DROK Time Delay Relay Module 2pcs — DC 6–30V Adjustable Timer 0.01s–9999min with LCD & Memory

DROK's two-pack digital time delay relay modules are adjustable DC/AC timer switches that run on 6–30V and deliver precise delays from 0.01 seconds up to 9,999 minutes with an easy-to-read LCD and tactile controls.

This compact relay module puts programmable timing, pause control and memory storage into a 7.1 × 3.9 × 2.5 cm case suitable for automation, DIY electronics, industrial control panels and appliance projects. The display shows relay status, chosen mode and the countdown; parameters are retained through power cycles and can be uploaded or changed over UART. Reverse-connection protection and a sleep backlight extend reliability in varied environments.

How configurable is the timing and trigger behavior?

The DROK timer supports a very wide timing window and multiple trigger types so it fits many applications. Timing is continuously adjustable from 0.01 seconds to 9,999 minutes, and you can choose high-level, low-level or button/switch trigger methods.

• Timing range: 0.01s to 9,999 minutes for short pulses or very long delays.
• Trigger options: high-level trigger (3.0–24V), low-level trigger (0.0–0.2V), or passive switch control.
• Independent parameter sets (OP, CL, LOP) saved separately for different functions.
• UART support for uploading and adjusting parameters from a host device.

What electrical loads and voltages can it handle?

The module runs on DC 6–30V and can directly control common DC and AC loads within its output ratings. Use it to switch DC circuits up to 30V/10A or AC loads up to 220V/5A, making it suitable for relays, motors, lights and actuators with matching specifications.

• Operating voltage: DC 6–30V for flexible system integration.
• Output capacity: controls devices up to DC 30V/10A or AC 220V/5A.
• Working current: about 50mA; standby (quiescent) current: about 15mA.
• Operating temperature range: −40°C to 85°C for harsh conditions.

What user conveniences and protections does the module include?

The design focuses on usability and durability, with features that simplify setup and protect the module from common wiring mistakes. The LCD and keys allow on-device configuration, and the unit can pause, sleep, and remember settings after power loss.

• Clear LCD shows mode, relay status and remaining time; backlight auto-sleeps to save power.
• One-button pause and the ability to view parameters without interrupting operation.
• Reverse connection protection prevents damage if power leads are swapped.
• Service life rated for over 100,000 operations and automatic parameter storage on power-off.

Who is this for? Hobbyists, technicians and engineers who need a small, reliable programmable time relay for control panels, prototyping, automation tasks or retrofit projects will appreciate this DROK module. It’s ideal when you require flexible timing, multiple trigger modes, low standby draw and memory retention. Note: trigger cables or connectors are not included, so plan to supply your own wiring and mounts for installation.
