The DAP 5216a/627 includes 16 analog inputs, 2 analog outputs, 16 digital inputs, and 16 digital outputs. External rack-mounted hardware can extend these channel counts to 512, 66, 128, and 1024 respectively. The board can acquire 16-bit data at up to 500k samples per second, and can convert one million values per second with 16-bit resolution on each of the two onboard analog outputs. The maximum digital input and output rates are both 2M samples per second on all sixteen channels each way, even when running concurrently. The onboard AMD K6-III+ processor allows fast real-time processing. Low latency — 0.1 ms task time quantum delivers fast response.
