Allen-Bradley 1734-MB Digital Input Output Module

Allen-Bradley 1734-MB is the mounting base for POINT I/O digital input/output modules, designed for DIN-rail installation in a POINT I/O configuration. It provides the mechanical foundation and electrical interface for 1734 POINT I/O modules and is intended to be used with the removable terminal block 1734-RTB or 1734-RTBS, which handles the field wiring for the I/O channels. In a typical setup, the 1734-MB mounts to a DIN rail, and the 1734-RTB/RTBS attaches to the base to connect wiring to individual 1734 I/O modules that plug into the mounting base and join the POINT I/O bus. This base assembly supports a compact, modular I/O rack that enables scalable expansion with additional 1734 digital I/O modules while keeping wiring organized and accessible for maintenance or replacement. As part of the Allen-Bradley POINT I/O family, the 1734-MB is essential for creating a DIN-rail mounted I/O backbone and works alongside 1734 RTB terminal blocks to provide a reliable field wiring interface for distributed automation applications.
