One-Piece Screw-Clamp Base | 1734-TOP | Allen-Bradley

Allen-Bradley 1734-TOP POINT I/O One-Piece 8-Position Screw-Clamp Terminal Base

Product Description

The Allen-Bradley 1734-TOP (Catalog Number: 1734-TOP) is a high-reliability one-piece terminal base module specifically engineered for the POINT I/O 1734 platform. It functions as the critical physical and electrical link between the backplane communication bus (PointBus) and the field-side wiring. Designed for durability in industrial environments, the 1734-TOP features an 8-position screw-clamp interface that ensures secure, vibration-resistant terminations for digital and analog signals.

A key technical distinction of the 1734-TOP is its integrated one-piece construction. Unlike two-piece assemblies (base plus separate removable terminal block), this unit combines the mounting base and the terminal block into a single robust component. This design is optimized for high-vibration applications where a secure mechanical connection is paramount. It also incorporates a mechanical keyswitch, which is user-configurable to match the specific I/O module being inserted, effectively preventing electrical mismatches during installation or hot-swapping procedures.

Technical Specifications

Detailed engineering parameters for the 1734-TOP:

Key Features

• One-Piece Integrity: Integrated housing provides superior mechanical support and resistance to loosening under high-frequency vibration.

• Standardized 8-Point Terminal: Compatible with a vast array of digital and analog POINT I/O modules requiring standard terminations.

• Mechanical Safety Keying: Adjustable dial ensures that only the correct module type can be inserted into the base, preventing hardware damage.

• Modular Space Saving: Compact 12mm width allows for high-density I/O configurations in restricted control cabinet spaces.

• Direct Field Termination: High-quality screw clamps facilitate direct connection of copper wiring ranging from 22 to 14 AWG.

Industrial Application Scenarios

• Vibration-Prone Machinery: Ideal for on-machine mounting or locations subject to constant mechanical oscillation.

• High-Density Control Panels: Used in modular packaging and sorting systems where DIN rail space is at a premium.

• Distributed I/O Networks: Facilitates remote signal acquisition via EtherNet/IP, DeviceNet, or ControlNet adapters.

• OEM Skid Manufacturing: Provides a standardized, cost-effective wiring solution for small-to-medium scale machine assemblies.
