What is current limit
When a load current reaches the speci-
fied output control current, a current limit
function works against the load current to
keep the current a constant value.
The current limit circuit built into the Pho-
toMOS relay thus controls the instanta-
neous load current to effectively ensure
circuit safety.
This safety feature protects circuits down-

stream of the PhotoMOS relay against
over-current.
But, if the current-limiting feature is used
longer than the specified time, the Photo-
MOS relay can be destroyed. Therefore,
set the output loss to the max. rate or less.
