PTA01 Motor Temperature Monitoring Relay
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 condition (DTA02, PTA02).
The red LED indicates the alarm status.
