Output Ports (Reed Relays)
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.
