The NI FP-TB-1 FieldPoint Terminal Base is a DIN rail-mounted termination module that serves as the interface between FieldPoint I/O modules and field wiring in distributed industrial control systems. It accommodates single 8 or 16-channel I/O modules, establishes the local communication and power bus, and provides 36 screw terminals for field connections. The FP-TB-1 is a general-purpose terminal base compatible with most FieldPoint I/O module types and can coexist with FP-TB-2 units on the same FieldPoint bank.

– Compatibility & Integration
The FP-TB-1 connects with all FieldPoint I/O modules except dual-channel series types. It shares DIN rail installations and FieldPoint banks with FP-TB-2 terminal bases without restriction. FieldPoint I/O modules typically draw power through the local bus from network modules, eliminating external power supply requirements in most configurations.
