VME-3125A

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)
