Output Specifications
DTA 01 C 230
DTA01, DTA02, PTA01 and
PTA02 are precise thermistor
monitoring relays.
They can be used to monitor
the temperature of the coils of
a motor with built-in PTC’s.
The alarm status of the relay
can be reset by either an
external contact or an internal
button (DTA02, PTA02).
The test button allows the
simulation of the fault condi-
tion (DTA02, PTA02).
The red LED indicates the
alarm status.
