Description
The product detailed in this specification is part number 186421B-01, categorized under FieldPoint. Specifically, it is the model FP-TB-3, a National Instruments FP-TB-3 FieldPoint Isothermal Terminal Base designed and manufactured by National Instruments. For ordering purposes, the part number is 777519-03.
This particular model boasts 18 screw terminals, with 16 of these terminals numbered and 2 dedicated C channel terminals. It supports a maximum total current of 10 A across the V and C terminals. When considering the current draw, users are advised to use one terminal for the return path if the current draw is less than 3 A; for current draws greater than 3 A, the individual C terminals should be utilized.
The FP-TB-3 is designed for use with the FP-TC-120 module but is also compatible with thermocouple modules and I/O modules that do not require external power using terminals 1 to 16. Its construction is isothermal, a feature that minimizes thermal gradients on the I/O terminals. This design choice enhances measurement preciseness by ensuring a uniform temperature distribution across the terminal base, which is critical for accurate sensor readings and data collection.
