Pilz S1IM Data Sheet

Electronic Monitoring Relays

Single-phase current monitoring

S1IM

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

Features

● 12 measurement ranges can be
selected from 0.002 to 15 A

● Reaction time can be set for up
to 10 seconds

● Operates to normally energised
or normally de-energised mode

● Galvaninc isolation between
measuring voltage and supply
voltage

● UP version: Measuring inputs
are not polarity-sensitive

Electronic Monitoring Relays

Single-phase current monitoring

S1IM

The S1IM monitors whether a set
current value has been exceeded.
On the UP version the measuring
inputs are not polarity-sensitive.
If the measured current reaches the
response value Ion, the auxiliary
contact 11-14 switches and the LED
is illuminated. If the measured
current falls below the hysteresis
value I
selected, the auxiliary contact
switches again and the LED goes
out. The unit is once again ready for
operation. If faults are latched, the
unit is not ready for operation again
until an external reset button is
activated or the supply voltage has
been switched off and on again.
