Thermisches Relais PTC-Typ MSF 220 V / VU

for Dry-Transformers, 3 PTC-Circuits
MSF 220 V/VU
The MSF 220 V is particularly suitable for the temperature monitoring at dry transformers.
3 PTC-circuits with different nominal response temperatures (NRT) can be connected to this
unit, one for controlling an fan (forced cooling) and two for alarms.
Each PTC-circuit is monitored for break and short circuit. This reduces the probability of false
alarms.
 
3 PTC-circuits
MSF 220 VU for universal
supply voltage AC/DC 24-
240 V
intelligent control of fan (relay
K0, 1 normally-open contact)
ALARM 1 in closed-circuit
current mode (relay K1, 1
change-over contact) for prealarm.
Signals also error in
any sensor and interruption
of supply voltage.
ALARM 2 in operation current
mode (relay K2, 1 changeover
contact). No signal when
switching on ond off the supply
voltage.
all output relays potentially
separated from each other.
monitoring of sensor lines
TEST-button (stop possible
before ALARM 2)
simple testing with disconnectable monitoring of
break and short-circuit (for 10 minutes)
LEDs for ON, sensor error, Fan, ALARM 1 and
ALARM 2
plug-in terminals
housing for mounting on DIN-rail
