Chapter Seven:
GPIO xNode
The GPIO xNode provides 6 DA-15 ports. Each port provides 5 GPI (opto isolated inputs) and 5 GPO (solid state
relays). Each port is capable of driving a combined current of 100mA. Each GPI pin should be limited to 20mA of
current.
The web interface provides configuration control as well as a real time view on each of the GPI and GPO pins
through a Java script in the web interface.
