DROK 12V Timer Relay 2pcs — LED Display Time Delay Switch 0.1s–999min, 4 Modes

The DROK 12V Timer Relay is a compact LED-display time-delay switch offering four selectable trigger modes and an adjustable range from 0.1 seconds to 999 minutes for automotive and DIY control tasks.

If you need precise, repeatable on/off timing for automotive accessories, control panels, or automation projects, this two-pack of DROK timer relays delivers flexible timing, visible digital readout and simple button operation. The module accepts multiple trigger sources, isolates outputs with an optocoupler for interference resistance, and saves settings automatically when power is removed. Its wide timing span suits short pulses and long delays without extra components, making it a convenient building block for hobbyists, technicians and installers.

How can I use the four trigger modes in real applications?

This relay provides four selectable modes to fit common control scenarios: a power-on delay, a pulse-on trigger, a pulse-off trigger, and a latch-style configuration. Each mode responds to different input types—battery positive, momentary buttons, PNP sensors or PLC signals—so you can integrate the relay into vehicle circuits or control systems without rewiring the source.

• Mode options: on-delay, off-delay, single pulse, and latch-like operation.
• Compatible triggers: positive-power, push-button, PNP sensor, PLC outputs.
• Quick mode selection via front-button interface and LED feedback.

What timing accuracy and range does this delay module offer?

The DROK timer covers an extensive timing window from 0.1 seconds up to 999 minutes, letting you set rapid pulses or extended hold periods with a single device. The LED numerical display shows the configured duration clearly, and the digital control means repeatable timing without analog drift common to potentiometer timers.

• Adjustable range: 0.1 s to 999 min for versatile use.
• Numerical LED display for precise value confirmation.
• Digital control ensures consistent, repeatable timing.

Is the relay reliable in electrically noisy environments?

Yes—the relay output uses optocoupler isolation which reduces susceptibility to electrical interference and helps protect downstream circuits. That isolation, combined with the relay’s compact PCB design, improves stability when used near motors, pumps or automotive alternators that can generate transient noise.

• Optocoupler isolation on the output for noise immunity.
• Designed for 12V DC systems common in vehicles and small equipment.
• Compact PCB layout minimizes wiring length and stray coupling.

Who is this for?

The DROK 12V Timer Relay is suited to automotive DIYers, electricians, hobbyists and installers who need a dependable, easy-to-configure time-delay device for lighting, horns, pumps, gates, alarm circuits or test rigs. It’s also handy for prototype work and small automation tasks where a visible display, multiple trigger options and stored settings reduce setup time. If you want a small, economical relay module with broad timing flexibility and interference protection, this two-pack offers a ready-to-install solution.
