Allen-Bradley 1734-MB Terminal Base Module Assembly

Allen-Bradley 1734-MB Terminal Base Module Assembly is a two-piece POINT I/O terminal base that combines the mounting base (1734-MB) with a removable eight-terminal spring-clamp terminal block (1734-RTBS) to form the 1734-TBS base. This assembly provides eight field-wiring connections that line up with POINT I/O modules in the 1734 family, enabling secure spring-clamp terminations for eight conductors used by digital and analog I/O modules. The mounting base is designed for DIN-rail installation in industrial cabinets, and the RTBS attaches to the base to simplify wiring changes and maintenance. The 1734-RTBS is an eight-terminal spring-clamp RTB, delivering reliable, low-impedance terminations for typical automation wiring applications. Use this terminal base assembly when wiring eight conductors to a POINT I/O module in Rockwell Automation’s 1734 series, recognizing that other RTB variants (such as screw-clamp versions) exist for different wiring preferences and installation needs. This configuration is common in compact control panels and machine-level controls where eight-channel field wiring must be routed efficiently to a POINT I/O module.
