Victron Energy - GX IO-Extender 150

The GX IO-Extender 150 enhances the input and output (I/O) capabilities of a GX device,enabling seamless integration with additional sensors, controls, and external devices. Itconnects via USB, which also serves as its power source, providing a simple and efficientexpansion solution. The device can be controlled using Node- RED on the GX device as well asthe Switch pane in the user interface.
Features

• 8 digital I/Os, configurable as 8 inputs, 8 outputs or 4 inputs +4 outputs
• PWM output for precise control applications
• Two latching relays for low-power switching
• A solid switchfor controlling DC loads that can be resistive, capacitive or inductive (such as the coil of a high-power contactor)
• Pluggable spring terminals for fast and secure connections
• Configurable via Node-RED for easy automation and custom logic

Technical Note: The digital outputs can source 4mA max. When driving 4mA, the voltage dropacross the internal series resistor (560 0) is 2.24V, which leaves only 2.76V @ 4mA for theoutput signal. Therefore, a driver like a transistor or FET is required to switch a relay with a digital output.
