Allen-Bradley 1734-RTB Terminal Base Assembly

The Allen-Bradley 1734-RTB Terminal Base Assembly provides a DIN-rail mounted mounting base and removable terminal block for POINT I/O modules, delivering an integrated platform and field-wiring interface for distributed I/O systems. It combines the 1734-MB mounting base with the 1734-RTB removable terminal block, securing the I/O module to the DIN rail and enabling POINTBus backplane connectivity while simplifying field wiring and module replacement. The 8 IEC screw-clamp terminals in an open-style construction support POINT I/O digital, analog, and specialty modules and facilitate reliable field device wiring and maintenance. This assembly is widely used in manufacturing equipment, process control applications, packaging machinery, and material handling systems within distributed automation setups, and is designed for OEM replacement, maintenance, retrofit, and expansion projects. Common replacements include 1734-TB and 1734-RTBS variants, and the system is part of the Bulletin 1734 POINT I/O family.
