Output Ports (Reed Relay)
Reed relays provide very high quality, long life, low current (ten Watts
maximum), dry-contact switch closures. Reed relays are not suited for high
current applications. They 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 energized individually by
writing a “1” to the proper port bit.
