Description
Allen-Bradley 1734-TB POINT I/O Terminal Base
Configured for wiring termination and backplane connectivity in POINT I/O systems, the Allen-Bradley 1734-TB (1734-TB Terminal Base) provides direct electrical execution. The terminal base accepts removable IEC screw-clamp terminations and interfaces field wiring with compatible POINT I/O modules through the POINTBus backplane architecture.

EtherNet/IP and I/O Density Scaling Considerations
Within POINT I/O architectures, the 1734-TB serves as the physical termination interface between field conductors and installed I/O electronics. The terminal base does not execute application logic or network protocol processing; instead, it provides the mechanical and electrical connection path required for modular I/O density scaling. Proper terminal-base selection must match the installed POINT I/O module type to maintain backplane continuity and field wiring integrity.
Frequently Asked Questions
Q: Does the 1734-TB support hot replacement of field wiring assemblies?
A: The terminal block is removable, allowing field wiring to remain terminated while a compatible POINT I/O module is removed or replaced. Follow system-specific maintenance procedures before performing module replacement.
Q: What backplane load does the terminal base place on the POINTBus?
A: The specified maximum POINTBus current requirement is 75 mA.
Q: What conductor types can be terminated on the 1734-TB?
A: The terminal base supports shielded copper conductors, either solid or stranded, from 0.25 mm2 to 2.5 mm2 (23-13 AWG).
Field Installation Guidelines
-
Mount the terminal base on a properly grounded DIN rail before installing the associated I/O module.
-
Verify that field power wiring remains within the specified 10-28.8 VDC range.
-
Use shielded copper conductors and terminate cable shields according to plant grounding practices.
-
Separate low-level signal wiring from high-current power conductors to reduce conducted noise.
-
Tighten screw-clamp terminals according to manufacturer installation procedures.
-
Confirm terminal assignment before energizing the field circuit.
-
Inspect the removable terminal assembly for secure engagement with the installed POINT I/O module.
-
Maintain adequate clearance around the assembly to support heat dissipation and service access.
