Allen-Bradley 1734-TB POINT I/O Screw-Clamp Terminal Base Assembly

Product Overview

The Allen-Bradley 1734-TB provides the essential mounting and wiring infrastructure for the POINT I/O system. This terminal base assembly comprises the 1734-MB mounting base and the 1734-RTB removable terminal block, forming a complete unit that supports secure module installation and field-side wiring. It establishes the backplane connection for signal and power distribution across the I/O rack. We supply this unit as 100% Brand New and original, ensuring optimal contact integrity for your distributed I/O architecture.

Technical Specifications

The 1734-TB utilizes a robust open-style design optimized for standard industrial enclosures:

Engineering Advantages

The 1734-TB solves critical wiring and maintenance challenges in high-density automation environments:

• Simplified Maintenance (RTB Design): The removable terminal block allows technicians to replace I/O modules without disconnecting individual field wires. This feature eliminates wiring errors and drastically reduces Mean Time to Repair (MTTR).

• Secure Screw-Clamp Termination: The 8-point screw-clamp mechanism ensures high-vibration resistance. It provides a gas-tight connection that prevents signal intermittent faults in harsh industrial settings.

• Rapid System Scaling: The base snaps directly onto standard 35mm DIN rails and interlocks with adjacent bases. This modular "slide-and-lock" mechanism allows for instantaneous expansion of the I/O rack without complex mechanical fasteners.

• Vertical/Horizontal Flexibility: The open-style chassis supports both vertical and horizontal mounting. This flexibility allows engineers to fit POINT I/O racks into shallow junction boxes or narrow cable ducts where space remains at a premium.

FAQs

What is the difference between the 1734-TB and the 1734-TBS?

The 1734-TB utilizes screw-clamp terminals for traditional, high-torque wire retention. The 1734-TBS utilizes spring-clamp terminals for faster, tool-free wiring. Both bases provide the same electrical functionality and backplane connectivity.

Does the 1734-TB include the mounting base?

Yes. The 1734-TB is a complete assembly that includes both the 1734-MB (mounting base) and the 1734-RTB (removable terminal block). You do not need to purchase these components separately.

Is this terminal base compatible with all POINT I/O modules?

The 1734-TB supports most digital and analog POINT I/O modules. However, high-density modules (such as those with more than 8 points) may require a different terminal base configuration. Always check your specific I/O module's wiring requirements.

How do I ensure a Brand New unit?

We guarantee that every 1734-TB unit is 100% Brand New and ships in its original Allen-Bradley factory packaging. We do not sell "new-other" or refurbished bases, ensuring the screw threads and gold-plated backplane pins remain in pristine, unused condition.
