Altdaten CMT
The S1IM current monitoring relay is
used to monitor the maximum current
values on heaters, lamps etc.

Unit features
Altdaten CMT
` 12 measuring ranges can be select-
ed from 0.002 to 15 A
` Reaction time can be set to up to 10
seconds
` Operates to either normally ener-
gised or normally de-energised
mode
` Galvanic isolation between measur-
ing and supply voltage
` UP version: measuring inputs are
not polarity-sensitive
Description
The current monitoring relay is en-
closed in an S-95, slimline housing.
There are 8 versions available for AC
operation and one for DC operation.
Features
` Relay outputs: 1 auxiliary contact
(C/O)
` 3 measuring circuits for 0.1 A, 2 A
and E, each with 4 different ranges
` Response value can be set from
20 % to 100 % of the measuring
range limit value
` Hysteresis factor can be set from
0.6 to 0.9 x I
on
` Fault latching or automatic reset
` LEDs for relay's switch status and
for supply voltage
The S1IM monitors for current values
exceeding a selectable threshold limit.
On the UP version, the measuring in-
puts are not polarity-sensitive. If the
measuring current reaches the re-
sponse value I
on
, auxiliary contact 11-
14 changes over and the LED lights. If
the measured current falls below the
hysteresis value I
off
and automatic re-
set is selected, the auxiliary contact
changes over again and the LED goes
out. The unit is ready for operation
again. If faults are latched, the unit will
not be ready for operation again until
an external reset button is operated or
the supply voltage has been switched
off and then on again.
