The VME-3122B is the VME based member of the Abaco family of analog input/output products. Along with 16-bit digitizing resolution, programcontrolled gain, selectable conversion rate, and automatic scanning of sixty-four
differential or single-ended analog inputs, the VME-3122B provides exceptional dynamic range and analog input channel density. Various operating modes are supported, including autoscanning, data bursts and external synchronization.
This board is designed to interface directly with Abaco line of signal conditioning boards for digitizing the outputs from thermocouples, Resistance Temperature Detectors (RTDs) and strain gages.
Individual channel gains can be downloaded for use during scanning operations, or the board can be configured with a fixed gain that is common to all channels.
Multiple boards can be synchronized together to enable as many as sixteen boards to initiate each scan simultaneously. An Interval Timer, Bus Interrupter, Channel Counter and Midscan/Endscan flag simplify the monitoring of data within the dual port data buffer. The system applications that can benefit from the
VME-3122B capabilities include factory automation, process control, data acquisition systems, training simulators and laboratory instrumentation.
