What is short circuit protection latch type?
When the load current exceeds
specifications, 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
PhotoMOS relay, which prevents it from
becoming damaged. To restore the
function of the relay turn off the input
current and then turn it back on.
In order to operate the short circuit
protection function, ensure that the input
current is at least I
F
= 5 mA.

Abnormal current
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.
