Victron GX IO-Extender 150 – Input Output Expansion Module for GX Devices

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.

Precise PWM and Relay Control

Four PWM output channels deliver 5 V signals with 8-bit precision at 1.5625 kHz, ideal for dimming lights or controlling motor speed. Two bi-stable latching relays offer efficient low-power switching for DC and AC loads, with ratings up to 3 A at 30 VDC and 0.5 A at 250 VAC. A galvanically isolated solid-state relay (SSR) handles DC loads up to 70 V and 4 A, supporting inductive and capacitive loads for battery management and heavy-duty switching.

Seamless Integration and Automation

Powered directly via USB, the GX IO-Extender 150 requires no external power supply, simplifying installation. It integrates natively with Victron's GX ecosystem and supports Node-RED for advanced, user-defined automation. Monitor and control all I/O points through the GX user interface, enabling real-time adjustments and system optimisation.

Compact, Durable Design for Harsh Environments

Measuring 123 x 67 x 23 mm and weighing 0.17 kg, the module fits easily into tight spaces. It supports wall or DIN-rail mounting with secure spring terminals. The operating temperature range of -20 °C to +50 °C ensures reliable performance in challenging off-grid, marine, and industrial settings.

WARRANTY

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.

If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.

Warranty

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the original end-user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead-acid batteries: 2 years from date of purchase by the original end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries: 3 years from date of purchase by the original end-user, with a maximum of 42 months from the Victron Energy invoice date. In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the current net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased by Victron’s direct customers, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before the expiration of the original term. Victron may ask proof that the product was still functional at the time of purchase of the extended warranty.

During the warranty period, Victron Energy will, at its discretion, repair, replace or (partly) credit the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation, and re‐installation.

  • Use in an inappropriate environment (dust, corrosive vapour, humidity, high temperature, biological infestation, etc.).
  • Breakage or damage due to lightning.
  • Connection terminals and screws destroyed or other damages, like overheating, due to insufficient tightening.
  • For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone other than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

This warranty and our warranty obligations thereunder (repair, replacement or credit) are the direct customer’s and, if applicable, the end-user’s sole rights and remedies and our sole obligations with respect to any defective and/or non-conforming product or breach of warranty and is subject to and without prejudice to the limitations of liability in this warranty.

Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

As a product requires service, it must be brought back to the place of purchase. In case no contact can be made with the merchant, or if he is either unable or not allowed to provide service, direct contact should be made with Victron Energy through the support section on Victron’s website.

In case Victron Energy replaces a product, it will own the replaced product. Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products.

If Victron Energy repairs or replaces a part of a product, its warranty term is not extended: the warranty will apply for the remaining term of the original warranty term. For example, if Victron Energy replaces a product with a 5-year warranty after 3 years, the warranty of this product will apply for another 2 years, with a minimum of 6 months.

All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages.

The foregoing limited warranty provided by Victron Energy is in lieu of any other warranties, express or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, of any kind whatsoever including, without limitation, warranties of merchantability or fitness for a particular purpose, with respect to any product. The above is without prejudice to the arrangement for consumers detailed above.
