1734-TB POINT I/O Terminal Base 8-Position Screw Clamp | Allen-Bradley

The Original New Allen-Bradley 1734-TB POINT I/O Terminal Base is a two-piece wiring base assembly designed for the 1734 POINT I/O distributed I/O system. It provides the physical mounting and electrical interface between POINT I/O modules and field wiring. The 1734-TB features 8 screw-clamp terminations and consists of a 1734-MB mounting base and a 1734-RTB removable terminal block (RTB), enabling pre-wiring and quick module replacement without rewiring. This terminal base is the standard field wiring interface for 8‑point POINT I/O modules, providing reliable connections for digital, analog, and specialty I/O modules.
