Feature:
1. With start stop function, the module enters infinite cycle mode after starting, and the relay works on and off according to the set time.
2. Infinite cycle power on and power off modules, the delay time can be adjusted separately, the longest delay can be 1000min.
3. Low power consumption of the control board, less than 1W.
4. Start external wiring button: Passive switch input. The green light turns on after starting, and stays in the red light after stopping.
5. The button is required to be unlocked (ie self resetting). It can also be connected to external voltage signals. When the voltage is lower than 2V, it is low level. When the voltage is higher than 2V, it is high level. The maximum input should not exceed 30V.
Specification:
Item Type: Cyclic On Off Relay Module
Voltage: DC 12V
Power Consumption: <1.0W
Output: Passive output (ie dry contact), a group of normally open + normally closed. Do not exceed 10A.
Life: 100,000 operations
Time Range: 0.5 seconds 1000 minutes
Time Accuracy: the maximum value of the range * 0.001, that is, 1000 level resolution
Start external wiring button: Passive switch input. The green light turns on after starting, and stays in the red light after stopping.

Wiring Terminal:
< DC + Module power supply positive input
< DC Module power supply negative input
> NO Normally open contact wiring terminal
> COM Common contact wiring terminal of relay
> NO Normally closed contact terminal of the relay, generally not connected.
Instructions:
Time can be set in both power on and power off states
Please refer to the detailed explanation of the actual photos and pictures later to understand the operation method more intuitively.
1. ON time setting:
The potentiometer under the RUN TIME mark adjusts the time, clockwise to increase the duration, and counterclockwise to shorten the duration.
The left side of the down dial switch of the potentiometer is the time range setting. The adjustable range of the adjustable resistor is 0 100 after dialing down; the range of 0 1000 after dialing up.
The right side of the down dial switch of the potentiometer is set in units. Dial down to Sec. For seconds; dial up to Min. For minutes.
2. OFF duration setting:
The potentiometer under the OFF TIME mark adjusts the time, clockwise to increase the duration, and counterclockwise to shorten the duration.
The left side of the down dial switch of the potentiometer is the time range setting. The adjustable range of the adjustable resistor is 0 100 after dialing down; the range of 0 1000 after dialing up.
The right side of the down dial switch of the potentiometer is set in units. Dial down to Sec. For seconds; dial up to Min. For minutes.
3. Start button:
Connect the self reset button, press it once, switch to green light, indicating running status, the module will automatically work according to the set running time and stop time, infinite cycle. At this time, press the start button again, the module will switch to a red light, indicating that it is in a stopped state.
4. Example of time setting:
Requirements: 20 seconds on, 30 minutes off, infinite loop.
Settings:
(1) Dial down the running time range to 0 100;
(2) Dial down the running time unit to seconds;
(3) Rotate the running time potentiometer to 20 position, that is, 20 100 position from the left;
(4) Dial down the stop time range to 0 100;
(5) Dial up the stop time unit to minute;
(6) Rotate the stop time potentiometer to 30 position, that is, 30 100 position from the left;
Note: The position of the potentiometer can also be quickly located by measuring the voltage. The minimum adjustment of the central arm is 0V, and the highest position is 5V. For example, it needs to be adjusted to 20, that is, 20 100 * 5V = 1.0V; to be adjusted to 30, it is 30 100 * 5V = 1.5V
Option description:
Operating mode:
(1) RD72 DC A Standard: Press the start button once to start the cycle, and then press the start button again to stop the work. The starting cycle mode is: on off on off
(2) RD72 DC AS Enable version: Press and hold the button to start the infinite loop, release the button to stop the loop and jump to the disconnected state. The starting cycle mode is: on off on off .
