PC Micro Based Data Acquisition System

PC Micro Based Data Acquisition System

PCDAS-1694 is a highly sophisticated but very easy to use data acquisition system with unlimited applications and use. The system employs PC with Add on cards & interface cards. The system can record, analyse, plot & save data in files for future reference using its powerful software. Almost all physical parameters can be measured, recorded, analysed using this system with suitable sensors. The Add on ADC card has 16 analog single ended channels, 16 isolated digital input, output channels & two analog output channels. The reference selection for ADC is through software. Individual channels also can have preselected references. The interface cards are housed in a spearate DIN Enclosure which is modular in construction. In short this system combines speed, precision & repeatability in low level measurements with full computation and analysis capabilities. This system provides highly capable, yet economical solutions to process control development, transducer measurements, production testing and signal analysis applications.
