The DaqBook/2000E is a multifunction data acquisition device that has a 16-bit, 200-kHz A/D, which can be expanded up to 256 channels. Thirteen ranges are built-in ranges, and the device also features 100% digital calibration. More than 30 different signal conditioning and expansion options are available for the /2000E, including options to measure thermocouples, strain gages, accelerometers, RTD’s, 4-20 mA, and much more. It includes four 10 MHz counters that can synchronously measure frequency and count pulses concurrent with analog measurements. Also, there are 40 digital I/O lines which can be synchronously read or updated along with analog and frequency measurements. The 40 TTL-level digital I/O lines can be expanded up to 272 channels, including options for optical isolation and relay closures for switching applications. Additionally, the 2 timer outputs are capable of generating square waves up to 1 MHz.
