Feature(may vary by option.)

●This module uses a single chip microcomputer as a time-accurate main control core. MCU built-in watchdog circuit and dedicated reset chip ensure stable and reliable operation. Adopts industrial grade single chip microcomputer to control time with high precision and stable performance
●You can adjust the time using two adjustable resistors to independently adjust the on-time and off time
●External contact activates and timing starts by short circuiting with self-reset button. You can also shorten the trigger together and start countdown when the power is on. When it is triggered again during operation, it will disconnect immediately
●Suitable for aquarium pump intermittent oxygen pumping and other time control equipment
●The time range is divided into specifications that can meet your various needs such as 0-100 seconds, 0-15 minutes, 0-30 minutes, 0-60 minutes, 0-120 minutes, 0-24 hours, etc


Description

Specifications:
Voltage: 5V/12V/24V
Dimension: 61.5*23.2mm
Single Mode:
1. It will not work after power on, the relay will turn on after trigger and disconnect after arrival time.
2. During the delay after the relay is turned on, if you trigger it again, the delay will be immediately interrupted.
Loop Mode:
It will not work when you turn it on. After triggering, the relay is turned on, and it will be disconnected when it reaches T1 hour. Turn on when T2 hours reached. In this cycle, the T1 and T2 are set by two adjustable resistors.
When it is triggered again by a delayed work process, the delay will be immediately interrupted.
General Application Reference:
1.Time-limited work equipment. For example, if the button activates for 5 minutes, it will automatically turn off.
2. The machine repeats the test circuit. For example, it is a test to run power for 1 minute, then turn off the power for 1 minute.
3. The water pump in the aquarium will intermittently pump up water to release oxygen.
4.Other time control devices
PERFORMANCE:
Jumper OP1: 1 second to 100 seconds, adjustment accuracy 0.1 second
Jumper OP2: 1 second to 15 minutes, accuracy of 1 second.
Delay error of less than 2% under varying temperature and humidity
Basic Work Principle:
1. Using the factory standard settings for example, the power is on, and the red LED will light up when the relay is turned off. When the trigger terminal is short, the green LED on the module will light up and enter into working condition. When triggered again in working state, it will stop working.
2, In working state, the relay passes T1 seconds, interrupts T2 seconds, passes T1 seconds, and interrupts T2 seconds....infinity loops. T1, T2 is the length of the time the user adjusts through an adjustable resistor.
Note:
1. Due to the light and screen difference, the items color may be slightly different from the pictures.
2. Please allow 1-3cm differences due to manual measurement.
