DC 5V-36V Cycle Delay Timer Switch Relay Module LED Display

DC 5V–36V Trigger Cycle Delay Timer Switch Relay Module with LED Display

Take full control of your DC circuits with this versatile, programmable Cycle Delay Timer Switch Relay Module. Whether you need to automate motors, lights, LED strips, micro-pumps, solenoid valves, or other DC-powered devices, this compact module delivers precise timing from 0.1 seconds to 999 minutes — all adjustable on the fly via a clear LED display and intuitive push-button interface.

Made in Mainland China.

Key Features

• Wide Voltage Range: Operates on DC 5V to 36V, making it compatible with the vast majority of DC systems and projects.
• High Current Output: Dual-MOS parallel drive delivers up to 15A continuous current (400W) at room temperature; up to 30A with enhanced heat dissipation.
• Fully Adjustable Timing: Timing range from 0.1 seconds to 999 minutes, continuously adjustable with three selectable decimal-point positions for precision.
• Multiple Operating Modes: Choose from P1.1, P1.2, P1.3 (single-trigger modes), P-2 (delayed-on trigger), P3.1 & P3.2 (cycle/loop modes), and P-4 (signal hold mode) to match any automation scenario.
• Silent, Spark-Free Switching: Solid-state MOS switching produces no noise, no sparks, and no electromagnetic interference — far outlasting traditional electromagnetic relays.
• Optocoupler Isolation: Industrial-grade board with optocoupler isolation for enhanced noise immunity and system stability.
• Reverse Polarity Protection: Built-in protection prevents damage if power is accidentally connected in reverse.
• Emergency STOP Button: Instantly disable the relay output with a single key press for immediate circuit cutoff.
• Sleep Mode: Display auto-off after 5 minutes of inactivity (C-P mode) to conserve energy; any key press wakes it up instantly.
• Non-Volatile Memory: All parameter settings (OP, CL, LOP) are retained after power-down — no need to re-enter your configuration.

Technical Specifications

Operating Modes Explained

• P1.1: Trigger → relay ON for "OP" time → OFF. Re-trigger during OP is ignored.
• P1.2: Trigger → relay ON for "OP" time. Re-trigger resets the countdown.
• P1.3: Trigger → relay ON for "OP" time. Re-trigger immediately turns relay OFF.
• P-2: Trigger → relay OFF for "CL" delay → relay ON for "OP" time → OFF.
• P3.1: Trigger → relay cycles ON ("OP") / OFF ("CL") for "LOP" cycles. Re-trigger stops cycling.
• P3.2: Auto-start cycling ON/OFF continuously without any trigger signal. Cycle count settable via "LOP".
• P-4: Signal hold mode — relay stays ON while trigger signal is present; turns OFF after "OP" delay once signal is removed.

Parameter Reference

• OP — Relay ON (conduction) duration
• CL — Relay OFF duration
• LOP — Number of cycles (1–999; "---" = infinite loop)

Frequently Asked Questions

Q: What types of devices can I control with this delay timer relay module?

A: This DC 5V–36V relay module can control a wide range of DC-powered devices, including motors, LED lighting, DC water pumps, micro-pumps, solenoid valves, fans, and other electrical loads rated within DC 5–36V at up to 15A continuous (400W). It is ideal for DIY electronics, home automation, aquarium systems, irrigation controllers, and industrial control applications.

Q: How do I set the timer delay on this relay module?

A: Power on the module and it will display the current mode (default: P1.1). Long-press the SET button (2 seconds) to enter mode selection. Use UP/DOWN keys to select your desired mode. Short-press SET to begin adjusting parameters (OP on-time, CL off-time, LOP cycle count). Use UP/DOWN to adjust values, and short-press STOP to shift the decimal point and select your time range (0.1 sec–999 sec–999 min). Long-press SET again to save and return to the main screen.

Q: Will my timer settings be lost if the module loses power?

A: No. All parameter settings — including OP, CL, and LOP values — are automatically saved to non-volatile memory. Your configuration is fully retained after a power cycle, so the module resumes with the same settings the next time it is powered on.

Q: What is the difference between the cycle modes P3.1 and P3.2?

A: P3.1 requires an external trigger signal to start cycling — once triggered, the relay alternates between ON ("OP") and OFF ("CL") for the set number of loops ("LOP"), and a re-trigger stops the cycle. P3.2 begins cycling automatically as soon as the module is powered on, without needing any external trigger signal, and continues for the configured number of loops or indefinitely if set to infinite loop ("---").

Q: Does this module work with both 12V and 24V systems?

A: Yes. This adjustable timer relay module supports any DC voltage from 5V to 36V, making it fully compatible with 5V, 9V, 12V, 24V, and other common DC supply voltages used in automotive, robotics, industrial, and hobbyist applications.
