Features:
1. The time is controlled by an industrial-grade single-chip microcomputer, with high precision and stable performance;
2. Two adjustable resistors are used to adjust the time, which can independently adjust the on-time and off-time;
3. The external trigger starts, use the self-reset button to short-circuit it to start the timing. You can also short-circuit the triggers together to realize the countdown when the power is turned on, and it will be disconnected immediately when it is triggered again during operation.
4. The time range is divided into 0-100 seconds, 0-15 minutes, 0-30 minutes, 0-60 minutes, 0-120 minutes, 0-24 hours and other specifications
5. The voltage range has three specifications: 5V12V24V
Product parameters:
Optional voltage: 5V 12V 24V
Adjustable to: 0 -100s/0-15/30/60/120 mins/0-24 Hours adjustable
Package list:
Relay module*1
Single mode:
1. No action after power-on, the relay is connected after triggering, and disconnected after the time is reached
2. During the delay process after the relay is turned on, if it is triggered again, the delay will be interrupted immediately
Cycle mode:
1. No action after energized, the relay is turned on after triggering, and turns off after T1 time. It will be connected after T2 time is reached. So cycle. T1 and T2 are set by two adjustable resistors
2. During the delay working process, if it is triggered again, the delay will be interrupted immediately
Application reference:
1. Time-limited working equipment, for example, automatically power off after 5 minutes each time the key is triggered
2. The machine repeatedly tests the circuit, for example, power on for 1 minute and then power off for 1 minute so that the cycle test
3. The fish tank pump intermittently pumps water and oxygen
4. Other time control devices
Performance:
When jumper OP1: 1 second to 100 seconds, the adjustment accuracy is 0.1 second
When jumper OP2: 1 second to 15 minutes, accuracy 1 second
The delay error is not more than 2 under various temperature and humidity
