Isolated DAQScalable modular system consists of a DAPserver with up to two DAP boards connected to eight input signal interface (SI) modules and two output SI modules in a 3U card-cage - all in the same enclosure. The input SI modules provide isolated analog inputs; all inputs are differential. The output modules provide isolated analog outputs. Channel-to-channel isolation eliminates ground currents, a potential source of noise in your measurements and in your output signals.Microstar Laboratories; 425/453-2345; www.mstarlabs.com
