Description
The FP-TB-3 Isothermal Terminal Base, part number 777519-03, falls under the FieldPoint category and is designed by National Instruments. This terminal base is not recommended for new designs but serves specific existing setups with its unique features.
It comes equipped with 18 Screw Terminals, which includes 16 numbered terminals and 2 dedicated C channel terminals. This configuration supports a maximum total current of 10 A through V and C terminals. The FP-TB-3 is compatible with the FP-TC-120 module and other I/O modules that do not require external power.
For current draw considerations, it is advised to use one terminal for the return path if the current draw is less than 3 A. However, if the current draw exceeds 3 A, it is recommended to use individual C terminals. This ensures the safety and efficiency of the power distribution within the system.
The construction of the FP-TB-3 is isothermal to minimize thermal gradients, enhancing the reliability and performance of the terminal base. In terms of thermal gradient evaluation, it is suggested to divide the higher amount of heat dissipated by each adjacent module by 11 W/°F to ensure optimal operation.
This comprehensive design and construction make the FP-TB-3 a specialized solution for certain FieldPoint applications, adhering to the stringent quality standards of National Instruments.
