Connects directly to any GX device via a standard USB cable, which eliminates the need for an external power supply
Features eight isolated channels that can be customised as inputs or outputs to suit specific monitoring needs
Equipped with two latching bi-stable relays and four PWM output channels for advanced automation and switching
Includes an isolated solid-state switch capable of handling loads up to 4 A and battery voltages up to 70 V DC
Built-in LEDs for every channel provide instant visual confirmation of the operational state for easier troubleshooting
Compact design supports either wall mounting or DIN-rail installation for professional and flexible system integration
Where to use it
The Victron GX IO-Extender 150 is the ultimate expansion tool for advanced energy systems, allowing you to significantly increase the monitoring and control capacity of your Cerbo GX or other GX devices. By connecting via a simple USB cable, this extender adds eight configurable digital inputs/outputs, two latching relays, and four PWM outputs, making it ideal for complex marine, off-grid, and RV setups that require additional tank level sensors, temperature probes, or automated fan and light control. Its compact, DIN-rail mountable design and isolated circuitry ensure a professional and safe installation, providing the extra flexibility needed to manage custom automation and detailed system data through the Victron Remote Management (VRM) portal.
