The 24V Programmable Cycle Timer Relay Module is a versatile, programmable timing controller designed for automated repetitive switching of electrical devices. It combines a high-current relay with an adjustable cycle timer and trigger function, making it an ideal solution for applications requiring periodic on/off operation — from industrial automation to home automation and DIY projects.

The module operates from a 24V DC power supply, making it compatible with common industrial control voltages, 24V battery systems, and commercial equipment. The onboard high-current relay is rated for 10A at 250V AC or 30V DC, capable of directly switching lamps, motors, pumps, solenoids, and other loads.

The module’s primary function is cycle timing mode — the relay cycles between ON and OFF states at user-defined intervals continuously. This makes it perfect for applications such as flashing lights, periodic pump operation, intermittent fan control, and cycling test equipment. The ON time and OFF time are independently adjustable, giving you full control over the duty cycle.

In addition to cycle timing, the module features a trigger function that allows an external signal to start or reset the timing sequence. This makes it suitable for applications where the timing cycle should begin in response to an event — such as a sensor activation, a button press, or a signal from another controller.

The digital LED display shows the current time settings and operating status, making configuration straightforward. The onboard buttons allow you to adjust ON time, OFF time, and other parameters without any external programmer or computer. The screw terminals provide secure connections for power, trigger input, and relay output.

The module is widely used in industrial control, home automation, aquarium and hydroponics systems, lighting effects, motor cycling, and DIY timing projects. Its simple operation and versatile cycling capability make it suitable for both beginners and experienced users.

Whether you are automating a hydroponic irrigation system, creating a flashing light effect, or cycling a pump for aeration, the 24V Programmable Cycle Timer Relay Module provides a reliable, programmable solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.

Usage

Getting Started

  1. Connect power — Supply DC 24V to the power input terminals. Observe correct polarity.

  2. Connect the trigger input (if used) — Wire your trigger signal source to the trigger input terminals.

  3. Connect the load — Wire the device you want to control to the relay output terminals (NO/NC/COM).

  4. Configure the cycle time — Use the onboard buttons to set the ON time and OFF time for the desired cycle. The LED display shows the current settings.

  5. Power on and test — Apply power. The relay will begin cycling between ON and OFF states at the configured intervals.

  6. Test trigger function — Apply a trigger signal to start or reset the timing sequence.
