£99.28
The Carlo Gavazzi DTA72DM24 is a compact and reliable motor thermistor monitoring relay designed to protect electric motors by monitoring PTC thermistor sensors embedded in motor windings. As part of the Carlo Gavazzi DTA72 monitoring relay series, it provides dependable overtemperature protection for industrial motors, machinery and automation systems.
This thermistor relay continuously monitors the resistance of connected PTC sensors and switches its relay outputs when excessive motor temperature is detected. With local and remote test and reset functions, it provides flexible operation for industrial control applications requiring reliable thermal protection.
With support for up to 6 PTC thermistors connected in series, a 24–240 V AC/DC supply voltage and 2 SPDT relay outputs, the DTA72DM24 is suitable for protecting motors and electrical equipment in demanding industrial environments.
Motor thermistor relays such as the Carlo Gavazzi DTA72DM24 provide continuous monitoring of motor winding temperature to help prevent overheating and equipment damage. By responding to increased PTC resistance values, the relay can disconnect or signal faults before serious thermal stress occurs.
The DTA72 series is designed for industrial automation engineers and panel builders requiring dependable motor protection in compact control systems. Its flexible supply range, relay outputs and reset functions allow easy integration into a wide range of electrical installations.
