Allen-Bradley 1734-TBS Terminal Base Assembly

The Allen-Bradley 1734-TBS Terminal Base Assembly is a two-piece POINT I/O wiring base that pairs a mounting base (1734-MB) with a removable terminal block (1734-RTBS). It provides eight spring-clamp terminals for field wiring and is designed for DIN-rail mounting in 35 mm rail systems, per EN50022 specifications, to support compact, modular installations. The 1734-TBS configuration (1734-MB plus 1734-RTBS) serves as the base for POINT I/O modules that use spring-clamp termination, allowing eight conductors to be terminated in a single base and enabling easy replacement of the RTB without disturbing the mounting base. This wiring base assembly is used to connect field devices to 1734 POINT I/O modules in industrial control panels, delivering a structured, removable terminal solution that simplifies wiring and maintenance in DIN rail enclosures.
