Frequently Asked Questions

How do I wire the Victron GX IO-Extender 150?

The module connects via USB to your GX device. Use the spring terminals for quick, tool-free connections to sensors (e.g., float switches, temperature probes) and actuators. Refer to the manual for wiring diagrams.

How do I connect a tank level sensor to a Cerbo GX IO Extender?

Connect the tank level sensor (e.g., resistive or 0-10V) to one of the analog inputs on the IO Extender. Then configure the input in Venus OS to match the sensor type, and it will display in the VRM portal and on the GX screen.

Can the GX IO Extender control a generator automatically?

Yes, the relay output can be used to start/stop a generator based on battery voltage, tank levels, or schedules. You can automate this with Node-RED or the built-in relay automation in Venus OS.

Can I use Node-RED with the GX IO Extender?

Yes, Node-RED is integrated into Venus OS and can interact with the IO Extender to build custom automation logic, such as sensor-based control and alarms.

Great expansion module

This gives my GX system more inputs and outputs. I use it to monitor tank levels and control a bilge pump. Setup was easy via USB.

Works as advertised

It's a nice addition to the GX system. The configurable I/Os are useful. I just wish it had a few more ports, but it's fine for my needs.

Good but documentation sparse

The module works fine, but figuring out how to configure the I/Os took some research. The manual is a bit thin. Once I got it, everything worked well.

Excellent build quality

Typical Victron quality. The module feels solid and the connectors are good. It connects easily to my GX and I can now monitor my tank sensors remotely via VRM.

Nice, but pricey

It does what it says but at $43, it seems a bit much for what it is. However, it's a genuine accessory and works perfectly. I'm happy.
