The Omega OMB-DAQ-54 Personal Daqs are full-featured data acquisition products that utilize the Universal Serial Bus (USB), which is built into almost every new PC. Designed for high accuracy and resolution, the 22-bit OMB-DAQ-54/55/56 data acquisition systems directly measure multiple channels of voltage, thermocouple, pulse, frequency, and digital I/O (the OMB-DAQ-54 does not have digital, frequency I/O). A single cable to the PC provides high-speed communication and power to the OMB-DAQ-54/55/56. No additional batteries or power supplies are required, except when using bus-powered hubs.
