IOCADC4 ANALOG TO DIGITAL CONVERTER MODULE
■The IOCADC4 module is a 4 channel 10 bit analog to digital converter designed to receive analog signals and convert them to a digital binary representation. The resulting digital information is inserted into the PCM data stream defined by the IOCPCM2 module as part of an AL2873 Data Acquisition system. Data is inserted into the data stream MSB justified at a user selected word location and word interval for super commutated data words The 4 individual channels are inserted into the PCM stream in consecutive order (1-4) with channel 1 being inserted into the user selected word location. The user can selectively activate between 1 and 4 channels. Inactive channels are not inserted into the data stream.
■The IOCADC4 requires an IOCPCM2 module in an AL2873 chassis to be functional. The IOCPCM2 reads data from the individual acquisition modules over the AL2873 PCM bus and inserts the digital information into the user defined PCM data stream. Up to 13 IOCADC4 modules can be installed in a single AL2873 chassis providing up to 52 individual ADC channels. An additional 13 IOCADC4 modules can be configured in an expansion chassis expanding the number of analog channels per PCM stream to 104.
■Control of the IOCADC4 is via the front panel keypad and 3” x 2” LCD or Ethernet and the APEX software package. When configured, the current setup is retained in non-volatile memory and is automatically restored on power up with a recovery time of less than 20 seconds.
