1 channel relay module with timer and logic signal control
Logic signal voltage: 3-24V DC, suitable for Arduino, Raspberry Pi and other similar microcontrollers
Relay-controlled current: up to V36 10A DC
The LED indicates the operating status of the relay and the board
The signal and power circuits are separated, can be connected by soldering the pads
Work Mode:
P1.1:Output keep ON for time OP after get trigger signal and then OFF;The input signal is invalid if get trigger signal again during delay time OP.
P1.2:Output keep ON for time OP after get trigger signal and then OFF;Output will restart delay if get trigger signal again during delay time OP.
P1.3:Output keep ON for time OP after get trigger signal and then OFF;Output will reset and stop timing if get trigger signal again during delay time OP.
P2:Output keep OFF for time CL after get trigger signal and then output keep ON for time OP and then output will OFF.
P3.1:Output keep ON for time OP after get trigger signal and then output keep OFF for time CL and then loops the above action.Output will reset and stop timing and output OFF if get trigger signal again during loops.The number of cycles (LOP) can be set.
P3.2:Output keep ON for time OP after power on without get trigger signal and then output keep OFF for time CL and then loops the above action.The number of cycles (LOP) can be set.Note:this mode no need input signal.
P4:Signal hold function.Reset delay time and relay keep ON if keep get trigger signal.Output OFF after delay time OP when the signal disappears.Reset delay time when get trigger signal again during timing.
Timing range:
Continuously adjustable from 0.1 seconds to 999 minutes.
Enter the settings interface when short press button ‘STOP’ in the OP / CL parameter modification interface(Flashing) to select timing range.
Pay attention to the position where the decimal point moves when the button is pressed.
Display ‘XXX’ No decimal point, the timing range is 1 second ~ 999 seconds.
Display ‘XX.X’ The decimal point is the penultimate, timing range is 0.1 second to 99.9 seconds.
Display ‘X.X.X’ The decimal point is fully lit, timing range is 1 minute to 999 minutes.
For example, if you want to set the OP to 3.2 seconds, move the decimal point to the penultimate position, Screen will display ‘03.2’
OP and CL parameters are the same in different work mode.
It will display OP(CL,LOP) and corresponding delay time by short press button SET in main display interface(when display 000).
It just display OP and corresponding delay time in P1 mode by short press button SET in main display interface.
Parameter Description:
OP: Delay time for turn On;
CL: Delay time Turn OFF;
LOP: Number of cycles.Range is 1-999tims.’—-’ means unlimited loop
Set Parameter:
Long press:keep press button for more than 3second.
Enter set parameter menu by long press button ‘SET’.
Work mode will flash at first when set the working mode.Short press the UP/DOWN button to select working mode P1~P4.
Short press SET button to enter the system parameter settings interface.
In the system parameter setting interface, short press the ‘SET’ button to switch the system parameters to be modified, short/long press the UP/DOWN button to modify value;
Short press button ‘STOP’ to select timing range.
Short press button SET to set next parameter.
Save the parameter settings and exit the settings interface when long press ‘SET’ button after all the parameters are set.
Main interface:Display 000 if no output.
Set interface:Long press SET button enter into set interface.Long press SET button again into main interface after set parameter.
Additional Features:
Auto sleep function: Long press button ‘STOP’ in the normal running interface to turn on or off auto sleep function.
C-P:Turn ON auto sleep function.Screen will automatically turns off if there is no operation within five minutes.It can be wake up by any buttons.
O-d:Turn OFF auto sleep function.
Enabled/Disabled output by short press button STOP:
ON:Enabled output during delay time OP.
OFF:Disabled output during delay time OP.Module can not output any signal at this mode.
Common ground:User can connect GND of trigger signal to GND of module by short pads GND-T and GND.But it is not recommended, which will reduce the anti-interference ability of the module.
