From the D8 spec sheet at:
Analog Inputs
• Thermocouples:
User selectable type, direct connection,
linearization, reference junction compensation, reversed
and shorted T/C detection and upscale break protection
with output averaging.
• RTD: 2 or 3 wire, platinum, 100? @ 0°C, DIN curve.
Requires scaling resistors. See special inputs in ordering
information.
• Linear: current and voltage signals from linear transmitter
Input Range and Accuracy
Sensor Range (°C) Range (°F) Accuracy
Type B 66 to 1760°C 150 to 3200°F ±4.0°C
Type E -200 to 787°C -328 to 1448°F ±1.0°C
Type J -212 to 760°C -350 to 1400°F ±1.2°C
Type K -268 to 1371°C -450 to 2500°F ±1.3°C
Type R -18 to 1766°C 0 to 3210°F ±2.8°C
Type S -18 to 1760°C 0 to 3200°F ±2.8°C
Type T -268 to 399°C -450 to 750°F ±1.6°C
RTD -200.0 to 621.1°C -328.0 to 1150.0°F ±0.5°C
I don't have time to dig out the specifics, but there's some means of configuring it to take a thermocouple.
Do you know what type thermocouple you are working with?
