Carlo Gavazzi Monitoring Relay Temperature Thermistor Din-Rail DTA71CM24

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

DTA71 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. The relay is equipped with 1 SPDT relay output and 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).
• Bi-colour front LED. It provides indications about alarm status and alarm discrimination.
