4 Channel 5V Relay Shield Module
Description
- 5V 4-Channel Relay interface board, and each one needs 15-20mA Driver Current
- Equiped with high-current relay, AC250V 10A ; DC30V 10A
- Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)
- Indication LEDs for Relay output status
The 4 Channel 5V Relay Shield Module is a interface board. It is used to control various appliances, and other equipment with large current.
- 1 x 4 Channel Relay Module
Fonctionne très bien. Les bornes à vis de haute qualité comprennent les emplacements normalement ouverts, communs et normalement fermés. Opto-isolé. Sur la mienne, chaque bobine consomme environ 55mA à 5V. Les relais s'activent (et les LED sont allumées) avec l'entrée LOW et s'éteignent avec l'entrée 5V
Excellent quality
This is exactly what I wanted. Simple low voltage control for 4 standard 110V outlets (of course light duty use only). Direct control by parallel port data pins on old PC.
I bought one of these for use with an Arduino Uno, to switch various model railroad-related loads. So far so good!
I use this relay board because, the power required to activate relays is supplied by external power supply. I want to minimise the current load on the raspberry. I needed DPDT relays so i used two in parallele Very fast delivry

- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
- Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
- On-Demand Items * — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets, or contact us through our Support Center.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
