ESD VME-AIO16 CPU Board - CPU 68340, 25 MHz, 256 kbytes SRAM, 16 A/D channels (16 Bit), UIN = ±10 V, 4 D/A channels (16 Bit)Max. sample rate 45 kHz (only one channel used) Simple Type: CPU Board

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. 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. 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.
