The Measurement Computing/Data Translation DT304 is a PCI bus multifunction data acquisition board delivering 16 single-ended or 8 differential analog inputs, 2 analog outputs, 23 digital I/O lines, and four user counter/timers in a compact form factor. Built for measurement and control applications requiring flexible channel configuration and high-speed synchronization, the DT304 combines software-calibrated analog acquisition with dynamic digital input time-stamping and bus-master data transfer.
