Curtiss-Wright / Systran IP-DAC128V-69 IndustryPack Digital-Analog Converter Module

The Curtiss-Wright/Systran IP-DAC128V-69 is a 128-channel IndustryPack digital-to-analog converter module delivering 12-bit resolution with eight selectable voltage ranges. Designed for precision analog output in industrial, laboratory, and military environments, this module integrates directly into VME and PC-based systems via standard carrier boards. Its modular architecture supports mixed I/O configurations while maintaining high-speed operation with zero wait-states and simultaneous write/read-back access.
