The DA16-4D(PC) functions as a digital-to-analog conversion interface between a host PC and external analog devices. It converts digital data from the computer into corresponding analog voltage signals across four output channels. Each channel can be configured for either bipolar (±10 V) or unipolar (0–10 V) operation, enabling compatibility with a wide range of actuators, control systems, and measurement instruments.
The card’s 16-bit resolution allows for 65,536 discrete output levels, providing fine control over analog signal generation. The 75 kS/s sampling rate ensures smooth waveform output and responsiveness in dynamic control applications such as waveform synthesis, servo control, and process automation.
The dual 16-bit timers can be used for precise timing control, periodic signal generation, or synchronization with other system events. The card supports DMA (Direct Memory Access) for high-speed data transfer without burdening the CPU, and interrupt-driven operation for efficient event handling.
