Introduction to the 1734-RTB Removable Terminal Block
The Allen-Bradley 1734-RTB is a fundamental component of the POINT I/O™ system, serving as a removable terminal block with a screw-clamp mechanism. This component is designed to provide the physical connection point for field wiring to individual I/O modules. Its «removable» nature is a key feature for industrial maintenance, allowing technicians to replace faulty I/O modules without the need to disconnect and rewire every single field lead, thus significantly reducing machine downtime.
Technical Features and Design
The 1734-RTB is engineered to snap securely onto a 1734-TB or 1734-TB3 wiring base. It features 8 terminal points, each capable of handling a variety of wire sizes. The screw-clamp design provides a high-torque, gas-tight connection that is ideal for standard industrial environments where heavy-gauge wiring or ferrules are used. The housing is made of high-quality industrial-grade plastic, rated for the same temperature ranges as the POINT I/O modules themselves.
Key Technical Specifications
- Connection Type: Screw-clamp terminals.

Operational Benefits
By utilizing the 1734-RTB, panel builders can pre-wire the terminal blocks before the actual electronics are installed. During commissioning or repair, the terminal block can be unplugged from the base, keeping the field wiring intact. This modularity is a hallmark of the Rockwell Automation hardware ecosystem, ensuring that complex automation racks remain manageable and serviceable over long lifecycles.

Frequently Asked Questions
Can I use the 1734-RTB on a spring-clamp base? Yes, the RTB is the removable portion and can be interchanged if the mounting base supports it, though usually, screw and spring types are kept consistent across a rack.
