6-30V 1-Channel Power Relay Module with Adjustable Timing Cycle

6-30V 1-Channel Power Relay Module with Adjustable Timing Cycle & LED Display

This 1-Channel Power Relay Module is designed for home automation, delay timers, and control switch applications. It operates within a voltage range of 6V to 30V and also supports micro USB 5V power input. Featuring an adjustable timing cycle, digital LED display, and multiple operating modes, this module is ideal for DIY electronics, timing control systems, and industrial automation.

The relay output supports devices up to DC 30V 5A or AC 220V 5A, making it suitable for a wide range of applications, such as smart home devices, delay timers, and automated control projects.

Key Features:

• Adjustable Timing Cycle: Supports precise timing settings from 0.1 seconds to 999 minutes.

• Digital LED Display: Easy-to-read display for real-time operation.

• Flexible Power Supply: Operates on 6V-30V DC or 5V Micro USB.

• Wide Output Capability: Controls devices up to 30V DC 5A or 220V AC 5A.

• Multi-Mode Operation: Multiple timing modes (P1–P4) for versatile automation control.

• Compact Design: Ideal for integration into DIY and professional projects.

Operation Modes:

1. P1: Trigger signal → Relay ON for “OP” time → Relay OFF.

   • P1.1: Retriggering has no effect during the “OP” time.

   • P1.2: Retriggering restarts timing.

   • P1.3: Retriggering stops timing and relay turns OFF.

2. P2: Trigger signal → Wait “CL” time → Relay ON for “OP” time → Relay OFF.

3. P3.1: Trigger signal → Relay cycles between ON (“OP”) and OFF (“CL”) for set number of cycles (“LOP”).

   • If triggered during a cycle, relay stops.

4. P3.2: Relay cycles automatically after powering up without trigger input.

5. P4: Signal holding mode – Relay stays ON while signal is present; after signal disappears, relay turns OFF after “OP” time.

Timing Parameters:

• OP: Relay ON time.

• CL: Relay OFF time.

• LOP: Cycle count (1–999, “—” for unlimited cycles).

• Time Intervals:

  • xxx (No decimal) = Seconds (1–999s).

  • xx.x (One decimal) = 0.1s increments (0.1–99.9s).

  • x.x.x (Two decimals) = Minutes (1–999min).

Parameter Setting:

• Mode Selection: Long press SET for 2 seconds, use UP/DOWN keys to select mode (P1.1 – P4).

• Parameter Adjustment:

  • Short press SET to configure OP, CL, LOP values.

  • Use UP/DOWN for quick or unit adjustments.

  • STOP button selects decimal point placement and time intervals.

• Save Settings: Long press SET to save and return to the main screen.

• Display Status:

  • “000” = Idle (no decimal point).

  • Decimal point visible = Relay active.

Applications:

• Home Automation – Delay timers, smart devices.

• Industrial Control – Automation of equipment.

• DIY Electronics – Timing and switching projects.

• Motor & Pump Control – Delay start/stop functionality.

How to use :

Relay Module – Mode Select, Sleep Mode, and Key Features

This multi-functional relay module offers an easy-to-use interface with adjustable timing parameters (OP, CL, LOP) and advanced control options. Designed for automation, delay control, and DIY projects, it includes optocoupler isolation, wide voltage support, and a simple interface, making it reliable and user-friendly.

Mode Select Interface:

• Enter Mode: Press and hold the SET key to access the mode settings. After adjustments, long-press the SET button to return to the main interface.

• Activate Relay Mode:

  • ON: Relay remains connected during the set “OP” time.

  • OFF: Relay is disabled and won’t connect.

  • Quick Toggle: In the main interface, short press the STOP button to turn the relay ON or OFF. The current state will flash before returning to the main screen. (This acts as an emergency stop with a single button press.)

Sleep Mode:

• C-P Sleep Mode: If no operation occurs within 5 minutes, the display automatically turns off while maintaining the programmed functions.

• Mode Change:

  • Press and hold STOP for 2 seconds to toggle between C-P (Sleep Mode) and O-d (Display Always On).

  • The current state flashes and then returns to the main interface.

Notes:

• The relay contact is passive and works as a single-channel on/off controller.

• Parameter settings (OP, CL, LOP) are independent and saved even when the power is off.

Key Features:

• Optocoupler Isolation: Enhances anti-interference ability for stable performance.

• Memory Retention: All parameters are saved automatically after power loss.

• Wide Voltage Range: Supports 6–30V DC input and micro USB 5V power supply.

• Emergency Stop Function: Dedicated STOP button for quick relay shutdown.

• Reverse Polarity Protection: Prevents damage due to reverse wiring.

• Sleep Mode: Auto display-off after 5 minutes of inactivity, with a button press to wake up.

• User-Friendly Interface: Clear and powerful interface that meets diverse application needs.
