DROK 12V Timer Relay with LED Display — 0.1s–999min Adjustable 4-Mode Time Delay (Optocoupler Isolated)

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

Designed for vehicles, automation projects, and control panels, this 12V relay module combines a clear digital readout with simple button controls and wide timing flexibility. It accepts common trigger sources (positive supply, push-buttons, PNP sensors, PLC outputs) and stores settings after power-off, so it’s useful for repeated timed switching without reprogramming. The relay’s optocoupler-isolated output improves resistance to electrical interference for more reliable operation in noisy environments.

How do I set the timer and switch between modes?

Setting the DROK timer is done using the built-in buttons and the LED numeric display. Navigate the menu to pick one of four timing modes, then adjust the time value directly; the module saves your parameters automatically when power is removed so your configuration remains intact.

• Use buttons to enter mode selection and timing value screens
• Choose between 4 available timing modes for different trigger behaviours
• Set time from 0.1s up to 999 minutes using the digital interface
• Power off to store settings automatically without extra steps

What trigger sources and wiring options work with this relay?

The relay accepts multiple trigger types so it integrates easily into existing systems. Typical compatible sources include positive-side battery signals, mechanical buttons, PNP-type sensors, and PLC outputs; follow the wiring diagram for correct power and input connections to avoid miswiring.

• Accepts positive supply trigger, push-button, PNP sensor, and PLC signals
• 12V DC power supply requirement common in automotive and control circuits
• Optocoupler-isolated output reduces influence from electrical noise
• Refer to supplied pinout diagram for safe, reliable wiring

What timing precision and range can I expect for different tasks?

This module covers a very wide timing span — from quick pulses to long delays — making it versatile for short-cycle operations or extended hold times. The resolution is sufficient for most control and automation uses, and the LED display helps you confirm and fine-tune the chosen interval.

• Adjustable range: 0.1 seconds up to 999 minutes for broad use cases
• Minute and sub-second precision suitable for timing lights, motors, or valves
• Clear LED display shows the selected delay value for rapid verification
• Stable output behavior maintained by isolation against interference

Who is this for? The DROK 12V Timer Relay is aimed at automotive hobbyists, technicians, and makers who need a reliable, easy-to-configure time-delay switch for lighting, fans, pumps, alarms, or automation experiments. It’s a practical choice for anyone building or repairing 12V systems that require repeatable time control, especially where space is limited and interference resistance matters. If you want a straightforward module with multiple trigger options, wide timing range, and memory for saved settings, this relay is a compact, cost-effective solution.
