## **Dimensions** (mm) 

Net weight : Approx. 100g 

- When power is applied, the NO timed contacts make after the set time has elapsed. 

- When power is removed the timer resets. 

- Timed contact When power is applied, the NO contact makes after the set time has elapsed. When power is removed, the timer resets. 

• Instantaneous contact When power is applied, the NO contact makes instantly. When power is removed, the timer resets. 

- When power (2-7) is ON, the NO timed contacts (1-3, 8-6) are instantly closed. When power is OFF, they are opened after the set time has elapsed. 

- When power (2-7) is ON, the NO (1-3, 8-6) and the NC (1-4, 8- 5) timed contacts are alternately closed to repeat the ON-OFF operations. 

- When power is OFF the timer resets.
