Product Review

Specification:
T1(the relay turn on delay time), T2(the relay turn off delay time)
Once mode (Jumper OP3)
1. The module Power-on, When triggered the relay is switched on, delay T1, and the relay disconneted. #REF!

Cycle mode(Jumper OP4)
1. The module Power-on, When triggered the relay is switched on, delay T1,and the relay is disconneted, 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.

Performance:
Jumper OP1: 1 to 100 seconds, 0.1 seconds of regulation accuracy
Jumper OP2: 1 seconds to 15 minutes, 1 seconds of regulation accuracy
The time delay error of all kinds of temperature and humidity is not more than 2%
