Victron GX IO-Extender 150 – Expand Your GX System with Advanced Input/Output Control
Boost Automation and Control Capabilities with the GX IO-Extender 150
The Victron GX IO-Extender 150 is a powerful USB-powered I/O module designed to expand the capabilities of Victron GX devices. It adds versatile control and automation functionality, making it the perfect upgrade for advanced energy systems used in caravans, RVs, marine vessels, off-grid cabins, industrial setups, and tiny homes. With seamless integration via USB, it enables fast deployment without the need for external power sources.
Flexible Input and Output Options
This compact extender features 8 digital I/Os, which can be flexibly configured as 8 inputs, 8 outputs, or a mix of 4 inputs and 4 outputs. The I/Os are isolated from USB and have state-indicating LEDs for intuitive operation and diagnostics. The inputs support 3.8–5.5 V, while the outputs deliver 5 V with a maximum current of 4 mA, making them ideal for interfacing with sensors, contactors, or logic-level devices.
Key Applications and Features Include:
- 4-channel PWM output (5 V, 8-bit precision at 1.5625 kHz) for motor or light dimming control
- 2 bi-stable latching relays with resistive and inductive load support, allowing efficient low-power switching
- Solid State Relay (SSR) capable of switching DC loads up to 70 V and 4 A, including inductive or capacitive loads
- Node-RED integration for customizable automation routines and real-time monitoring via the GX user interface
- Wall or DIN-rail mounting with spring terminals for fast, secure, and clean installations
Durable, Compact Design Optimized for Versatile Environments
Housed in a robust form factor measuring only 123 x 67 x 23 mm and weighing 0.17 kg, the GX IO-Extender 150 is engineered for environments with space constraints. Its operating temperature range of -20 °C to +50 °C ensures reliable performance in harsh off-grid, marine, or industrial settings. The use of potential-free relays and LED indicators further enhances usability and safety for varied electrical configurations.
Perfect for Modular Off-Grid and Marine Energy Systems
Designed for seamless use in solar energy systems, battery management, and remote device control, the GX IO-Extender 150 stands out due to its USB power convenience, high configurability, and Node-RED support. It enables real-time automation of energy consumption and storage tasks, enhancing system intelligence while maintaining full Victron ecosystem compatibility.
Upgrade and Automate with Confidence
Whether you're building a smart RV energy system, controlling ventilation in a tiny home, or managing battery bank switching in a marine installation, the Victron GX IO-Extender 150 is the trusted solution for advanced I/O integration. Its low power consumption, high-speed switching capabilities, and programmable logic features make it a standout choice in the energy automation space.
Upgrade your vehicle or installation now to be smarter, more efficient, and ready for the future of intelligent energy management in caravan, RV, marine, off-grid, industrial, and tiny home applications.
