Vszerda 2Pcs DC 5V Delay Relay Module Adjustable Timer 0.1S-1H 10A

SKU CH-AAWA-KP75G

Two 5 V timer relay modules switch loads up to 10 A at DC 30 V or AC 250 V with adjustable delays from 0.1 s to 1 h

  • Adjustable delay from 0.1s to 1h covers diverse timing needs
  • 10A switching capacity handles DC 30V or AC 250V loads
  • Relay rated for over 100000 cycles ensures long service life
  • Anti-reverse protection diode safeguards the module from wiring errors
  • Compact 57*30*18.5mm board with 52*25mm mounting holes fits tight spaces

Vszerda 5V Adjustable Delay Relay Module

This pair of DC 5V relay modules provides timed switching for smart home, automotive and industrial control projects. Each board accepts a 5 V supply drawing 2.5 mA static and up to 70 mA when active, making it suitable for low-power microcontroller or PLC outputs. The adjustable potentiometer sets delays from 0.1 s to 1 h for flexible timing sequences.

10 A Load Capacity With 100 000 Cycle Life

Contacts handle DC 30 V or AC 250 V at 10 A, giving ample headroom for motors, lamps, GPS start protection or driving recorder circuits. The relay is rated for over 100 000 mechanical cycles, so repetitive automation tasks remain reliable. Maximum switching frequency reaches 5 kHz, limiting use to slower control loops rather than high-speed signal routing.

Double Sided FR-4 PCB With Jumper Selectable Modes

The 57 × 30 × 18.5 mm boards use double sided FR-4 with 52 × 25 mm mounting holes for secure chassis fixing. Jumper caps S6 and S7 select between power on delay start or trigger based timing, changing whether the common terminal connects to normally open or normally closed contacts after the delay. An anti reverse power protection diode guards against accidental polarity reversal.

Questions about this item

Will the 5 V 10 A relay module work with my existing 5 V microcontroller board?

Yes, the module runs on a 5 V supply drawing only 2.5 mA idle and 70 mA when active, so most 5 V logic boards can drive it directly.

How do I verify the adjustable timer is functioning after wiring the module?

Apply 5 V power, turn the potentiometer, and watch the relay click — the delay can be set from 0.1 s up to 1 hour before the contacts switch.

What comes in the pack and do I need extra jumper caps for the S6 and S7 headers?

The pack contains two 57 × 30 × 18.5 mm relay boards weighing about 22 g each with 52 × 25 mm mounting holes; jumper caps for S6/S7 are not included.
