Allen-Bradley 1444-TB-A Dynamix 1444 Terminal Base

Product Overview

The Allen-Bradley 1444-TB-A functions as the essential wiring and mounting foundation for the Dynamix 1444 integrated machinery protection system. This terminal base provides the mechanical and electrical interface required for the 1444-DYN04-01RA dynamic measurement module. It facilitates all field sensor connections, power distribution, and relay wiring in a high-density format. We supply this unit as 100% Brand New and Factory Original, ensuring optimal signal integrity for your critical vibration, temperature, and tachometer monitoring applications.

Technical Specifications

The 1444-TB-A utilizes high-performance materials to maintain stable connections across demanding industrial environments:

Engineering Advantages

• Optimized Thermal Performance: The 1444-TB-A supports an extended operating temperature range from -25°C to +70°C. This allows installation in decentralized cabinets located near heavy machinery, where ambient temperatures often fluctuate beyond the limits of standard office-grade hardware.

• Facilitates Hot Swapping: The terminal base design permits the removal and insertion of the 1444-DYN04-01RA measurement module without disturbing the field wiring. This minimizes machinery downtime during maintenance cycles or hardware upgrades by keeping the signal trunk intact.

• High-Density Wiring Solution: The base architecture organizes complex sensor inputs and relay outputs into a manageable footprint. This solves the challenge of narrow space constraints in crowded control panels while maintaining clear separation between power and signal leads.

• Enhanced Signal Protection: By utilizing the required 1444-TBA-RPC connector sets, the base ensures secure, low-resistance terminations. This protects low-voltage vibration signals from attenuation and electromagnetic interference, which is critical for accurate machinery protection and diagnostics.

• Simplified DC Integration: The unit handles up to 5 Amps and operates within a standard 24V DC (18-32V range) industrial power environment. It streamlines the power bus architecture by utilizing a single SELV/Class 2 source for both the base and the mated module.

FAQs

• Is this 1444-TB-A unit 100% Brand New?

  Yes. We guarantee this terminal base is 100% Brand New, arriving in its original Allen-Bradley factory packaging. We never supply used or refurbished bases, as mechanical contact wear can compromise sensitive measurement data.

• Does the 1444-TB-A include the removable connectors?

  No. This part number refers to the terminal base itself. To complete the installation, you must order the 1444-TBA-RPC connector set separately, which provides the removable plugs for your field wiring.

• Can I use this base with any Dynamix module?

  This specific terminal base, "Type A," supports the 1444-DYN04-01RA measurement module. Always verify the module keying and part number to ensure compatibility before applying power.

• What type of power supply should I use with the 1444-TB-A?

  You must use a SELV (Safety Extra Low Voltage) or Class 2 rated power supply. Using the correct power source protects the sensitive electronics in the mated measurement module from voltage spikes and ensures compliance with industrial safety standards.
