IMO TDSD1 star delta timer relay with 150–500 V AC supply, two changeover contacts and adjustable timing control for industrial motor starting applications.
£48.69
The IMO TDSD1 is a compact and reliable star delta starter timer relay designed for automatic motor starting control in industrial automation and electrical control systems. As part of the IMO TD timer relay series, it provides accurate timing control for star-delta motor starting sequences to reduce starting current and improve motor protection.
This DIN rail mounted timer provides dedicated star-delta switching control with two independent changeover relay contacts. Its compact modular design allows easy installation inside electrical control panels while providing dependable operation for three-phase motor applications.
With a 150–500 V AC supply range, 10 A relay switching capability, two changeover contacts and adjustable timing ranges for star operation and transition delay, the IMO TDSD1 is suitable for industrial motor starters, machinery and automation systems.
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.
