8. DB-24OD
24-Channel Open Drain Output Board
DB –24OD
The DB-24OD has 24-channel optically isolated digital output. The board is
the interface for field logic signals, elimination ground-loop problems and
isolating the host computer from damaging voltages. The DB-24OD has a
single 37-pin D-sub connector, one 50-pin OPTO-22 compatible male header
and a 20-pin male header. The transistor is powered by applying a 5-volt
signal to the appropriate input channel on the 50-pin header, the 20-pin
header or the 37-pin D-sub connector. Twenty-four indicator LEDs, one for
each transistor, are lit when their associated transistor is activated. The board
may be used to interface with any TTL output board, allowing it to be used as
a general purpose open-drain output board.
