Measurement Computing's CIO-DAS-TC is a 16-channel thermocouple/voltage input board for the ISA bus. The board accepts seven different types of thermocouple input, J, K, E, T, R, S, and B. Its digital output is scaled for temperature in either degrees C or F. An onboard microprocessor handles all the control and math functions including: CJC (Cold Junction Compensation), automatic gain and offset calibration, scaling (voltage to temperature translation) and thermocouple linearization. This relieves the computer from performing all these functions. The analogue input section is electrically isolated from the computer.
The CIO-DAS-TC is shipped fully-calibrated from the factory with calibration coefficients stored in nonvolatile RAM. At run time, these calibration factors are loaded into system memory and automatically retrieved each time a different range is specified.
