The NI FP-AI Series dual-channel analog input modules have either two single-ended or one differential input. The NI FP-TC Series are 2-channel input modules for either J or K type thermocouples. The NI FP-RTD Series have two 2, 3, or 4-wire RTD inputs. You can install up to six dual-channel modules on a single FP-TB-10 dual-channel terminal base. Dual-channel modules can coexist with 8 and 16-channel FieldPoint modules in the same FieldPoint bank. 2, 3, and 4-wire RTD modules Isolated, module-to-module, 2,500 Vrms V, mV, A, and mA modules; 2 single-ended inputs or 1 differential J and K thermocouple modules
