The OMG-PCI-DIO series provide 
32, 48, and 96-channels of buffered 
digital I/O emulating 8255s for 
industrial control applications. 10K 
pull up resistors are included on 
each port bit. 
Each board contains 8-bit I/O ports 
configurable as inputs or outputs. 
This gives the user the ability to 
customize the combination inputs 
or outputs as needed. In addition, 
the low order bit of the first port 
can be set to generate an interrupt 
for status monitoring applications. 
A special factory configurable 
interrupt feature allows the user 
to request conditional I/O 
combinations for interrupt 
generation. When the I/O 
combinations occurs, a hardware 
interrupt is triggered.
Software
The OMG-PCI-DIO 
includes drivers, utilities, 
and programming samples for 
Windows XP/SP3/VISTA/7 
32- and 64-bit) and Linux to aid 
in the development of reliable 
applications for the OMG-PCI-DIO 
family of digital I/O boards.
Connectors and Terminal Panels
All of the I/O signals are accessed 
through a standard 50-pin 
connector. The 32-channel boards 
contain one connector, the 48 
channel board contains two 
connectors and the 96 channel 
board has four connectors. 
OMEGA provides an optional 
OMG-TB07 terminal panel for wiring 
to the I/O connector. One terminal 
panel is required for each I/O 
connector. An OMG-CA167 is also 
needed for each terminal panel. 
The I/O connector is also 
compatible with industry standard 
relay racks. A OMG-CA135 cable 
can be used to connect each 
I/O connector to a relay rack.
