The DC 5.0V–60V 24H Time-Sync Relay Module is a versatile, programmable timing controller designed for automated switching of electrical devices based on real-time clock (RTC) schedules and programmable delay sequences. It combines a high-current relay with an onboard RTC, 5 programmable delay groups, and a digital display, making it an ideal solution for applications requiring precise time-based automation — from industrial control to home automation and agricultural irrigation.
The module operates from a wide DC 5.0V to 60V input range, making it compatible with 5V, 12V, 24V, 36V, and 48V systems, as well as battery-powered setups. 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 standout feature of this module is its real-time clock (RTC) with 24-hour time-sync capability. The onboard RTC maintains accurate timekeeping even when power is interrupted (with backup battery), allowing you to schedule relay operations at specific times of day. The module supports 5 independent programmable delay groups, each of which can be configured with:
-
ON time — when the relay activates
-
OFF time — when the relay deactivates
-
Days of week — which days the schedule applies
-
Delay duration — how long the relay remains active
This makes it possible to create complex automation schedules such as:
-
Daily lighting schedules — turn lights on at sunset and off at sunrise
-
Irrigation cycles — water plants at specific times on specific days
-
Equipment scheduling — activate machinery only during working hours
-
HVAC control — run heating or cooling systems on a weekly schedule
-
Security lighting — simulate occupancy with varied on/off times
The digital LED display shows the current time, day of week, and programming menu, making configuration straightforward. The onboard buttons allow you to navigate menus, set schedules, and adjust parameters without any external programmer or computer. The screw terminals provide secure connections for power and load.
The module is widely used in industrial control, home automation, agricultural irrigation, aquarium and hydroponics, lighting control, and DIY automation projects. Its RTC-based scheduling and multiple delay groups make it one of the most flexible timing modules available.
Whether you are automating a greenhouse irrigation system, scheduling equipment operation, or creating a custom lighting schedule, the DC 5.0V–60V 24H Time-Sync 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.
