Low-cost PC/104 A/D and D/A modules operate from -40° to +85°C yet don't require calibration June 16, 2010, Arlington, TX - Two new, low-cost PC/104-compatible analog I/O cards were announced today by WinSystems. The PCM-MIO-G-AD-1 is a 16-channel, 16-bit analog input card and the PCM-MIO-G-DA-1 is an 8-channel, 12-bit analog output card. Both cards also support 48-lines of digital I/O. These small, 90 x 96mm, expansion boards are designed to meet customer requirements for accurate analog and digital I/O over a -40° to +85°C operating temperature range. They are designed for industrial, medical, security, transportation, and Mil/COTS applications. Based upon Linear Technologies' precision converters and voltage references, these cards do not require calibration which results in quick, easy setup; plus it eliminates the necessity for readjustment and recalibration to installed units in the field. The input ranges for the PCM-MIO-G-AD-1 are 0-5V, ±5V, 0-10V and ±10 volts. Two independent, 16-bit A/D converters support up to 16 single-ended or 8 differential channels or various combinations of both. The conversion speed is 100K samples/sec. The PCM-MIO-G-DA-1 has eight independent, 12-bit D/A converters on board. The output voltage ranges are 0-5V, 0-10V, 5V, and 10V. All output channels are programmable and can be updated and cleared individually or simultaneously. Both the PCM-MIO-G-AD-1 and PCM-MIO-G-DA-1 boards have 48 lines of digital I/O individually programmable for input, output, or output with read-back. The lines are TTL-compatible and can sink 12 mA which supports direct connection to industry-standard, optically isolated AC and DC signal conditioners. Isolated signal conditioners protect, filter, and isolate the analog input and output signals from electrical transients. Both cards are supplied with free drivers for C, Linux, and Windows® XP Embedded which can be downloaded free of charge from the WinSystems' website. The cards require only +5V to operate and have on board, ultra-low noise power supplies and a low drift voltage reference which is critical for accurate measurements with up to 16-bits of 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. PRICING AND AVAILABILITY
