New Product – Expand your GX device with the new IO-Extender 150
Agnes Beersmans

Victron Energy introduces the GX IO-Extender 150, a compact expansion module designed to increase the number of inputs, outputs, and relays on an existing GX device. This long-awaited accessory offers a smaller and simpler alternative to adding an extra Cerbo GX.


Compact and easy to install

The GX IO-Extender 150 is powered and controlled directly via the USB port of your GX device. With spring-loaded terminals, connections are quick and secure—no hassle with cables or loose contacts. Need even more ports? Multiple extenders can be daisy-chained for added capacity.


Versatile connectivity

The IO-Extender 150 includes:

  • 2 latching relays for switching low-power AC and DC loads, which retain their state during power loss
  • 1 solid-state switch for DC loads up to 4 A
  • 8 configurable digital I/Os, adjustable via DIP switches as 8 inputs, 8 outputs, or a 4-in/4-out mix
  • 1 PWM output with four channels for precise control applications
