£90.28
The Carlo Gavazzi DTA71CM24 is a reliable motor thermistor monitoring relay designed to protect electric motors by monitoring temperature through integrated PTC thermistors. Part of the Carlo Gavazzi DTA71 monitoring relay series, it provides dependable thermal protection for industrial motors, pumps and automation systems.
This relay monitors up to 6 PTC thermistors connected in series and detects excessive motor winding temperatures to initiate protective switching. Its compact 35 mm DIN-rail housing enables straightforward installation inside industrial control panels.
With a universal 24–240 V AC/DC supply voltage, automatic reset function and a single SPDT relay output, the Carlo Gavazzi DTA71CM24 provides efficient motor temperature supervision for demanding industrial applications.
Thermistor monitoring relays provide an effective method of protecting motors against overheating by monitoring PTC sensors embedded within motor windings. When the temperature threshold is exceeded, the relay output changes state to help prevent motor damage.
The Carlo Gavazzi DTA71CM24 is designed for automation engineers and machine builders requiring dependable motor protection, compact DIN-rail installation and reliable temperature monitoring in industrial environments.
