The Walfront DC 5V 12V 24V Adjustable Cycle Trigger Delay Timing Timer Relay On/Off Switch is a versatile module designed for precise timing control in various applications. It features adjustable "on" and "off" times and supports both mon (single) and cycle modes. This module is ideal for timer-operated equipment, repetitive test circuits, and intermittent pump control in systems like fish tanks.

Setup and Wiring

Proper wiring is crucial for the safe and correct operation of the timer relay module. Always ensure the power supply matches the module's voltage rating (5V, 12V, or 24V DC) and observe polarity.

Esquema de cablejat acabatview

The module supports different wiring configurations depending on whether the load shares the same power supply as the module or uses a separate power supply.

Figure 3: Detailed Wiring Diagram for the Walfront Timer Relay Module. This diagram illustrates connections for the module's power supply, a start-up button, and a load, emphasizing not to reverse power supply polarity.

Punts de connexió

• Entrada d'alimentació: Connect your DC power supply to the '+' and '-' terminals. Ensure correct polarity.
• Key Input: The 'Key' terminals are for an external trigger switch (e.g., a push button). Shorting these two wires will trigger the module. If you need the module to work recurrently after power on, connect these two wires directly.
• Sortida de relé: The relay has three terminals:
  • NC (normalment tancat): Connected to COM when the relay is off.
  • COM (Comú): El terminal comú per al commutador de relé.
  • NO (normalment obert): Connected to COM when the relay is on.
  Connect your load (e.g., motor, light) to COM and either NO or NC depending on your desired operation (normally off or normally on).

Wiring Reference 1: Shared Power Supply

In this configuration, the module and the load share the same power source. This is suitable for DC loads that operate at the module's input voltage.

Figure 4: Wiring Reference 1. This diagram shows the module and load connected to a single power supply (BT1), with the load connected between the COM and NO terminals of the relay, and a trigger switch (S1 Key) connected to the module's key input.

Wiring Reference 2: Separate Power Supply for Load

This configuration allows the module to control a load that uses a different voltage (AC or DC) than the module's power supply. The relay acts as a switch for the load's independent circuit.

Figure 5: Wiring Reference 2. This diagram illustrates the module powered by one supply, while the load is powered by a separate supply (DC or AC) through the relay's COM and NO terminals. A trigger switch (S1 Key) is also shown.

Instruccions de funcionament

The module supports two main operating modes: Mon (single trigger) and Cycle. The timing for "on" and "off" states is adjustable using the onboard potentiometers.

Selecció del mode

The operating mode is selected using a jumper on the module. Locate the jumper labeled "Mon" and "Cyc".

• Mon Mode (Single Trigger): When the jumper is on "Mon", the module operates in single trigger mode. Upon receiving a trigger, the relay will switch on, and after the set delay time, it will switch off. If triggered again during the delay process, the current delay will be interrupted and reset.
• Mode de cicle: When the jumper is on "Cyc", the module operates in cycle mode. Upon receiving a trigger, the relay will switch on for a set "on" time (T1), then switch off for a set "off" time (T2), and this cycle will repeat indefinitely until interrupted. If triggered again during the delay process, the current delay will be interrupted and reset.

Ajust de temps

The module features two adjustable potentiometers for setting the timing intervals. These are typically labeled for "on" time and "off" time, or T1 and T2 in cycle mode.

• Adjust "On" Time (T1): Use the potentiometer labeled "+OnT" or similar to set the duration the relay remains active.
• Adjust "Off" Time (T2): Use the potentiometer labeled "+OffT" or similar to set the duration the relay remains inactive (in cycle mode).

The time range can also be adjusted using a separate jumper, typically labeled "T" and "T/10".

• "T" Position: Normal time range.
• "T/10" Position: Time is divided by 10, allowing for finer adjustment within a smaller range.

Resolució de problemes

If you encounter issues with your Walfront Timer Relay Module, consider the following troubleshooting steps:

• El mòdul no s'encén:
  • Verifiqueu el vol d'entradatage matches the module's rating (5V, 12V, or 24V DC).
  • Check power supply connections for correct polarity (+ to +, - to -). Reverse polarity can damage the module.
  • Ensure the power supply is providing sufficient current.
• Relay Not Triggering/Switching:
  • Confirm the 'Key' input is correctly wired and the trigger signal is being applied (e.g., button press, short circuit).
  • In Mon mode, ensure the trigger is a momentary signal if continuous triggering is not desired.
  • Check the potentiometer settings; they might be set to a very short or very long duration.
  • Verify the mode jumper (Mon/Cyc) is correctly positioned for your desired operation.
• Inconsistent Timing:
  • Ensure the power supply is stable and free from significant voltage fluctuacions.
  • Check the "T" / "T/10" jumper setting to ensure the correct time scaling is selected.
  • Adjust potentiometers slowly and test to find the desired timing.
• Load Not Operating:
  • Verify the load's power supply is connected and functional.
  • Check the relay output connections (COM, NO, NC) to ensure the load is wired to the correct terminals for your desired operation.
  • Assegureu-vos del corrent i el volum de la càrregatage requirements do not exceed the relay's load capacity (10A, AC0-250V, DC0-30V).

Manteniment

The Walfront Timer Relay Module is designed for low maintenance. Follow these guidelines to ensure its longevity:

• Mantenir net: Periodically clean the module with a soft, dry cloth to remove dust and debris. Avoid using liquids or harsh chemicals.
• Condicions ambientals: Operate the module within its specified temperature and humidity ranges. Avoid extreme temperatures, direct sunlight, and high moisture environments.
• Connexions segures: Regularly check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Evita la sobrecàrrega: Do not exceed the specified load capacity of the relay (10A, AC0-250V, DC0-30V). Overloading can damage the relay and the module.
