Description

This relay control module provides a single鈥慶hannel switching solution controlled through USB serial commands. It allows a computer or controller to turn connected loads on or off by sending simple serial instructions over a USB interface.

Built‑in USB‑to‑serial control circuitry enables direct connection to a computer without additional adapters. The module communicates using standard serial parameters, allowing control through common serial debugging or custom software.

Equipped with onboard overcurrent protection and relay diode protection to support stable operation during switching. These protection features help reduce electrical stress on the relay and connected circuits during operation.

Includes power and relay status indicator LEDs that provide visual feedback for module power state and relay activation. This helps with system monitoring, testing, and troubleshooting during development and integration.

Compact PCB layout with clearly labeled terminals supports easy wiring and installation. Suitable for automation control, device switching, testing systems, and computer鈥慶ontrolled power or signal switching applications.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for EC Buying products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
