0.1 second (small) ~ 999 minutes (large) continuously adjustable
This product is simple and easy to use, and has powerful functions, but please read the operating instructions of this product in detail. It is a very practical product.
Module highlights:
1. Wide voltage power supply ( 6~30V ) supports micro USB 5.0V power supply , which is very convenient to use;
2. The interface is clear and simple, the functions are powerful, and it is easy to understand, meeting almost all your needs;
3. It has a one-button emergency stop function ( STOP button) with reverse connection protection, and will not burn if the connection is reversed;
4. Added sleep mode. After enabling, the display will automatically turn off if there is no operation within 5 minutes; it can be woken up by pressing any button;
5. You can set different OP , CL and LOP parameters, which are independent of each other and saved separately;
6. All setting parameters are automatically saved when power is off.
Operating mode :
● P1 : After the signal is triggered, the relay is turned on for OP time and then turned off; during the OP time, the following operations are performed,
● P1.1 : The signal is invalid when triggered again,
● P1.2 : The signal triggers the re-timing,
● P1.3 : The signal triggers reset again , the relay is disconnected, and the timing stops;
● P-2 : Give a trigger signal, after the relay is disconnected for CL time, the relay is turned on for OP time, and after the timing is completed, the relay is disconnected;
● P3.1 : Give a trigger signal, the relay will be on for OP time, then off for CL time, and then repeat the above actions. Give a signal again in the cycle, the relay will be off, and the timing will stop. The number of cycles ( LOP ) can be set.
● P3.2 : After power-on, no trigger signal is needed. The relay is turned on for OP time and turned off for CL time, and the above actions are repeated. The number of cycles ( LOP ) can be set.
● P-4 : Signal holding function: If there is a trigger signal, the timing is reset and the relay remains on; when the signal disappears, the relay is disconnected after the timing is OP ; during the timing period, if there is a signal again, the timing is reset;
Product parameters:
1 : Working voltage: 6--30V , support micro USB 5.0V power supply
2 : Trigger signal source: high level trigger ( 3.0V - 24V ) The signal ground and the system ground are not common to improve the system's anti-interference ability (you can also short-circuit the common ground by yourself)
3 : Output capacity: can control devices within DC 30v 5A or AC 220v 5A
4 : Quiescent current: 20mA Working current: 50mA
5 : Service life: more than 100,000 times; Working temperature: -40 — 85 ℃; Size: 6.2*3.8*1.7cm
6 : With optical coupler isolation, enhanced anti-interference ability, industrial-grade circuit board, set parameters will be permanently restored after power failure
memory.
Special attention: The relay output is a passive contact, with no power output, and is used to control the on and off of a circuit.
Timing range
0.1 second (minimum) ~999 minutes (maximum) continuously adjustable
How to choose the timing range:
After setting the parameter value on the mode selection interface, short press the STOP button to select the timing range;
XXX. Decimal point in the units place, timing range: 1 second ~ 999 seconds
XX.X decimal point is in the tens place, timing range: 0.1 seconds ~ 99.9 seconds
XXX decimal points are all lit, timing range: 1 minute to 999 minutes
For example, if you want to set the OP to 3.2 seconds, move the decimal point to the tens place, and the digital tube will display 03.2.
Parameter description: OP on time, CL off time, LOP cycle times ( 1 — 999 times, " --- " represents unlimited cycles)
These parameters are independent of each other, but they are shared by all modes . For example, if the on-time OP is set to 5 seconds in P1.1 and the user wants to switch to P1.2 mode, then when entering P1.2 to set the corresponding parameters, OP will also be 5 seconds.
On the main interface (displaying 000 ), short press the SET button, and OP ( CL , LOP ) and the corresponding time XXX will be displayed ;
If there is only OP time in the mode (such as mode P1.1 , P1.2 , P1.3 ), short press the SET button to display only OP and the corresponding time ;
If there are OP , CL , LOP in the mode (e.g. mode P3.1 , P3.2 ), short press the SET button to display OP and corresponding time, CL and corresponding time, LOP and corresponding times;
After setting the mode, you can easily view the parameters set in the current mode by short pressing the SET button on the main interface, which is very convenient!
How to set parameters
1. First determine the working mode of the relay;
2. According to the working mode of the relay, in the main interface (when the module is powered on, the current working mode (default P1.1 mode) will flash, and then enter the main interface, " press and hold the SET button for 2 seconds and release it " to enter the mode selection interface , and select the mode to be set ( P1.1~P-4 ) by short pressing the UP and DOWN buttons ;
3. After selecting the mode to be set (e.g. P3.2 ), short press the SET key to set the corresponding parameters. The parameters to be set will flash ( OP on time, CL off time, LOP cycle times ( " --- " represents infinite cycles)). Use UP and DOWN to adjust the parameter value. Long press (rapid increase or decrease) and short press (increase or decrease by 1 unit) are supported. After setting the parameter value, short press the STOP key to select the decimal point position and the timing range ( the corresponding time is 0.1 seconds to 999 minutes ). Short press the SET key to set the next parameter of the current mode. The process is the same as above.
4. After setting the parameters of the selected mode, press and hold the SET button for 2 seconds and then release it. The currently set mode will flash and then return to the main interface. The parameters are set successfully. It's very simple!
Main interface: When the relay is not working, it displays " 000 " (without decimal point), and when the relay is working, it has a decimal point, which is very clear!
Mode selection interface : long press the SET button to enter. After setting, long press the SET button to exit and return to the main interface. It's very simple!
STOP button function extension:
Relay enable mode :
1. ON : The relay is allowed to conduct during the OP conduction time;
2. OFF : The relay is prohibited from conducting and is always in the off state;
Short press the STOP button on the main interface to switch between ON and OFF . The current state will flash and then return to the main interface. (This function is an emergency stop function, which disconnects the closed relay with one button)
Sleep Mode :
1. CL sleep mode: within five minutes, if there is no operation, the digital tube will automatically turn off the display and the program will run normally;
2. Od normal mode: the digital tube is always on;
Press and hold the STOP button for 2 seconds and then release it to switch between CL and Od states. The current state will flash and then return to the main interface.
