The PCI-DAS-TC and CIO-DAS-TC are extremely accurate, easy-to-use, 16-channel thermocouple input boards for the PCI and ISA bus respectively for an IBM or compatible PC. The DAS-TC boards utilize an on-board microprocessor to convert the input measurements directly into °C or °F as well as provide Cold Junction Compensation. Your PC is not burdened with the conversion overhead. The boards use an extremely noise immune V/F (voltage to frequency) analog to digital converter to assure quiet, accurate measurements. Software selectable sample rates of 50 Hz, 60 Hz and 400 Hz allow the user to select the sample rate that offers the best AC line noise rejection. The DAS-TC boards are shipped complete with a screw terminal board and a 5-foot shielded cable. The screw terminal board provides an isothermal block assuring that the cold junction temperature device and all of the screw terminals are at the same temperature, while the shielded cable helps protect the system from external noise. The analog input section of the board is completely electrically isolated from the computer. The 500 V isolation protects your computer if one of the systems thermocouples inadvertently comes in contact with high voltage (although the board’s front end may be damaged by these high voltages).
