Overview of the 1734-RTBS Spring-Clamp Block
The Allen-Bradley 1734-RTBS is the spring-clamp version of the removable terminal block for the POINT I/O™ modular platform. This component provides an alternative to traditional screw terminals, utilizing constant-tension spring technology to hold field wires in place. It is particularly valued in high-vibration applications where mechanical screws might loosen over time, ensuring a maintenance-free electrical connection throughout the equipment’s lifespan.
Advanced Connectivity and Speed
The spring-clamp mechanism of the 1734-RTBS allows for significantly faster wiring during the initial cabinet build. By using a small screwdriver to open the clamp, the wire is inserted and then automatically gripped with the correct pressure upon release. This eliminates the need for manual torque checking. Like its screw-clamp counterpart, the 1734-RTBS is fully removable, preserving the field wiring during module swaps.

Why Choose Spring-Clamp?
In modern industrial automation, reducing labor costs is critical. The 1734-RTBS allows for «tool-less» maintenance once installed. It is highly resistant to thermal expansion and contraction, making it the preferred choice for environments with fluctuating temperatures. Its compact footprint maintains the 12mm width of the POINT I/O system, allowing for dense I/O configurations without the risk of wire fatigue.

Maintenance Insights
When replacing a module, simply depress the latches to pull the 1734-RTBS block away from the base. The wiring remains organized and labeled, preventing cross-wiring errors when the new module is installed. This enhances the overall safety and reliability of the control system.
