Thermocouple measurements utilize a single cold junction compensation
sensor placed in the center of the terminal block. Thermocouple support
includes types J, K, T, E, R, S, B, N, C with a range to 100 mV. In
thermocouple mode the 1769sc-IF8u will measure thermocouple and CJC
sensor voltages and convert the results to a linearized temperature
reading. RTD support includes types Pt 385, Pt 3916, Ni 618, Ni 672, and
Cu 426. In RTD and resistance modes the module will inject a constant
current through the RTD or resistor, measure the voltage across the
resistance, and convert to a linearized temperature or resistance reading.
RTD and resistance input types support 2, 3, or 4-wire resistance
measurements.
When configured for current or voltage type inputs, the module converts
the analog values directly into digital counts.
