 66327 high voltage isolator consists of an 850 nm LED optically coupled to a photodiode driven detector. The isolator
provides high isolation and fast switching speeds over the specified temperature range of -40ºC to +100ºC.The isolator is built
with hermetic components internally optically coupled and encased in a high temperature outer PPS plastic housing.
