The Measurement Computing/IOtech ADAC/5501MF is a PCI half-card data acquisition board delivering simultaneous analog input, output, and digital I/O in a single compact device. Built for high-speed industrial and scientific measurement, it combines 12-bit analog acquisition at up to 100 kHz with optional 16-bit analog outputs, 48 digital I/O lines, and dedicated counter/timer channels—all accessible through a single 68-pin SCSI III connector.
