3U OpenVPX Multichannel Discrete I/O Board
68DT1 - North Atlantic Industries (NAI)
The 68DT1 is a 3U OpenVPX™ board featuring up to 96-Channels of Standard Functionality (SF) DT1 module-type or Enhanced Functionality (EF) DT4 module-type Discrete I/O functions [foptioned, factory configurable].48-Channels are dedicated as input (voltage or contact sensing with programmable, pull-up/pull-down current sources). An additional 24 or 48-Channels are programmable for either input or output (current source, sink, or push-pull) switching up to 500 mA per channel from an applied 3 – 60 V external VCC source (or sink to ISO-GND). The 68DT1 can sense broken input connections and whether an input is shorted to +VCC or to ground. Additional features of the DT4 EF are listed below. The 68DT1 offers unparalleled programming flexibility, a wide range of operating characteristics, and a unique design that eliminates the need for pull-up resistors or mechanical jumpers.

High Density I/O Boards
NAI offers, and continues to introduce, high density multifunction or combination-function I/O boards designed for a specific application or purpose. Based on the specialized application itself, from the interface connectors through the motherboard, to the specific function, these boards typically address I/O function integration challenges requiring higher current capacity, layout, and/or grounding requirements that are not available in our standard I/O boards. They are specifically designed for rugged defense, commercial aerospace, and industrial applications.
