EID is a precise AC/DC under
current metering relay and of-
ten used in applications where
small loads have to be con-
trolled. The built-in LED's in-
dicate the exact status of the
output relay. Through the built-
in shunt it is possible to meas-
ure loads up to 10 A.

EID measures both AC and
DC under current through an
internal shunt.
Example 1
The relay operates when the
measured value exceeds the
set level plus hysteresis.
When the current dr ops below
the set level for more than
the set delay, or when power
supply is interrupted, the relay
releases.
The yellow LED is flashing until
the delay has expired, or until
the measured value exceeds
the set level plus the hystere-
sis.
