Information About 1734-TOP

The 1734-TOP is a core component of Rockwell Automation’s POINT I/O platform, serving as both the mounting base and field-wiring interface for POINT I/O modules. Its one-piece screw-clamp design ensures secure electrical connections while simplifying installation and maintenance. This terminal base supports eight wiring positions, enabling connectivity for digital, analog, relay, and specialty POINT I/O modules. Mechanical keying prevents incorrect module placement, improving installation accuracy and reducing downtime. The 1734-TOP mounts directly onto a DIN rail—either horizontally or vertically—and automatically engages with adjacent POINT I/O modules, completing the backplane and power bus connections without additional tools. Built for industrial environments, the terminal base supports up to 300V supply, 8A terminal current, and accommodates 22–14 AWG (0.25–2.5 mm²) wire sizes. Reliable grounding is achieved through the DIN rail, ensuring proper system integrity in distributed I/O applications.

Key Features:

  • One-piece POINT I/O terminal base
  • Integrated 8-position screw-clamp wiring block
  • Provides backplane communication & field-power distribution
  • Mechanical keying prevents incorrect module installation
  • Tool-less assembly between adjacent POINT I/O modules
  • DIN-rail mountable (vertical or horizontal)
  • Supports up to 300V and 8A
  • Compatible with a wide variety of POINT I/O modules
  • Compact, modular design for easy panel configuration

Compatible with a wide range of POINT I/O modules—including digital input/output, analog input/output, counters, and relay modules—the 1734-TOP provides a flexible and scalable wiring platform for modern control architectures.

 

Frequently Asked Questions about 1734-TOP
Question: What is the purpose of the 1734-TOP?
Date Update:13/06/2025
Answer:

The 1734-TOP is a terminal base unit used in Allen-Bradley's POINT I/O systems. Its primary function is to provide a mechanical and electrical connection between I/O modules and field wiring. It contains screw terminals for secure wire attachment and ensures proper alignment with the backplane. The terminal base also distributes power and communication between modules. It simplifies modular I/O installation and supports hot-swappable module changes.

Question: What are the module’s dimensions and weight?
Date Update:13/06/2025
Answer:

The 1734-TOP measures approximately 49 x 12 x 144 mm (1.93 x 0.47 x 5.67 inches). It weighs about 63.8 grams (2.25 ounces). This compact design allows high-density installations on DIN rails. Despite its small size, it houses robust terminal connections and mechanical locks. It contributes to a modular, space-saving control system layout.

Question: Is mechanical keying available?
Date Update:13/06/2025
Answer:

Yes, the 1734-TOP includes mechanical keying features to prevent incorrect I/O module installation. Each base has a designated keying position for specific module types. This prevents operator errors during installation or maintenance. The keying is color-coded (orange) for visibility. It enhances system safety and reliability.

Question: What is the maximum terminal current and voltage?
Date Update:13/06/2025
Answer:

The terminals can handle up to 8 A of current. The maximum terminal voltage is 300V. These values are sufficient for most control-level signals and power distribution tasks. Ensure that wiring and connected modules do not exceed these ratings. Overloads may lead to improper operation or damage.

Question: Is the module still in production?
Date Update:13/06/2025
Answer:

Yes, the 1734-TOP is still being actively manufactured by Rockwell Automation. It is a standard part of the POINT I/O product line. Its availability ensures compatibility with modern systems and support for legacy installations. Replacement parts and accessories are widely available. It remains a reliable solution for industrial I/O configurations.
