Output Ports (Reed Relay)
Reed relays provide very high quality, long life, low current (10 Watt
maximum), dry contact switch closures. Reed relays are not suited for high
current applications, and can be destroyed by inductive load switching, where a
spark occurs across the contacts internally. The relays are normally open, and
close when energized. Each relay can be individually energized by writing a ‘1’
to the proper port bit.
