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.

Key Features

  • 8 configurable digital I/Os with LED indicators, isolated from USB
  • 4 PWM outputs (5 V, 8-bit, 1.5625 kHz) for dimming or motor control
  • 2 bi-stable latching relays for low-power switching of DC/AC loads
  • Solid-state relay for DC loads up to 70 V, 4 A, with inductive/capacitive support
  • USB-powered with Node-RED integration for custom automation
  • Wall or DIN-rail mounting with spring terminals for secure installation

Ideal Applications

This module is suited for expanding control in Victron-based systems, including battery bank switching, generator start/stop, tank level monitoring, lighting control, and ventilation management. It is particularly valuable in caravans, RVs, marine vessels, off-grid cabins, and industrial setups where space and power efficiency are critical.
