5. Configurazione e cablaggio
Correct wiring is crucial for the safe and proper operation of the timer relay. Refer to the wiring diagram below for guidance.

5.1. Istruzioni per il cablaggio
- Collegamento dell'alimentazione: Connect the positive (+) terminal of your 12V DC power source to the 'POWER SUPPLY+' terminal on the relay module. Connect the negative (-) terminal of your 12V DC power source to the 'POWER SUPPLY-' terminal.
- Ingresso segnale: The 'SIGNAL TERMINAL' is where you connect your trigger signal. This can be a positive side of the power supply, a button, a PNP sensor, or a PLC signal.
- Device (Load) Connection: Connect your device (load) to the relay output terminals. The relay acts as a switch, controlling the power flow to your device based on the programmed timing. Ensure the load's current and voltage requirements do not exceed the relay's specifications (5A, 12V).
6. Modalità operative
The DROK 12V Timer Relay offers four distinct operating modes (P-1 to P-4) to suit various timing control needs. These modes are demonstrated in the video below.
6.1. Descrizioni delle modalità
- P-1: Signal Trigger, Relay Connects, Disconnects After Time (T1)
When a signal is triggered, the relay connects immediately. After the set time T1 elapses, the relay disconnects. - P-2: Signal Trigger, Delay T1, Relay Connects, Delay T2, Relay Disconnects (Reset)
Upon receiving a signal, the module starts timing T1. After T1 is over, the relay connects. Then, it starts timing T2. When T2 is over, the relay disconnects, and the module resets, waiting for the next signal. - P-3: Delay T1, Relay Connects, Delay T2, Relay Disconnects (Repeat)
This mode operates in a continuous loop. After T1 time is over, the relay connects. After T2 time is over, the relay disconnects. This cycle repeats indefinitely until power is removed. - P-4: Signal Trigger, Relay Connects, Signal Disappears, Delay T1, Relay Disconnects
When a signal is triggered, the relay connects. If the signal disappears, the module starts timing T1. After T1 is over, the relay disconnects. If the signal is re-triggered during the T1 delay, the delay stops, and the relay remains connected. If the signal disappears again, the re-timing process begins.
7. Istruzioni di programmazione
The timer relay is programmed using the three buttons (K1, K2, K3) located on the module. The LED display will guide you through the settings.
7.1. Impostazione della modalità operativa
- Enter Mode Selection: Long press button K1 until the display shows 'P-X' (e.g., P-1, P-2).
- Seleziona modalità: Short press K1 to cycle through the available operating modes (P-1, P-2, P-3, P-4).
- Modalità di conferma: Once the desired mode is displayed, short press K2 to confirm and proceed to time setting.
7.2. Setting Time Parameters (T1, T2)
- Adjust Time Value: In the time setting interface, use K3 to increase the time value. Long press K3 for faster adjustment.
- Change Time Unit: Short press K2 to switch between time units: seconds (0.0.0), minutes (0.0), or hours (0). The decimal point position indicates the unit.
- Salva ed esci: After setting all required time parameters (T1 and T2 if applicable for the selected mode), long press K1 to save the settings and exit the programming mode. The module will then enter its operational state.
Note: The module automatically saves the last settings when power is cut off.
8. Manutenzione
The DROK 12V Timer Relay is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:
- Mantenere il modulo pulito e privo di polvere e detriti. Utilizzare un panno morbido e asciutto per la pulizia.
- Regularly inspect wiring connections to ensure they are secure and free from corrosion.
- Avoid exposing the device to direct sunlight or high humidity, which can degrade components over time.
9. Risoluzione Dei Problemi
If you encounter issues with your DROK 12V Timer Relay, refer to the following common problems and solutions:
- Device does not power on / LED display is off:
• Check the 12V DC power supply connections. Ensure positive and negative terminals are correctly wired and the power source is active.
• Verify the power supply voltage rientra nell'intervallo specificato (12 V). - Relay does not activate or de-activate as expected:
• Riview your selected operating mode (P-1 to P-4) and ensure it matches your application's requirements.
• Check the signal input to the 'SIGNAL TERMINAL'. Ensure the trigger signal is correctly applied and removed according to the chosen mode.
• Verify the time settings (T1, T2) are correctly programmed and the time unit (seconds, minutes, hours) is appropriate.
• Ensure the load connected to the relay output is within the relay's current and voltage limits (5A, 12V). - Inconsistent timing or unexpected behavior:
• Ensure stable power supply. Fluctuations can affect timing accuracy.
• Check for any external electrical interference. The module has anti-interference capabilities, but strong interference can still affect performance.
• Re-program the desired mode and time settings to ensure they were saved correctly. - Difficulty understanding programming:
• Refer to the 'Programming Instructions' section in this manual.
