Two new PC/104-compatible analog I/O cards have been developed 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 96 mm) expansion boards are designed to meet customer requirements for accurate analog and digital I/O over a -40°C to +85°C 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, as well as eliminating the necessity for readjustment and recalibration to installed units in the field.The input ranges for the PCM-MIO-G-AD-1 are 0–5 V, ±5 V, 0–10 V and ±10 V. Two independent, 16-bit A/D converters support up to 16 single-ended or eight differential channels or various combinations of both. The conversion speed is 100 KSps.
The PCM-MIO-G-DA-1 has eight independent, 12-bit D/A converters on board. The output voltage ranges are 0-5 V, 0-10 V, ±5 V, and ±10 V. All output channels are programmable and can be updated and cleared individually or simultaneously.Both 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 optically isolated AC and DC signal conditioners. Both cards are supplied with free drivers for C, Linux and Windows XP Embedded.
