Each DI-8B47 module isolates, filters, amplifies, and linearizes a single channel of temperature input from .. a thermocouple and provides an analog voltage output. Linearization is acplished using a four breakpoint piecewise linear approximation. The DI-8B47 can interface to industry standard thermocouple type J, K, and T and has an output signal of 0V to +5V. Each module is cold-junction pensated to correct for parasitic thermocouples formed by the thermocouple wire and screw terminals on the mounting backpanel. Upscale open thermocouple detect is provided by an internal pull-up resistor. Signal filtering is acplished with a three-pole filter optimized for time and frequency response which provides 70d B of normal-mode-rejection at 60Hz. One pole of this filter...
