Overview
The Allen-Bradley 1734-TOP is a terminal base assembly from Rockwell Automation’s POINT I/O platform. Each 1734-TOP unit serves as both the mechanical mounting bracket and electrical wiring interface for a single POINT I/O module. The 1734-TOP is a POINT I/O one-piece terminal base featuring an integrated 8-position screw-clamp wiring block that provides the mounting and wiring interface for POINT I/O modules while distributing both field power and backplane communication. This lot contains 5 units, ideal for building multi-module distributed I/O systems.
Key Features
- 8 screw clamp terminals with open-style DIN mounting design
- One-piece design for ease of installation
- Mechanical keying prevents incorrect module placement, improving installation accuracy and reducing downtime
- Removable terminal block (RTB) for easy maintenance and supports removal and insertion under power (RIUP)
- Designed for compatibility with various POINT I/O modules, enhancing versatility in modular setups
- Compact design allows high-density installations on DIN rails

- Mounting: DIN Rail (35 mm standard)
- Terminal Type: Screw-clamp (removable terminal block)
Typical Applications
- Distributed I/O systems requiring modular, scalable architecture
- Factory automation controls with digital, analog, relay, and specialty POINT I/O modules
- Machine control and equipment integration in manufacturing environments
- Panel-mounted control systems using DIN-rail enclosures
- Applications requiring hot-swappable module replacement without powering down
