The Measurement Computing PCI-DAS6033 is a multifunction data acquisition board that combines analog input, analog output, and digital I/O capabilities for industrial and laboratory measurement tasks. Built around a 16-bit successive approximation converter, it delivers 100 kS/s single-channel sampling with software-configurable input ranges from ±10 V to ±0.1 V (bipolar) and 0 to 10 V to 0 to 0.1 V (unipolar). The board supports 64 single-ended or 32 differential analog input channels, two 16-bit analog outputs at up to 10 kHz update rate, and eight bi-directional digital I/O lines for relay and solenoid control. On-board signal conditioning includes three 16-bit counters (82C54), programmable analog triggering via ATRIG input, and flexible A/D pacing options using an internal 40 MHz timebase or external sources. DMA transfer with scatter-gather capability, 8 k sample RAM buffer, and up to 16 Meg post-trigger sample capacity enable efficient high-speed data capture. The configuration memory stores up to 8k channel, gain, and offset settings.
