DTA72 is a motor thermistor monitoring relay.

Through the motor internal PTC or PTCs the DTA detects when one or more motor windings are exceeding the maximum operating winding temperature.

The PTC type installed in the motor is different according to the motor insulation temperature.

The temperature triggering threshold is detemined by the PTC Type.

DTA72 is equipped with 2 outputs which operate in a complementary mode.

It can be set to operate as MANUAL or AUTO reset.

Benefits

• High operating safety. The thresholds are determined by the Motor internal PTC. Beyond the specified temperature the output stops the motor/s.

• Save time and costs.There is no need to connect other additional and expensive controllers.

• Ensure continuous production process in your plant. This type of controller allows limitation of false alarms which may be the cause of useless interruptions of production systems when comparing with other electrical measures (i.e. current or power).

• Two outputs. The 2 ouputs provide, besides interrupting the motor supply, an additional signal for a lamp, PC or PLC.

• Bi-colour front LED. It provides indications about alarm status and alarm discrimination.
