I/O Ports
The Neets Control – SieRRa has 3 I/O’s onboard. They can be used for external
keyboard, PIR (movement) sensor, keyboard lock, extra relays and so on.
The ports are not potential free, which means you will need external relays, if you
need to prevent e.g. ground loops.
When used as output they are active low (when the software says activated, the
pin are tied to GND through a FET transistor - also called open drain/collector
function). You can draw up to 24VDC/500mA.
When used as input the voltage has to be below 1 Volt DC to be accepted as LOW, and
above 4 VDC (but below 24 VDC) to be accepted as high.
