Know before you buy
The extender connects directly to your GX device via a standard USB cable. This single connection handles both data communication and power, keeping your installation clean and simple.
The unit features a dedicated solid switch specifically designed for DC loads. However, for very high-current applications, you should use this switch to trigger a larger external relay or contactor.
These 8 ports are fully configurable, allowing you to use them as either inputs for sensors or outputs for control signals. When paired with Node-RED, you can create custom logic to automate your system based on specific triggers or conditions.
Yes, the two included latching relays are ideal for advanced switching tasks where you want to maintain a state without constant power draw. They are excellent for managing external devices that need to stay in an 'on' or 'off' position.
No specialized tools are required. The device uses pluggable spring terminals, which allow you to securely connect your wires by simply pushing them into the terminal block.
Yes, the PWM output provides precise control, making it suitable for tasks like dimming LED lighting or adjusting the speed of compatible DC fans within your Victron ecosystem.
