Isolated Scanning 12-bit 32-Channel Analog-to-Digital Converter Board (6U) with Built-in-Test (BIT)

VME-3125A Analog-to-Digital Converter Board


Isolated Scanning 12-bit 32-Channel Analog-to-Digital Converter Board (6U) with Built-in-Test (BIT)

Applications: Instrumentation, Isolated Analog Inputs, Isolated Transducer Inputs, Ground Loop Elimination, Data Acquisition Systems, Medium-Rate Voltage Monitoring, Process Monitoring, Temperature Monitoring

  • 1,000 V analog GND/digital GND isolator
  • Low pass input filters: 50 kHz, optional 40 Hz
  • Pull-down resistors prevent floating inputs
  • Overvoltage protected inputs
  • Selectable data coding offset binary or two's complement
  • Input connector compatible with both discrete wire and ribbon cables
  • Jumper-programmable gains of x1, x10, x100
  • Selectable A/D ranges of +/-5 V, +/-10 V, 0 to +10 V
  • Supports real-time Built-in-Test
  • 40 kHz aggregate conversion rate
  • Input ranges from +/-50 mV to +/-10 V
  • Autoscanning continuously digitizes inputs and stores results in dual-ported data registers
  • 32 single-ended or 16 differential inputs
  • One 12-Bit A/D converter with built-in-track and hold
  • No software initiation required to begin scanning
  • Halt and lock scanning feature which enables ability of 40 KSPS of any channel (based on channel pointer)
