01 — About

What it does

The RTC Timer Relay Module is a multifunction real-time clock based timing controller designed to automatically switch electrical devices ON and OFF at precisely scheduled times. Featuring a built-in RTC chip with 24-hour LED display, 5 programmable time periods, and 5 selectable operating modes, it enables reliable daily, weekly, or monthly automation for home, industrial, and DIY electronics applications.

Key features

  • Built-in real-time clock (RTC) with 24-hour LED display
  • Five programmable time periods (PE-1 to PE-5)
  • Five function modes (P-1 to P-5) for daily, weekly, and monthly scheduling
  • Relay output supports up to 10A switching capacity
  • Wide operating voltage range from 5V to 60V DC
  • Powered via terminal block or Micro USB 5V input
  • Built-in backup battery to retain time during power loss
  • Built-in buzzer for audible alerts (enable/disable selectable)
  • Auto display sleep mode to save power
  • Long relay lifespan rated over 10 million operations

Good to know

  • Set the initial date and time correctly before programming any schedule.
  • The CLE (stop) time/date must always be later than the OPE (start) time/date for correct operation.
  • Install the backup battery to retain time settings during power interruptions.
  • Do not exceed the rated relay switching current of 10A; use an external contactor for higher loads.
  • Select the correct operating mode (P-1 to P-5) based on whether scheduling is daily, weekly, or date-specific.
  • Ensure proper insulation and wiring when switching AC mains loads through the relay output.
