IOC-DAADIO-VME-A (Analog/Digital)

The IOC-DAADIO-VME board is a low cost, high functionality, analog/digital I/O product.

The board combines the functionality of digital-to-analog conversion (DAC), analog-to-digital conversion (ADC), and parallel input/output interface (PIO) on a double-height (6U) VMEbus board. Any of these functions (DAC, ADC, PIO) can be implemented singularly or in combination to tailor the board to specific needs.

DAC Module Features

• 8 voltage output channels
• 12-bit resolution per channel
• 5 mA drive capability (+/-10 V into 2 k Ohm)
• Multiplying DAC capability, that is, outputs may be scaled to external AC or DC reference signals
• Output voltage ranges independently jumper selectable as +/-10 V, +/-5 V,
• 0-10 V, 0-5 V, or unipolar or bipolar externally referenced (user supplied)
• Straight binary (unipolar), offset binary, or two’s complement (bipolar) input codes supported
• Remote sensing of output voltages (user selectable, per channel)
• Automatic 0 V output from Reset and Power-Up
• Output short circuit protection (indefinite duration - voltage and current outputs).

ADC Module Features

• 12-bit or 8-bit converter resolution, software selectable
• 32 input lines, configurable as 32 single-ended or pseudo-differential inputs, or 16 differential inputs
• Selection of 0-10 V, 5 V, and 10 V input ranges
• Selection of unipolar or bipolar voltage inputs
• Programmable gains of 1, 2, 4, 8, and 16 with gains of 10, 20, 40, 80, and 160
• 12 us A/D converter for high input sampling rate or 8 us A/D converter
• Pipelined architecture provides throughputs up to 160 kHz (with 8 us A/D)
• VMEbus interrupter signals end of conversion and pipeline empty
• Programmable interrupt levels
• 70 Vpp overvoltage protection
• Overvoltage error bit

PIO Module Features

• 48-bits of byte-wide
• Outputs tristate-able under software control
• 22 k pull-ups provided at all inputs
• I/O lines power-up (reset condition) as inputs pulled high
• Some I/O channels have programmable interrupt capability
• 24 mA output current sink
• Control register allows software enabling (disabling) of each of six byte-wide I/O port registered outputs.

Common Features
