DROK Timer Relay 2pcs — DC 6–30V LCD Time Delay & Cycle Controller, 0.01s–9999min, 5A

DROK's dual timer relay kit is a compact, programmable DC time-delay and cycle controller with an LCD screen, wide 6–30V supply range (or 5V micro-USB), and adjustable timing from 0.01 seconds up to 9,999 minutes.

This two-piece set provides a reliable way to add time-delay, pulse, and cyclic control to DIY electronics, automation projects, or machinery that accepts DC or low-voltage trigger signals. Each module shows current mode and settings on an LCD, supports high- and low-level triggering, saves parameters automatically on power loss, and includes power-saving sleep behavior. The relays are rated for common loads up to 5A on DC30V or AC220V (resistive), and the unit operates across a broad temperature range for workshop or field use.

How does the DROK timer relay work in typical automation setups?

The module accepts DC supply from 6–30V or a 5V micro-USB source and monitors trigger inputs (high, low, or potential-free contacts). Once triggered, the onboard MCU runs the selected timing program and changes the relay output according to the stored parameters, then displays runtime and cycle counts on the LCD.

• Supply: DC 6–30V or 5V via micro-USB
• Trigger types: high-level, low-level, or dry contact
• Timing: adjustable from 0.01s to 9,999 minutes
• Output: relay rated DC30V/5A or AC220V/5A

Which timing modes and settings can I control on this relay?

The DROK relay supports multiple operation modes including delay, pulse, and cycle patterns. Parameters such as OP, CL, and LOP are independently adjustable and saved automatically, allowing consistent behavior after power interruptions.

• Independent OP/CL/LOP parameter editing and storage
• P-5/P-6 modes allow runtime or cycle count display switching
• Short-press SET to view current parameters without changing operation
• Settings auto-saved on power failure for continuity

What power management and durability features should I expect?

The relay includes a sleep (low-power) function that turns off the LCD backlight after five minutes of inactivity; any button press wakes the unit. The mechanical/electrical relay is built for long service life and the board is rated to endure repeated cycles under normal conditions.

• Auto-sleep: backlight off after 5 minutes, wake on button press
• Manual hibernation toggle via long-press STOP
• Service life rated over 100,000 cycles
• Operating temperature: -40°C to 85°C for wide-environment use

How do I integrate the DROK timer relay into my project safely?

Confirm the relay's voltage and current ratings match your load, choose the correct trigger method, and power the module either from your system DC rail (6–30V) or the convenient 5V micro-USB input. Use the LCD and front buttons to configure OP/CL/LOP and test outputs before final installation.

• Verify load does not exceed DC30V/5A or AC220V/5A rating
• Choose trigger: high-level (3.0–24V), low-level (0–0.2V), or potential-free
• Use short-press buttons to preview parameters without interrupting operation
• Test relay behavior on bench before wiring into final system

Who this is for: Hobbyists, makers, and professionals who need a small, USB-friendly programmable timer for control tasks — from prototype automation, pump or fan cycling, timed lighting, to relay-driven sequencing in equipment. The dual-pack is ideal when two synchronized or independent timing channels are needed in a single project or across separate circuits.
