The Victron Energy GX IO-Extender 150 expands the input and output capabilities of any compatible Victron GX device, letting you connect extra sensors, relays, and external equipment. It offers 8 digital I/Os (configurable as inputs, outputs, or a mix), a PWM output for precision control, and two latching relays for low-power switching.
Powered directly through USB, it installs easily with pluggable spring terminals and supports wall or DIN-rail mounting. Configure automation through Node-RED or control it from the Switch pane, making it ideal for expanding monitoring and control in off-grid, marine, and residential energy systems.
