Trigger signal source: high-level trigger DC 3.0V—24V signal ground and system ground to improve the system's anti-interference ability can also short-circuit the ground
Output capacity: controllable DC 30V/10A or AC 250V/10A equipment
Product size: 64mm*35mm*19.3mm
Mounting hole: diameter 3mm
Working temperature: -40 ° C ~ 85 ° C
Operating mode:
P1 mode: After the signal is triggered, the relay turns on the OP time, then turns off; in the OP time, the following operation
P1.1: The signal is triggered again.
P1.2: Signal triggers re-timed again
P1.3: The signal triggers reset again, the relay is disconnected, and the timing is stopped.
P-2: Give the trigger signal, after the relay turns off the CL time, the relay turns on the OP time. After the timing is completed, the relay is turned off.
P3.1: Give the trigger signal, after the relay turns on the OP time, the relay turns off the CL time, then loops the above action, the signal is given again in the cycle, the relay is disconnected, the timing is stopped; the number of cycles (LOP) can be set
P3.2: No trigger signal is required after power-on, the relay turns on OP time, the relay turns off CL time, and the above actions are cycled; the number of cycles (LOP) can be set
P-4: Signal hold function If there is a trigger signal, the timing is cleared, and the relay remains on; when the signal disappears, the relay is turned off after timing the OP; during the timing, there is a signal, and the timing is cleared.
Relay enable mode:
ON: The relay is allowed to conduct during the OP conduction time.
OFF: The relay is prohibited from being turned on and is always off.
Short press the STOP button on the main interface to switch between ON and OFF. The current state will flash, then return to the main interface. This function is the emergency stop function, with one button to open and close the relay.
Sleep mode (long press the stop button to view the current mode):
C-P sleep mode: within five minutes, without any operation, the digital tube automatically turns off the display, and the program runs normally.
O-d normal mode: the digital tube is always on display
Press and hold the STOP button for 2 seconds and then release it to switch the C-P and O-d states. The current state will flash and then return to the main interface.
Timing range
How to choose the timing range
After setting the parameter value in the mode selection interface, press the STOP button to select the timing range.
XXX. Decimal point is in one place, timing range: 1 second to 999 seconds
XX.X decimal point in ten, timing range: 0.1 seconds to 99.9 seconds
X.X.X. The decimal point is fully illuminated, and the timing range is from 1 minute to 999 minutes.
For example, if you want to set the OP to 3.2 seconds, move the decimal point to ten digits, and the digital tube displays 03.2.
Parameter description: OP on time, CL off time, LOP cycle number 1-999 times, "---" stands for infinite loop
These parameters are independent of each other, but each mode shares these parameters. For example, when the on-time OP is set to 5 seconds in P1.1, the user wants to switch to the P1.2 mode, then when entering the P1.2 setting corresponding parameters, the OP also Will be 5 seconds
Displaying 000 on the main interface and pressing the SET button will display OPL, LOP, and corresponding time XXX
If only OP in the mode, such as mode P1.1, P1.2, P1.3 time, then short press SET button will only display OP and the corresponding time
If the mode has OP, CL, and LOP such as mode P3.1, P3.2 short press SET button will display OP and corresponding time, CL and corresponding time, LOP and corresponding times
After setting the mode, it is very convenient to view the parameters set in the current mode by pressing the SET button on the main interface.

How to set parameters
1) First determine the working mode of the relay
According to the working mode of the relay, in the main interface (when the module is powered on, it will flash the current working mode (default P1.1 mode), then enter the main interface "press and hold the SET button for 2 seconds and then release" to enter the mode selection. Interface, select the mode to be set by short-pressing the UP and DOWN buttons.



2) After selecting the mode to be set (for example, P3.2), press the SET button to set the corresponding parameter. At this time, the parameter to be selected will flash OP ON time, CL OFF time, LOP cycle number “---” Represents an infinite loop, adjusts the parameter value through UP and DOWN, supports long press (rapid increase or decrease), and short press (increase or decrease 1 unit); after setting the parameter value, select the decimal point position by short pressing the STOP button. , select the timing range (corresponding time 0.1 seconds ~ 999 minutes); short press the SET button to set the following parameter of the current mode, the process is the same as above
3) After setting the parameters of the selected mode, press and hold the SET button for 2 seconds to release, the currently set mode will flash, then return to the main interface and set the parameters successfully.
4) Main interface: “000” (no decimal point) is displayed when the relay is not working, and the decimal point is clear when the relay is working.
5) Mode selection interface: long press the SET button to enter, after the setting is completed, long press SET button to exit, and return to the main interface.
