Abstract
A data acquisition circuit is disclosed which provides sampled input voltage signals generated in a hostile environment to an input device, for example, the input circuitry of a computer. The data acquisition circuit provides electrical isolation to prevent damage to the input circuitry caused by electrical transients and short circuits occurring in the hostile environment and is particularly useful for sampling input data from thermocouples because it eliminates the need for an isolated power supply normally used to detect broken thermocouples.
