DTA04 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. The relay is equipped with 2 outputs which operate in a complementary mode. The DTA04 can be set to operate as MANUAL or AUTO reset. When set to manual, the front LED will notify when the motor temperature is back to normal avoiding to try to restore operation uselessly. Features: High operating safety. The thresholds are determined by the Motor 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. Two outputs. The 2 ouputs provide, besides interrupting the the Motor supply, an additional signal for a lamp, PC or PLC. Bi-colour front LED. These devices indicate alarms for temperature and PTC.
