PCM-MIO-A-1 PC/104 – 16 ADC, 8 DAC, and 48 Digital I/O

The PCM-MIO-A-1 is a versatile, PC/104-based analog input, analog output, and digital I/O board designed for high-accuracy and high-channel-count analog and digital I/O. The board is based upon Linear Technology’s precision converters and voltage references which require no external calibration. The digital I/O utilizes WINSYSTEMS’ versatile WS16C48 Universal I/O controller functionality, also available on many of our SBCs and other I/O products.
