Product Description Ordering Key
EIC is a precise AC/DC under
current (shunt) metering re-
lay. Measures the voltage of
an externally connected stan-
dard shunt also for high cur-
rent applications. The built-in
LED's indicate the exact sta-
tus of the output relay.

Mode of Operation
EIC measures both AC and
DC current (voltage) through
an external standard shunt.
Example 1
The relay operates when the
measured value exceeds the
set level plus the hysteresis.
When the voltage (current)
drops below the set level for
more than the set delay, or
when power supply is inter-
rupted, the relay r eleases.
The yellow LED is flashing un-
til the delay has expired, or
until the measured value ex-
ceeds the set level plus the
hysteresis.
Range/Level/Time Setting
Upper knob:
Setting of current (voltage)
range on rotary switch.
Centre knob:
Level setting on relative scale.
Lower knob:
Setting of OFF delay on abso-
lute scale (0.1-10 s).
Hysteresis
Normally 5%. The hysteresis
can be extended by inserting
a resistor between terminals
Z1 & Z2.
