• VIN / GND: DC 5.0V-30V power input. Micro USB 5.0V can also be used for power.
• DC+ / DC-: Киргизүү тtage terminals (5.0V-30V).
• КҮЙҮК: Normally Open terminal of the relay.
• COM: Common terminal of the relay.
• ТӨМӨН: Low-level trigger input (NPN normally open sensor can be connected).
• ЖОГОРКУ: High-level trigger input (PNP normally open sensor can be connected).
• GND (Trigger): Ground for trigger inputs.
• TTL Serial Communication (GND TX RX): For advanced control and data communication.

3. Орнотуу жана зымдар

3.1. Электр кубатын кошуу

The module can be powered by a DC 5V-30V source connected to the VIN/GND terminals or via a 5.0V Micro USB cable. Ensure the correct polarity when connecting the DC power supply to prevent damage.

3.2. Load Wiring

The relay output is a passive contact (ON, COM). This means it acts as a switch and does not provide power to the load. You must connect your load and its power source through these contacts.

1. Identify the power source for your load (e.g., DC 12V, AC 220V).
2. Connect one side of your load to the power source.
3. Connect the other side of your load to the ON (Normally Open) terminal of the relay.
4. туташтыруу COM (Common) terminal of the relay to the other side of your load's power source (e.g., ground for DC, neutral for AC).
5. Бардык байланыштар коопсуз жана изоляцияланганын текшериңиз.

Warning: Always disconnect power before making any wiring changes. Incorrect wiring can damage the module or connected devices.

3.3. Trigger Input (Optional)

If using an external trigger, connect it to the LOW or HIGH trigger input terminals and the corresponding GND. The type of sensor (NPN for LOW, PNP for HIGH) determines the appropriate connection.

4. Иштөө нускамалары

4.1. Дисплей режимдери

The module has several display modes, indicated by the LED display. The default display shows the current operating mode or time value.

4.2. Parameter Settings (OP, CL, LOP)

The module supports various operating modes, each with specific parameters:

• OP: On-time (relay closes for this duration).
• CL: Off-time (relay opens for this duration).
• LOP: Loop count (number of cycles for cycle mode).

These parameters are independent and automatically saved.

4.3. Программалоо режимине кирүү

1. басып, кармап туруңуз Ачкычты коюу (gear icon) for 3 seconds to enter programming mode. The display will show the current operating mode (e.g., P1.1).
2. колдонуу Көбөйтүү жана Кыскартуу buttons to select the desired operating mode (P1.1 to P5.x).
3. басыңыз Ачкычты коюу briefly to enter parameter setting for the selected mode. The first parameter (e.g., OP) will flash.
4. колдонуу Көбөйтүү жана Кыскартуу маанисин тууралоо үчүн баскычтар.
5. басыңыз Ачкычты коюу briefly to move to the next parameter (e.g., CL, LOP). Repeat adjustment.
6. After setting all parameters for the mode, press and hold the Ачкычты коюу for 3 seconds to save settings and exit programming mode. The module will return to its normal operating state.

4.4. Time Unit Selection

While in parameter setting mode (e.g., OP flashing), briefly press the Шашылыш токтотуу ачкычы (power icon) to cycle through time units:

• xxx. (decimal point in the hundreds place): 0.1 seconds to 99.9 seconds
• xx.x (decimal point in the tens place): 1 second to 999 seconds
• x.x.x. (no decimal points): 1 minute to 999 minutes

4.5. Шашылыш токтотуу функциясы

баскычын кыскача басыңыз Шашылыш токтотуу ачкычы (power icon) during operation to immediately stop or start the relay output. The display will show "OFF" when stopped and "ON" when active.

4.6. Уйку режими

If no operation is performed for 3 minutes after startup, the display will automatically turn off to save power. Press any button to wake up the display and resume operation.
