3U OpenVPX High Density Multifunction I/O Board

The 68CB6 is a Configurable Open Systems Architecture™ (COSA®) 3U OpenVPX™ board that is preconfigured with 10 different “inboard” I/O, measurement and communication functions. This Combination-function Board (CB) provides a full suite of some of the most common & useful function interfaces supporting many different applications. The 68CB6 features a wide but dedicated selection of functions: Standard Functionality Discrete I/O (DT1); Successive Approximation Register (SAR) ±100 V Analog-to-Digital (AD); Isolated High Voltage Analog-to-Digital (ADF); ±10 V Digital-to-Analog (DA); Thermocouple (TC1) or Resistance Temperature Detector (RT1); Full-bridge Strain Gauge (SG1); Transmission/gear box Chip Detection and Fuzz Burn (CD1);  LVDT-to-Digital linear (LD6) displacement (position) measurement, AC Reference Source output (AC2); CAN bus communication (CB8). The 68CB6 offers unparalleled programming flexibility, a wide range of operating characteristics, and a unique design that eliminates the need for external intermediate circuit considerations such as pull-up resistors or mechanical configuration jumpers. Inboard functions are software controlled and memory addressed, accessed in similar COSA® modular fashion to maintain seamless common NAI Software Support Kit & API/library structures.
