DROK 12V Timer Relay with LED Display — 0.1s–999min Delay, 4 Modes, Optocoupler-Isolated Output

DROK 12V Timer Relay is a compact, LED-display electronic delay switch offering four trigger modes and an adjustable timing range from 0.1 seconds to 999 minutes for automotive and small-control applications.

This DIN-friendly delay module combines a clear numeric LED display, button controls and optocoupler-isolated outputs to deliver reliable timing functions for vehicles, hobby electronics, industrial controls and automation experiments. It supports multiple trigger sources — including positive supply, push-button, PNP sensors and PLC signals — and stores settings after power-off so you won't need to reprogram typical setups. The relay is designed to resist electrical interference and to be straightforward for installers and makers who need accurate on/off delay behavior without complex configuration.

How does the DROK timer relay handle different trigger sources?

The unit accepts a variety of input types to start or stop timing cycles. With four selectable modes, you can configure it for on-delay, off-delay and related behaviors to match your control scheme. The optocoupler isolation on the output also helps avoid false switching from noisy inputs.

• Compatible triggers: positive supply, push-button, PNP sensor, PLC output.
• Selectable mode via onboard buttons for flexible timing logic.
• Isolation reduces interference when connecting to industrial sensors or vehicle electronics.

What timing range and precision can I expect?

This relay covers a broad timing span from very short pulses to long delays, making it suitable for tasks that require anything from millisecond-level timing to multi-hour waits. The on-panel LED readout displays the set value clearly so you can rapidly verify the interval. Fine adjustment lets you tailor durations precisely to your application needs.

• Timing range: 0.1 seconds up to 999 minutes for wide versatility.
• LED numeric display shows current set value for quick confirmation.
• Button controls permit quick increments and mode changes without external tools.

How reliable is it in electrically noisy environments?

The relay uses optocoupler isolation on its output and a design that improves immunity to common disturbances, which helps keep switching consistent in automotive and industrial settings. This reduces false activations caused by engine noise, switching transients or PLC environments. The saved-parameter feature also prevents accidental loss of your configuration after power interruptions.

• Output isolation via optocoupler minimizes interference-related mistriggers.
• Module stores settings automatically when power is removed.
• Robust electronics suited for vehicle and industrial control circuits.

How easy is it to install and operate the DROK relay?

Installation and operation are kept simple with labeled connection points, a compact PCB form factor and tactile buttons for mode and time adjustments. No external programming hardware is required: set the mode, enter the desired duration and the device remembers the parameters. The LED display provides immediate feedback so you can confirm and fine-tune settings on the bench or in the field.

• Onboard buttons and LED display for straightforward setup and verification.
• Compact footprint fits into many enclosures or dash panels for automotive use.
• Automatic parameter saving eliminates the need to reprogram after power loss.

Who is this for? The DROK 12V Timer Relay suits electricians, vehicle hobbyists, automation hobbyists, technicians and integrators who need a dependable, space-saving time delay solution with flexible trigger options. Choose this module when you want a broad timing range, clear visual feedback and improved resistance to electrical noise without spending time on complicated configuration or external controllers.
