Today, WinSystems introduced its PCM-MIO, a high-density analog and digital I/O card that operates from -40° to +85° Centigrade. This PC/104-compliant card includes a 16 channel, 12-bit analog-to-digital (A/D) converter, 8 channel, 12-bit digital-to-analog (D/A) converter, and 48 lines of digital I/O. Its design is unique since it requires no trimpots for calibration of the analog circuitry to remain within its specifications. No onboard potentiometers to adjust results in quick and easy setup of analog systems needing accurate digitally controlled voltages. This also eliminates the need for a technician or field engineer to readjust or recalibrate the unit which saves both time and money. The PCM-MIO is supplied with free drivers for Linux, Windows(R) CE and Windows(R) XP Embedded, and ROM-DOS.
The analog section of the board has been carefully designed with ultra low noise power supplies and a low drift voltage reference which is critical for accurate measurements up to 16-bit resolution. Special layout techniques and low drift resistor networks are also used to maintain the precision, accuracy, and long-term stability of this board. There are no missing codes and the measurements are monotonic over the full temperature range from -40° to +85° Centigrade.
The input ranges are 0-5V, ±5V, 0-10V and ±10 volts. The board will support up to 16 single-ended or 8 differential channels or various combinations of both. It is available with either 12-bit or 16-bit A/D converters. Eight independent, 12-bit D/A converters are also on the board. The output voltage ranges are 0-5V, 0-10V, ±5V, and ±10V.
WinSystems’ PCM-MIO is compatible with isolated signal conditioners that will protect, filter, and isolate the analog input and output signals from electrical transients. There are many models available from 3rd party vendors to interface to a wide variety of voltage, current, temperature, position and other analog based instrumentation.
There are 48 lines of digital I/O individually programmable for input, output, or output with read-back. The lines are TTL-compatible and can source and sink 12 mA which allow them direct connection to industry-standard, optically isolated AC and DC signal conditioners.
The PCM-MIO measures 3.6 x 3.8 inch (90mm x 96mm) and is PC/104 compliant.
List price for the PCM-MIO-12 is $395 and delivery is stock to 3 weeks. For sales information, please list; WinSystems’ Application Engineering Group at 715 Stadium Drive, Arlington, Texas 76011, (817) 274-7553, e-mail firstname.lastname@example.org and Website http://www.winsystems.com.
