DESCRIPTION
Victron GX IO-Extender 150: Advanced I/O Expansion for GX Devices
Enhance System Automation with USB-Powered Digital and Relay Control
The Victron GX IO-Extender 150 is a compact, USB-powered expansion module that significantly increases the input/output capabilities of Victron GX devices such as the Cerbo GX. It provides flexible digital I/O, PWM outputs, latching relays, and a solid-state relay, enabling precise control and monitoring in off-grid, marine, RV, and industrial energy systems. With Node-RED integration, users can create custom automation routines for smarter energy management.
Flexible Digital I/O Configuration
Eight isolated digital I/O channels can be configured as inputs, outputs, or a combination of both, with LED status indication for quick diagnostics. Inputs accept 3.8–5.5 V signals, while outputs provide 5 V at up to 4 mA, suitable for interfacing with sensors, contactors, or logic-level devices. This flexibility allows the module to adapt to diverse control requirements without additional hardware.

Victron Energy Limited Warranty Policy
Direct Customers
Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.
End-Users
Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.
