Introduction
The Victron Energy GX IO-Extender 150 is a versatile USB-connected expansion module that significantly increases the input/output (IO) capabilities of Victron's GX devices, such as the Ekrano GX and Cerbo GX. This device acts as a crucial bridge, connecting your GX system to the external environment and unlocking a wide array of possibilities for advanced monitoring, precise control, and sophisticated automation.
Key Features
- 8 Digital IOs: Configurable in two sets of four, these ports can function as either inputs or outputs via simple DIP switch settings, offering flexibility for various sensing and control tasks.
- 4 PWM Ports: Designed for precise regulation, these ports operate within a 0 to 5 V range with fine 0.05 V steps, suitable for applications like LED dimming or motor speed control.
- 2 Latching Relays: These bistable relays maintain their state even during power interruptions, ensuring critical functions remain set.
- 1 Solid Switch: Equipped with dedicated connections for battery positive (BAT+), load, and battery negative (BAT-), this switch is ideal for robust load switching requirements.
Installation is streamlined thanks to its plug-and-play USB connectivity. Simply connect the GX IO-Extender 150 to an available USB port on your GX device, and the new inputs, outputs, PWMs, and relays are immediately recognized and available within the system. This expansion module is particularly useful for managing complex off-grid solar installations, marine electrical systems, and industrial backup power solutions, allowing for the monitoring of additional sensors, precise control of external devices, and the implementation of complex control logic.
It is important to note that the digital outputs are intended for signaling purposes rather than directly switching high-power loads. For general load switching applications, it is recommended to consult compatible products from manufacturers like Energy Solutions (UK), Garmin (USA), and Safiery, as the relays and solid switch on the GX IO-Extender 150 have specific low current ratings.
For detailed installation and software integration, including configuration with Node-RED, please refer to the official Victron Energy documentation and the Venus OS Large documentation available at Victron Energy Live.
