This digital timer relay module delivers precise countdown and delay control for automated applications. The compact plastic housing features an integrated power supply switch for convenient operation. The dual-display digital interface shows both process value (PV) and set value (SV) with bright LED readouts - red digits for current time and green for your programmed setting. Four intuitive control buttons allow easy programming: up/down arrows for time adjustment, SET for configuration, and a power button for quick on/off control. The relay module design makes it perfect for controlling pumps, lights, fans, and other electrical devices in automotive, household, or DIY projects. Its accurate timing performance ensures reliable operation for tasks requiring precise time-based control, from workshop automation to garden irrigation systems.
