Victron GX IO-Extender 150

The Victron GX IO-Extender 150 expands the digital input and output capacity of compatible GX devices. It is designed for installers who need additional relay outputs or digital inputs on systems where the onboard GX I/O is already fully allocated. The unit connects directly to the GX device and is managed through the existing VenusOS interface.

Key Features

• Extends the I/O capacity of compatible Victron GX devices without additional controllers or software licences.
• Managed natively through VenusOS, so no separate configuration interface is required.
• Provides additional digital inputs for monitoring external signals such as generator run status, door contacts or tank level switches.
• Provides additional relay outputs for controlling external loads, alarms or generator start/stop circuits.
• Compact and lightweight at 0.18 kg, suitable for installation inside existing enclosures.
• SKU: BPP900800150 | GTIN: 8719076062882

Product Overview

GX devices such as the Cerbo GX ship with a fixed number of digital inputs and relay outputs. On larger or more complex installations, these are quickly consumed by generator control, tank monitoring, alarm outputs and external switching. The GX IO-Extender 150 addresses this by adding further I/O channels that appear within the same VenusOS environment, keeping system management centralised.

Because the extender integrates at the firmware level rather than as a third-party add-on, inputs and outputs are configured and monitored through the same menus used for the native GX I/O. This is particularly useful on commercial, marine or off-grid installations where multiple monitored inputs and controlled outputs are required from a single GX device.

Installation Notes

The GX IO-Extender 150 should be installed by a qualified electrician or experienced Victron installer. Verify compatibility with your specific GX device and VenusOS firmware version before installation. Connections to generator control circuits or external alarm systems must be made in accordance with the relevant wiring regulations. For systems connected to the grid, ensure all associated equipment remains compliant with G98 or G99 requirements as applicable.
