12V DC Infinite Cycle Delay Timing Timer Relay

Features:

• This module uses MCU as the main chip.
• High timer precision.
• MCU watchdog circuit and special reset chip.
• Stable and reliable work.

T1(the relay turn on delay time), T2(the relay turn off delay time)

1. 
   

Once mode (Jumper OP3)
1. The module Power-on, When triggered the relay is switched on, delay T1, and the relay disconnected.
2. When triggered on the delay process, again triggered, it will immediately interrupt the delay.

Cycle mode(Jumper OP4)

1. The module Power-on, When triggered the relay is switched on, delay T1,and the relay is disconnected, delay T2,
the relay is switched on again. Such cycle. T1 and T2 are set by two adjustable resistors, respectively.
2. When triggered on the delay process, again triggered, it will immediately interrupt the delay.

Typical application reference

1. timer operating equipment, such as each press key trigger,when reach 5 minutes the automatic power off.

2. machine repeat test circuits, such as power 1 minutes on and then power off 1 minutes of ,such a cycle

of testing.

3. fish tank pump intermittent pumping oxygen.

4. other timer control equipment.
