This image shows the underside of the DEVMO JZ801 relay board, revealing the solder points, circuit traces, and the model number 'JZ-801' printed on the PCB. It also indicates the power input terminals (6.0~30.0V, GND) and trigger input (Trigger, GND_TO).

3.1 Mewnbwn Pwer

• Mewnbwn DC: Connect a DC power source between 6V and 30V to the screw terminals labeled 6.0 ~ 30.0V (cadarnhaol) a GND (negyddol).
• Mewnbwn Micro USB: Alternatively, power the module using a 5V Micro USB power supply connected to the Micro USB port.

3.2 Mewnbwn Sbardun

• The trigger source requires a high voltage level between 3.0V and 24V.
• Connect the trigger signal to the terminal labeled Sbardun and the ground reference to GND_TO.

3.3 Allbwn Ras Gyfnewid

The relay provides three terminals for connecting your load:

• NA (Ar agor fel arfer): This terminal is open (disconnected) when the relay is de-energized and closed (connected to COM) when energized.
• COM (Cyffredin): This is the common terminal for the relay switch.
• NC (Ar gau fel arfer): This terminal is closed (connected to COM) when the relay is de-energized and open (disconnected from COM) when energized.

The relay can control devices within DC 0-30V 5A or AC 0-220V 5A.

4. Cyfarwyddiadau Gweithredu

4.1 Main Interface and Display

When the module is off, the display shows "000" (no decimal point). During operation, the display will show a decimal point, indicating active status.

This image highlights the 3-digit LED display and the three control buttons (SET, STOP, and an unlabeled button) on the DEVMO JZ801 relay board, which are used for programming and operating the module.

4.2 Diffiniadau Paramedr

• OP: Turn-On Time (duration the relay is energized).
• CL: Turn-Off Time (duration the relay is de-energized).
• LOP: Cycle Index (number of cycles). "---" indicates an limitless cycle.

These parameters are independent for each work mode but share the same values across different modes once set.

4.3 Gosod Amser

To set timing values:

1. Enter the mode selection screen (see Section 4.4).
2. After setting the parameter values (OP, CL, LOP), short press the AROS button to select the time range for the currently displayed parameter.
3. Available time ranges:
• XXX: 1 second to 999 seconds (e.g., 123 for 123 seconds).
• XX.X: 0.1 seconds to 99.9 seconds (e.g., 12.3 for 12.3 seconds).
• X.X.X.: 1 minute to 999 minutes (e.g., 1.2.3. for 123 minutes).

4.4 Work Mode Selection

Pwyswch yn hir y GOSOD key to enter or exit the mode selection screen. In this screen, you can choose different operational modes for the relay.

4.5 Relay Enable/Disable Mode

From the main interface, a short press of the AROS button will toggle the relay between ON and OFF states, effectively enabling or disabling its operation.

4.6 Modd Cwsg

To activate or deactivate sleep mode:

1. Pwyswch yn hir y AROS botwm am ddwy eiliad.
2. Release the button to switch between Cl (normal mode) and O-d (sleep mode) states.

In sleep mode, if there is no operation for five minutes, the digital display automatically turns off to save power. Press any key to turn the display back on.

5. cynnal

• Keep the module clean and free from dust and moisture.
• Osgoi amlygu'r modiwl i dymereddau eithafol neu olau haul uniongyrchol.
• Ensure all connections are secure to prevent intermittent operation.
• Do not attempt to modify the circuit board, as this may void any warranty and cause damage.

6. Datrys Problemau

• Modiwl ddim yn troi ymlaen: Gwiriwch y cyflenwad pŵer cyftage is within the 6-30V range for DC input, or ensure the Micro USB cable is properly connected to a 5V source. Check for correct polarity on DC input.
• Relay not triggering: Ensure the trigger signal voltage is between 3.0V and 24V. Check the trigger input connections for proper contact. Verify the selected work mode and timing parameters are correctly configured.
• Incorrect timing: Double-check the OP, CL, and LOP parameter settings. Ensure the correct time range (seconds, 0.1 seconds, minutes) is selected for each parameter.
• Mae'r arddangosfa i ffwrdd: The module might be in sleep mode. Press any button to reactivate the display. If not in sleep mode, check power supply.
• Gweithrediad ysbeidiol: Check all wiring connections for looseness. Ensure the load current does not exceed the relay's maximum rating (DC 0-30V 5A or AC 0-220V 5A). The built-in opto-isolator helps reduce interference, but ensure your environment is free from excessive electrical noise.
