Reliable Motor Starting Control for Industrial Applications
Star-delta timer relays such as the IMO TDSD1 control the sequence of a motor starter by initially connecting the motor windings in star configuration and then transferring operation to delta after the programmed time delay. This reduces the initial starting current of larger three-phase motors.
The TDSD1 is designed for control engineers, panel builders and machine manufacturers requiring a compact and reliable solution for automated motor starting systems. Its dedicated star-delta function simplifies integration into industrial control circuits.
Typical Applications
- Three-phase motor star-delta starters.
- Industrial machinery and production equipment.
- Pumps and compressor systems.
- Fans and ventilation equipment.
- Motor control panels.
- OEM automation systems.
