The relay opens again. Such a cycle. T1 and T2 are respectively set by two adjustable resistors. MCU watchdog circuit and special reset chip. The relay is triggered, when T1 is delayed and the relay is off, the module will open.

12v DC delay turn on or delay turn off the module. Quiescent current: 13mA (relay for unlock). Maximum power consumption: 48mA (relay latch). Anti-power-down for protection diode, better for protection module.

If there is always trigger signal, relay will keep energized until trigger signal disappears, then dis-energized after 0 to 25 seconds. 12V trigger delay normally open relay module, repeatedly triggering effective.

Quiescent current: 13mA (relay for unlock). 12v DC delay turn on or delay turn off the module. Maximum power consumption: 48mA (relay latch). Large current load can be connected (250V AC 10A or 30V DC 10A).

The relay opens again. Such a cycle. T1 and T2 are respectively set by two adjustable resistors. The relay is triggered, when T1 is delayed and the relay is off, the module will open. Repeat the test circuit, for example B. 1 minute, and then close the test loop for 1 minute.
