LU-923M time-delay relay is an intelligent time alarm instrument with excellent performance and stability.

It adopts advanced ARM processor, fast processing speed,simple interface component,high accuracy in captured time,strong reliability and stability.

It has one high accuracy timing clock and 4 groups alarm register which can be combined freely.Rich time alarm outputs and the output position can be self-defined.

It can receive external reset signal event (dry point),or start the timing just press the panel button.
