OMEGA Engineering, Inc. USB Data Acquisition Module OMB-DAQ-54, OMB-DAQ-55 and OMB-DAQ-56

The OMB-DAQ-54, OMB-DAQ-55 and OMB-DAQ-56 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. The OMB-DAQ-54/55/56 modules are the first products in a new family of low-cost, USB-based products from OMEGA. Because of the strict power limitations of the USB, the modules incorporate special powermanagement circuitry to ensure adherence to USB specifications. The OMB-DAQ-54/55/56 avoid many of the limitations of PC-Card (PCMCIA) data acquisition devices and offer advantages over many PC plug-in data acquisition boards as well.
