Model 3U VPX 68DT1

3U OpenVPX Multichannel Discrete I/O Board

96-Ch, Discrete I/O (0 to 60 VDC, 500 mA/Ch.)

 

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.

Backround Built-In-Test (BIT)

BIT continuously monitors the status of all I/O during normal operations and is totally transparent to the user. SBC resources are not consumed while executing BIT routines. This simplifies maintenance, assures operational readiness, reduces life-cycle costs and - keeps your systems mission ready.

One-Source Efficiencies

Eliminate man-months of integration with a configured, field-proven system from NAI. Specification to deployment is a seamless experience as all design, state-of-the-art manufacturing, assembly and test are performed - by one trusted source. All facilities are located within the U.S. and optimized for high-mix/low volume production runs and extended lifecycle support.

Product Lifecycle Management

From design to production and beyond, NAI’s product lifecycle management strategy ensures the long-term availability of COTS products through configuration management, technology refresh and obsolescence component purchase and storage.
