PTC-resistor relays type MS
The MSF220SE is a 2-channel
PTC resistorrelay. It is used
favourably wherever an alarm
has to be supressed for a short
period when applying the supply
voltage.
2 PTC resistor sets
2 output-relays with change-
over contacts (co)
integrated timing-relay K3 to
suppress an alarm-impulse
when switching on supply
voltage
ALARM 1, i.e. for preliminary
alarm
ALARM 2, i.e. for switching o
power on green LED
ALARM 1 yellow LED
ALARM 2 red LED
Test-button for testing of re-
lays K1/K2
time-delayed signal (2-4s) of
K3 available at terminal 1 for
extarnal use
Thanks to the delayed switching-
on of relay K3, the MSF 220 SE
is especially suitable in applicati-
ons, where an auxiliary voltage is
not available and the secondary
voltage of the monitored transfor-

mer is being used as supply voltage.
As a consequence of this feature, there will be no
alarm case of failure of supply voltage. We recom-
mend therefore the monitoring of the function of K3 at
terminals 1 or 7.
