Relais USB ALLNET ALL-USB-Relay-Android — relais d'interface USB pour appareils Android, contrôle des entrées/sorties

ALLNET ALL-USB-Relay-Android is a compact USB relay module designed for operation with Android devices. The unit connects to Android-compatible hosts via USB and provides both digital outputs to switch external circuits and digital inputs to monitor external signals. The module targets simple automation, remote control and testing tasks where a direct USB interface to a relay and input ports is required.

Advantages

The relay module offers straightforward USB connectivity for Android systems without requiring complex wiring. It combines multiple switching outputs and monitoring inputs in a single compact module, allowing control and status feedback over the same USB connection. The device is suitable for rapid integration into small automation projects and prototyping environments where reliable, low-voltage switching and signal detection are needed.

Suitable for

• Simple home or lab automation tasks controlled from an Android tablet or smartphone
• Remote control of low-voltage devices and circuits via USB
• Functional testing and development of IoT prototypes with USB relay switching
• Monitoring of digital input signals from sensors or external controllers

Key specifications

• Interface: USB connection compatible with Android host devices
• Functionality: Digital relay outputs for switching external circuits and digital inputs for signal monitoring
• Form factor: Compact module suitable for benchtop and embedded use
• Power: USB-powered operation, no separate power supply required for logic functions
• Compatibility: Designed to work with Android-based systems that support USB peripheral devices

How to use

Connect the ALLNET USB relay to the Android device using a compatible USB cable or OTG adapter if required by the host. After the host recognizes the peripheral, use an appropriate Android application or driver that supports USB relay control to configure outputs and read input states. Wire external loads and signal sources to the relay outputs and input terminals following safety guidelines for the voltage and current intended for switching. Ensure the connected devices remain within the relay’s rated limits.

Recommendations

Use the module for low-voltage switching and signal monitoring tasks. Confirm that the Android host provides USB OTG support and that any control application used has permissions to access USB devices. For reliable operation, avoid exposing the module to moisture, extreme temperatures, or voltages beyond the relay specifications and install it in a suitable enclosure when used in permanent setups.
