The VMIVME-7750-734 (legacy reference: VMIVME-4140) is a high-density analog output board from GE Fanuc designed for VMEbus-based control and simulation systems.
This module provides 32 independent analog output channels to convert digital control signals into precise analog commands for field devices such as servo valves, motor drives, and instrumentation loops. It uses 12-bit DAC resolution to ensure stable, low-noise signal generation with high linearity, making it suitable for precision control and testing environments.
The board follows the IEEE-1014 VMEbus standard, enabling compatibility with legacy VME control systems commonly used in aerospace, simulation, and industrial test platforms.
