    Intelligent CPU Kernel

    VME-AIO16 is an intelligent VMEbus board, containing 6 or 16 analog differential inputs and is ideally suited for fast and flexible data acquisition. It includes all necessary components on a VMEbus 6U board and needs one slot.

     

    The AIO16 contains a local MC 68340 CPU at 25 MHz for the execution of complex data acquisition algorithms. The CPU section of the AIO16 contains 256 kbytes of SRAM, EPROM and two RS-232 interfaces. Configuration parameters may be stored in an EEPROM.

     

    AIO16 contains 256 kbytes of shared SRAM, as well, to form the interface between local CPU and VMEbus.

    Powerful Analog Inputs

    Designed for use of A/D converters with 16 bits resolution, the AIO16 can also be equipped with 12 bits resolution converters. The input voltage range with standard components is ±10 V. By varying the resistance values, other voltage ranges as well as current measurement (±20 mA) are possible. The A/D converters synchronize via an external trigger signal or via software.

     

    The included software allows you to obtain the following sampling rates: the maximum sampling rate from trigger signal to reception of the A/D-data in the SRAM is 33 kHz when sampling all 16 channels synchronously. If sampling only 8 channels synchronously, the maximum sampling rate is 40 kHz, for just one channel it is 45 kHz.

    Analog Outputs

     

    In addition to the analog inputs, the AIO16 board contains 4 bipolar ±10 V D/A converter outputs with a resolution of 16 bits. These D/A converters allow internal calibration and offset adjustment of the input amplifiers. Connect each D/A converter to one of four A/D inputs via a multiplexer for this result. Of course, the user can also use these D/A converter outputs directly as process outputs.

    Electrical Isolation

    The VME-AIO16 has full electrical isolation of all analog inputs and outputs, proper wiring to the backplane via P2, an integrated power supply with DC to DC converters and LED displays on the front panel that make it ideally suitable for industrial use.

    Software Support

    esd electronics, Inc. supplies a complete operation package as firmware for the local CPU. It contains a shared RAM interface and complete parameter settings for sample rate, trigger condition etc.

     

    The multi-channel shared RAM interface makes the implementation of different master operating systems, such as VxWorks, OS-9, PSOS, UNIX, or RTOS-UH easy to realize. C drivers for various operating systems are available.
