1. Introduction
The GX IO-Extender 150 is a USB-connected expansion module that extends the available IO ports of GX devices such as the Ekrano GX and Cerbo GX.
It bridges the gap between your GX device and the external world, creating endless possibilities for monitoring, control, and automation.
1.1. Features
8 digital IOs, configurable as in two sets of four as inputs or outputs (via DIP switch).
4 PWM ports, 0 to 5V with 0,05 V steps for device regulation.
2 latching relays that maintain their state even if the power is lost.
1 solid switch with bat-, load, and bat+ connections for switching requirements.
The plug-and-play USB connectivity makes installation effortless. The GX IO-Extender 150 is simply plugged into an available USB port on the GX device and the inputs/outputs, PWMs and relays immediately become available to the system.
Whether you're managing a complex off-grid solar installation, a marine electrical system, or an industrial backup power solution, the GX IO-Extender 150 expands your ability to deliver on specific requirements:
Monitor additional sensors and equipment
Control external devices with precision
Automate complex system responses
Implement sophisticated control logic
The GX IO-Extender is not intended to be used for general load switching, but rather for signalling. The relays and solid switch have low current ratings that vary based on the voltage being used. Compatible products like those from Energy Solutions (UK), Garmin (USA) and Safiery, and others will be better suited for general switching applications.
