DC12V Adjustable Infinite Cycle Loop Delay Timer Time Relay Switch ON OFF Module

Made of high-quality materials,

This module uses MCU as the main chip

High time accuracy

MCU watchdog circuit and special reset chip

Fine workmanship, good performance

StaLong's life

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

Color: as shown

Voltage: DC12V

-time mode( for Jumper OP3)

1. The relay is triggered, when T1 is delayed and the relay is off, the module will open.

2. If it is triggered during the re-trigger delay, the delay will be interrupted immediately.

Cycle mode( for Jumper OP4)

1. After the module is powered on and triggered, the relay is turned on, the delay time is T1, and the relay is turned off, and the delay time is T2. The relay opens again. Such a cycle. T1 and T2 are respectively set by two adjustable resistors.

2. If it is triggered during the re-trigger delay, the delay will be interrupted immediately.

Typical application reference:

1. The timer device is like everyone, press the exit button when it automatically shuts down after 5 minutes.

2. Repeat the test circuit, for example B. 1 minute, and then close the test loop for 1 minute.

3. The middle of the fish tank pump supplies oxygen to the water pump.

4. Other timing equipment.

which performed:

1s-15min version: for Jumper OP1: 1 to 100 seconds, control accuracy is 0.1 second. for Jumper OP2: 1 second to 15 minutes, control accuracy is 1 second.

The time delay error of all types of temperature and humidity does not exceed 2%.
