Product Description
DIA01 and PIA01 are precise
AC/DC over current monitor-
ing relays. Direct measuring
or through current transformer.
Owing to the built-in latch
function, the ON-position of
the relay output can be
maintained.
The red LED indicates the
relay status. Through the
built-in shunt it is possible to
monitor loads up to 5 A
AC/DC.
