DROK Time Delay Relay Twin Pack — DC 6–30V / AC 220V Programmable Timer Module with LCD & 0.01s–9999min Range

This twin-pack of DROK delay relay modules offers precise timing, flexible trigger options and reliable protection features for DIY electronics, automation prototypes, and simple power-control tasks. Each unit measures 7.1 × 3.9 × 2.5 cm and is rated to switch DC loads up to 30V/10A or AC loads up to 220V/5A. The module includes an LCD to show relay state, mode and countdown, a pause button for interrupting a cycle, UART support for parameter upload, and built-in safeguards such as reverse-connection protection and power-off memory.

How flexible is the timing and trigger control?

The module supports an extremely wide timing range from 0.01 seconds up to 9,999 minutes, letting you tune short pulses or long delays. Trigger options include high-level trigger, low-level trigger and passive switch control, covering most common interfacing needs with microcontrollers, sensors or manual switches.

• Timing range: 0.01s to 9,999 min continuously adjustable
• Trigger modes: high level, low level, and switching value (passive switch)
• Compatible input voltages: DC 6–30V for control logic

What electrical loads and protections does it support?

Each relay output will reliably switch small DC or AC devices within the stated limits, and the module includes built-in reverse-connection protection so wiring mistakes won’t immediately damage it. Typical use-cases include powering motors, lamps, solenoids or logic circuits within the load ratings.

• Output capacity: DC 30V/10A or AC 220V/5A
• Reverse-polarity protection avoids burnouts on incorrect wiring
• Long service life: rated for over 100,000 mechanical cycles

Which user controls and memory features help during setup?

The front panel combines a clear LCD with tactile buttons to change modes, pause an active cycle and view stored parameters without interrupting operation. All configuration settings are saved on power-down, and a sleep mode dims the backlight to save power until the next button press.

• LCD displays mode, relay status and remaining time
• Pause button for one-touch interruption of timing cycles
• Power-off storage preserves all parameters; sleep mode conserves backlight

How can these modules be integrated into projects and systems?

The DROK timer supports UART parameter upload for batch configuration and remote adjustments, making it suitable for repeated installations or programmable control panels. Because it accepts a wide DC input range and multiple trigger types, it integrates easily with microcontrollers, sensors, manual switches, or other control circuits.

• UART interface for data upload and remote parameter setting
• Works with microcontrollers (Arduino, Raspberry Pi) via trigger signals
• Compact footprint for mounting inside enclosures or racks

Who is this for: Engineers, makers, technicians and hobbyists who need a dependable, configurable delay relay for automation, testing, lighting control, robotics or prototype work. The two-module pack is ideal for projects that require matched timers or a spare module. Note: trigger cables or connectors are not included and must be purchased separately.
