Important note

The GX IO-Extender 150 is an official Victron accessory designed for use with all GX-series communication devices. It connects via USB and is powered through the USB cable, requiring no additional power source. The module’s I/Os are user-configurable, with DIP switches allowing you to select between input and output mode on each channel. As with all Victron gear, it is engineered to meet demanding power management and automation needs in marine, off-grid, RV and commercial setups.

We accept
This product is not vehicle-specific. It is compatible with any GX device-based system, whether installed in marine vessels, caravans, 4WD touring vehicles, off-grid homes, or commercial energy storage setups.

The Victron GX IO-Extender 150 expands the number of inputs and outputs available to a GX device, adding tank sender inputs, temperature sender inputs and digital inputs beyond what the GX itself provides.

It suits installations where the number of tanks, sensors or switched circuits exceeds the ports on the Cerbo GX or Ekrano GX.

It connects to the GX device and is configured through the same interface, so the additional inputs appear alongside the existing ones in VictronConnect and on the VRM portal.

Everything this install needs

0 of 0 in the box

The GX IO-Extender 150 is a plug-and-play unit that connects to your GX device via USB.

All power is supplied over USB. The 8 digital I/Os can be configured using DIP switches on the board. Each I/O has an indicator LED to show activity.

The 4 PWM outputs are factory-set to a 1.56 kHz signal with 8-bit resolution and can be used for fan speed or dimming controls.

The 2 latching relays are ideal for on/off switching and remain in their last state if power is lost.

The solid-state relay is designed for low-current DC control applications.

Mounting options include wall or DIN-rail mounting (DIN bracket sold separately).

Configuration is performed within the Venus OS interface.

User Manual

This product is not vehicle-specific. It is compatible with any GX device-based system, whether installed in marine vessels, caravans, 4WD touring vehicles, off-grid homes, or commercial energy storage setups.

Q: Can the GX IO-Extender 150 switch heavy loads directly?
A: No – all relays are signal level only. Use external relays for high-current switching applications.

Q: Do I need to install drivers?
A: No – the device is plug-and-play on any Victron GX system running Venus OS v3.60 or newer.

Q: What is the PWM signal used for?
A: PWM outputs are commonly used to control DC fan speeds or lighting dimming via compatible controllers.

Q: Can I use this with Node-RED?
A: Yes – the module is fully integrated with Node-RED and accessible via the GX device's web interface.
