Carlo Gavazzi Monitoring Relay Temperature Thermistor Din-Rail DTA72DM24

Carlo Gavazzi Monitoring Relay Motor Thermistor PTC Input w/Test & Reset Button, Over Temperature 3.6kOhm, Reset 1.58kOhm, DIN Rail, SPDT, Supply: 18-265VAC/DC.

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 determined 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.

Applications

This product is extremely suitable for pumps temperature monitoring. It can be useful in all applications where motors are used especially where overloads are frequent and may cause motor damages: pumping stations, water treatment, conveyors, material handling, HVAC, chillers. etc.

General Characteristics

• 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 outputs 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.
