Abaco Systems / SBS / Greenspring IP-DAC D/A Converter IndustryPack

The IP-DAC is a Type II IndustryPack D/A converter module delivering 16-bit resolution and high-fidelity analog output for precision voltage control applications. Each module supports up to 64 DAC channels per 6U VME slot through low-profile surface-mount design. The IP-DAC excels in multi-channel systems via master/slave architecture - one master can synchronize up to 32 slave modules via RS-485, scaling to 528 total channels with simultaneous update capability at rates up to 10 kHz.
