When the output current exceeds a fixed
amount, it is cut and the off state is main-
tained. The relay can be restored by turn-
ing off the input current and then turning it
back on.

What is short circuit protection?
When the load current exceeds specifica-
tions, the short circuit protection function
kicks in and completely cuts off the load
current, thus turning off the relay.
The short circuit protection inside the
PhotoMOS relay instantaneously
(typ. 50 µs) and completely cuts of the
load current.
This protects any circuits that follow the
PhotoMOS relay from excess current.
There is almost no heating of the Photo-
MOS relay, which prevents it from becom-
ing damaged. To restore the function of
the relay turn off the input current and
then turn it back on.

Detection time
(approx. 50
µs)
The short circuit current
detection device latches
when the relay is off.
The relay operates normally
when the input current is reset.
If the output section shorts even after
the input current is reset, it will latch
when the short circuit current is
detected again and the relay turns off.
