DROK Programmable Timer Relay 2-Pack — DC 6–30V / 5V USB, LCD, 0.01s–9999min, 5A

The DROK Timer Relay is a compact, programmable time-delay and cycle relay (two-piece kit) that runs from DC 6–30V or 5V via micro USB and displays modes on an easy-to-read LCD.

This dual-pack relay module provides flexible timing from 0.01 seconds up to 9,999 minutes, multiple trigger options, and an LCD that shows current mode, runtime, and cycle count. It stores settings after power loss, supports sleep mode to reduce power draw, and carries a durable relay rated for up to 5A at DC 30V or AC 220V. The board accepts high- or low-level triggers or potential-free contacts and is suitable for automation tasks, timed control, and cycling loads where precise intervals are required.

How do I power and trigger the DROK Timer Relay?

The module accepts a wide DC input from 6V to 30V, and also supports a 5V micro USB power supply for convenient powering from phone chargers or USB supplies. Triggering can be done with a high-level signal, a low-level signal, or a potential-free contact, making it compatible with many control systems and sensors.

• Working voltage: DC 6–30V, or 5V via micro USB
• Trigger types: high-level (≈3.0–24V), low-level (≈0–0.2V), or potential-free contact
• Low standby draw: static current ≈15mA; running ≈50mA

What timing ranges and modes can I set?

The timer offers an expansive adjustable range from 0.01 seconds up to 9,999 minutes and supports several operational modes including delay, cycle timing, and runtime/cycle displays. Parameters can be edited independently for different output behaviors and are preserved automatically if power is lost.

• Timing span: 0.01s to 9999 minutes, continuously adjustable
• Modes include delay, cycle and runtimes with on/off control
• Parameters (OP/CL/LOP) saved automatically on power failure

How does the display, sleep mode, and user controls work?

An LCD panel shows the selected mode and live timing values; it includes controls for setting and toggling relay functions. The display backlight will automatically switch off after inactivity to conserve power, and any button press wakes the screen. You can also view current parameter values without interrupting operation.

• Clear LCD shows mode, runtime, and cycle counts
• Automatic sleep after 5 minutes; any key wakes the display
• Short/long press controls: SET, STOP, DOWN to toggle views and functions

Additional useful behaviors include a selectable auto-hibernation function to minimize power draw, a relay ON/OFF function toggle that changes how the relay conducts, and a parameter-view shortcut to see saved values while the timer runs. The relay is built for longevity with a rated service life of over 100,000 cycles.

Who is this for? If you need a versatile, compact programmable relay for DIY automation, timed lighting, irrigation sequences, motor cycling, or test fixtures, the DROK two-pack gives you durable relays with flexible triggers, long-range timing, and a battery-friendly sleep mode. It fits hobbyists, technicians, and small-scale integrators looking for repeatable timing control backed by an LCD interface and auto-save settings.
