DAQ usually means a means of inputting and outputting data from the real world. ( Data Acquistion ) using embedded, automation and computing systems. The common signals can be analog in and out - 0-10VDC, +/- 10VDC etc, 4-20mA digital out - TTL/CMOS, Open Collector, relay, SSR, FET digital in - TTL/CMOS, Isolated DC or AC, Dry contact timing out - on/off, pulse streams, PWM timing in - on/off, counting, gated for period or frequency quadrature encoder conditioned analog for strain gauges, RTDs, TCs, Thermistors etc Various interfacing means are used to connect DAQ devices to PCs, Controllers, Microprocessors, PACs and PLCs. The most common method is connecting to a PC/PAC/PLC/Controller's bus using one of the buses available - ISA, PCI, PCIe, PXI, cPCI, PCMCIA, Cardbus, CanBUS, ModBus, USB 1, 2, 3, Serial, etc Both Ethernet and increasingly Wireless connections to WiFi, Bluetooth and Zigbee. Another form is the new M2M GSM and 3G DAQ systems for remote DAQ. Below is a comprehesive listing of the world leading companies that make DAQ products.
