YOSHINE Star-Delta Delayed Start Time Relay
The YX5521 Star-Delta Delayed Start Time Relay is designed with DPDT (Double Pole Double Throw) output and an off delay function, offering an adjustable timing range from 1 second to 60 minutes. It is developed for motor star-delta starting control systems where controlled switching sequences are required. By providing a delayed release after power interruption, it helps coordinate contactor transitions within the motor starting circuit.
This model supports flexible time adjustment through a clearly marked dial, allowing users to adapt the delay setting to various operational requirements. The wide timing range makes it suitable for different load characteristics and control scenarios, from short transition intervals to longer controlled delays.
Its compact structure allows convenient installation in control panels, motor control centers, and automation cabinets. Clear terminal markings simplify wiring, while the stable switching performance supports consistent operation in industrial environments.
The YX5521 can be integrated into pump systems, ventilation equipment, and general motor-driven applications where off delay timing is necessary for orderly shutdown or transition. As part of a star-delta control arrangement, it contributes to structured timing coordination within the electrical control circuit.
