9. DB-24POR
24-Channel Photo Output Board
The DB-24POR includes 24 normally open, form A, Photo-MOS relays. The
board interface to field logic signals, eliminating ground-loop problems and
isolating the host computer from damaging voltages. The user can use the
DB-24POR to switch load, up to 350VAC and up to 130mA, The relay is
energized by applying a 5 voltage signal to the appropriate relay channel on
the 50-pin OPTO-22 compatible connector or 37-pin D-sub connector.
Twenty-four indicators LEDs, one for each relay, light when their associated
relay is activated. Because there is a D-sub 37-pin connector on the board,
the user may use it to interface to any TTL output board. In other words, the
user may use it as a general-purpose photo-MOS relay output board.
