OVERVIEW

The PCM-ADIO is an intelligent PC/104-based analog input, analog output, and digital I/O board designed to meet customer demands for high-accuracy and high channel count analog I/O. Based on 16-bit analog-to-digital and 12-bit digital-to-analog converters, the PCM-ADIO includes unique features such as advanced automatic conversion control and buffers, automatic calibration for all input modes of operation, and jumperless selection for all analog input/output ranges.

Automated input configurations provide designers the flexibility to digitize inputs from many different sources with little or no external input signal conditioning. Input range selection, mode, calibration, and conversion rates are handled automatically on a channel-by-channel basis through a simple command structure.

This board targets industrial applications that require a variety of inputs from thermocouples, amplified bridges and monitored system voltages representing parameters such as temperature, pressure, acceleration, humidity, frequency, vibration, weight, flow rates and current. The PCM-ADIO operates over the industrial temperature range of -40°C to +85°C.
