DROK Programmable Timer Relay 2-pack — DC 6–30V / Micro USB 5V, 0.01s–9,999min, LCD display

This dual-pack of compact timer relays gives you a reliable way to schedule, repeat, or delay electrical switching in hobby, workshop, and light industrial projects. Each module features a clear LCD readout, multiple trigger modes (high/low/potential-free), auto-save of settings on power loss, and a sleep mode to conserve power. The relays handle DC up to 30V and AC up to 220V at 5A, and the modules are rated for over 100,000 operations across an extended temperature range.

How do I power and trigger the DROK timer relays?

Each relay accepts a DC supply between 6V and 30V, and can also run from a 5V Micro USB source for convenience. Triggers support high-level (3.0–24V), low-level (0.0–0.2V) and potential-free contact inputs, letting you wire them to a wide variety of sensors, switches, or control circuits.

• Power: DC 6–30V or Micro USB 5.0V
• High-level trigger range: 3.0V–24V
• Low-level trigger range: 0.0V–0.2V
• Optional potential-free contact for isolated switching

What timing modes and ranges can I use for automation?

The module supports flexible timing from very short pulses to very long delays: 0.01 seconds up to 9,999 minutes. You can set single delays, repeating cycles, and select relay behavior (normally-on or normally-off) to match your automation needs. Parameters are stored automatically so settings return after power interruptions.

• Timing span: 0.01s — 9,999 minutes (continuously adjustable)
• Cycle and delay modes with runtime/cycle display switching
• Relay function selectable: 'ON' conducts when triggered, 'OFF' does not
• Automatic parameter saving on power failure

How does the display and low-power behavior work in daily use?

A bright LCD clearly shows current mode and parameters; the backlight will turn off after five minutes of inactivity to conserve power, and any button wakes it. There’s also an automatic hibernation option you can enable or disable for extended low-power operation.

• LCD shows mode, set values, runtime and cycle counts
• Auto-sleep after 5 minutes; any key resumes display
• Manual hibernation toggle via long press of STOP
• Quick parameter view with SET button without disrupting operation

What electrical ratings and durability should I expect?

Each relay contact is rated up to 5A at DC 30V or AC 220V, suitable for many low-voltage automation tasks and small loads. The unit draws modest current in operation and low static current while idle, and it is designed for long life and wide-temperature environments.

• Max output load: DC 30V 5A / AC 220V 5A
• Working current ~50mA; static current ~15mA
• Operates from -40°C to 85°C for demanding environments
• Rated for more than 100,000 switching cycles

Who is this for: Makers, electricians, and small-system installers who need a compact, programmable time-delay or cycle controller that saves settings, works with common voltage sources including USB, and supports versatile trigger options. This two-pack is useful for parallel deployments, redundant setups, or testing multiple configurations without swapping modules.
