The OMG-USB-DIO Series contains 48 or 96 channels of buffered digital I/O emulating 8255s for industrial control applications. 10K pull up resistors are included on each port bit. The OMG-USB-DIO series contains 8 bit I/O ports configurable as inputs or outputs. This gives the user the ability to customize the combination of 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.

The OMG-USB-DIO Series includes drivers, utilities, and programming samples for Windows 98/ME/NT/2000/XP to aid in the development of reliable applications for the OMG-USB-DIO family of USB to digital I/O interfaces.

Connectors and Terminal Panels
All of the I/O signals are accessed through standard 50-pin connectors. The OMG-USB-DIO48 contains two connectors and the OMG-USB-DIO96 contains 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 cable is also needed for each terminal panel. The I/O connector is also compatible with industry standard relay racks. An OMGCA135 cable can be used to connect each I/O connector to a relay rack.
