PCM-MIO-G-AD-1/DA-1 boards

WinSystems is rolling out two new, low-cost PC/104-compatible analog I/O cards. The PCM-MIO-G-AD-1 is a 16-channel, 16bit analog input card and the PCM-MIO-G-DA-1 is an eight-channel, 12bit analog output card. Both cards support 48-line of digital I/O.

These 90mm x 96mm expansion boards are designed for accurate analog and digital I/O over a -40 to +85C temperature range, especially for industrial, medical, security, transportation and Mil/COTS applications. Employing Linear Technologies' precision converters and voltage references, these cards don't require calibration, which results in quick, easy setup and eliminating the need 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 10V. Two independent, 16bit ADCs support up to 16 single-ended or eight differential channels or various combinations of both. The conversion speed is 100KSps. The PCM-MIO-G-DA-1 has eight independent, 12bit DACs 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 12mA, 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. The PCM-MIO-G-AD-1 list price is $249 and the PCM-MIO-G-DA-1 list price is $279. For either of the products, delivery is from stock to three weeks.
