Carlo Gavazzi DAC01CM24 is a 22.5 mm DIN-rail star-delta timer relay with a selectable 0.1 s to 10 min timing range, universal 24–240 V AC/DC supply and an 8 A SPDT output.

The Carlo Gavazzi DAC01CM24 is a compact and dependable star-delta timer relay designed to control the starting sequence of three-phase induction motors. As part of the established Carlo Gavazzi DAC01 timer series, it provides adjustable timing and automatic transfer between the star and delta stages of a motor starter.
This timer offers selectable timing ranges from 0.1 s to 10 min, allowing the star operating period to be matched to the motor and driven load. After the selected time expires, the relay changes state to support transfer from the star contactor to the delta contactor.
With a universal 24–240 V AC/DC supply, an 8 A SPDT relay output and a slim 22.5 mm DIN-rail housing, the DAC01CM24 is suitable for motor-control centres, pumps, fans, compressors and industrial machinery requiring reduced-current starting.
Star-delta starting reduces the current drawn by a three-phase induction motor during acceleration. The motor initially starts with its windings connected in star, reducing the voltage applied to each winding, before the timer initiates transfer to the delta connection for normal operation.
The Carlo Gavazzi DAC01CM24 controls this sequence automatically according to the selected delay. Correct coordination with suitably rated contactors and electrical interlocking helps prevent the star and delta contactors from being energised simultaneously.

The DAC01CM24 controls the timed transition between the star and delta stages of a reduced-current three-phase motor starter.
The timer offers selectable ranges covering star-stage delays from 0.1 s to 10 min.
The DAC01CM24 operates from a universal 24–240 V AC/DC supply.
The timer provides an 8 A SPDT electromechanical relay output with one changeover contact.
The timer is mounted on a DIN rail inside a motor-control panel and connected to the starter control circuit using its screw terminals.
Carlo Gavazzi timer relays are used by panel builders, automation engineers and equipment manufacturers to provide dependable timing, sequencing and motor-control functions in industrial systems.
