Allen-Bradley 3400-TB Terminal Block PC Board

Allen-Bradley 3400-TB Terminal Block PC Board is a PCB-mounted terminal block that provides a compact interface for terminating field wiring to a printed circuit board. This model, identified by the 3400-TB designation, integrates with control electronics and automation equipment, helping to organize connections in a small footprint. As a PC board terminal block, it offers secure termination points for conductors on a circuit board, simplifying wiring harnesses and reducing panel clutter in industrial environments. Manufactured by Allen-Bradley, the 3400-TB is suited for applications where a dedicated terminal interface is required on or near a control PCB, such as in control panels and machinery assemblies. In short, it functions as the reliable bridge between field wiring and a PCB in automated systems, enabling clean, maintainable wiring within compact control enclosures.
