Relay X1
Single 10A Relay
- Overview
- Commands
- Samples
- On-Module Code
A single 10 A / 250 V mechanical relay that powers itself from the DUELink bus — no external power supply needed. Switch it on or off with simple text commands over any supported interface.
Common uses: single-load switching, small prop control, classroom AC-load demos, simple home-automation projects.
For more channels at the same rating, see Relay P4 (4 channels, external 5 V) or Relay P16 (16 isolated channels, external 12 V).
Mains-voltage AC (110/240 V) can cause electric shock, fire, or death. Only wire live AC power if you are qualified to do so — otherwise have a licensed electrician make the connections, or use these relays only for low-voltage DC loads.

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
| Function | Description |
|---|---|
Set(v) | Activate the relay (1 on, 0 off). |
DVer() | This driver version. |
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.
There are two ways to use it:
Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.
Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.
Copy Library LinkCode that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.
- Script
- Arduino IDE
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
