-
Yes. The 3WHB10K is required to measure three-wire temperature probes on the AM16/32B. As both RTDs and thermistors can be measured on the 3WHB10K, refer to the AM16/32B Relay Multiplexer Instruction Manual for the proper programming.
-
The 4WPB100, 4WPB1K, and 4WHB10K terminal input modules can be used instead of the 3WHB10K module. However, ensure that the jumper is installed between the ground side of the sensor and the low input of the second channel to maintain the four-wire accuracy.
-
Yes. The CR1000 can measure eight PT100 sensors with a 3WHB10K terminal input module. The measurement instructions, however, have to reflect that more than one sensor is being excited with the same excitation channel (MeasPEx argument) in the BrHalf() or BrHalf3W() instruction.

Multiplexers
The AM16/32-series and AM25T multiplexers are compatible with the 3WHB10K.
Data Logger Considerations
The 3WHB10K uses two adjacent single-ended analog inputs; an adjacent analog ground channel accepts the "ground prong" of the 3WHB10K. Not all data logger terminal strips have this sequence on all channels, so please check your data logger's wiring panel to confirm channel assignments, especially if you plan to use multiple terminal input modules.
Newer CR10X Wiring Panels can accommodate both the 3WHB10K and the cover associated with the CR10XTCR (reference thermistor for thermocouple measurements). Specifically, the physical configuration of the thermocouple cover, the data logger input terminals, and the terminal input modules allow sufficient room for the cover to be used with a Terminal Input Module attached. In contrast, older CR10TCRs are not deep enough.
