Allen Bradley 1440-TB-B XM Dynamic Measurement Terminal Base

Product Overview

The Allen Bradley 1440-TB-B serves as the essential mounting and wiring interface for the XM series of intelligent dynamic measurement modules. Specifically engineered to house the XM-320 and XM-220 vibration and position monitoring modules, this terminal base facilitates all field wiring through a rugged screw clamp termination system. It provides the mechanical foundation and electrical backplane for distributed power and communication within an XM monitoring system. We supply this unit as 100% Brand New and Factory Original, ensuring maximum contact integrity for your critical machinery protection circuits.

Technical Specifications

The 1440-TB-B utilizes industrial-grade materials to ensure stable signal transmission in high-vibration environments:

Engineering Advantages

• Secure Screw Clamp Termination: The 1440-TB-B utilizes high-torque screw clamps to secure field wiring. This design prevents wire pull-out and maintains low-resistance connections in high-vibration zones typical of pump and turbine monitoring applications.

• Modular "Hot Swap" Capability: The terminal base allows for the removal and replacement of XM-320 or XM-220 modules without disturbing the field wiring. This significantly reduces downtime during maintenance or module upgrades by keeping the signal path intact.

• Optimized Thermal Stability: The hardware operates reliably across a 20°C to 65°C range. The housing design promotes natural convection, preventing heat buildup at the terminal interface even when multiple modules operate in dense configurations.

• Simplified Power Distribution: The base manages internal power distribution (21.6 to 26.4 VDC) across the XM system. It eliminates redundant external wiring by bridging power between adjacent terminal bases, streamlining the control panel layout.

• Rapid DIN Rail Integration: The integrated locking mechanism snaps onto standard 35mm DIN rails. This permits fast installation in narrow control cabinets while providing the mechanical rigidity required to support precision measurement electronics.

FAQs

• Is this 1440-TB-B unit 100% Brand New?

  Yes. We guarantee this terminal base is 100% Brand New and arrives in its original factory packaging. We do not supply refurbished or used surplus bases, as pristine screw threads and clean contact surfaces are critical for accurate measurement signals.

• Can I use the 1440-TB-B with an XM-120 module?

  No. This specific base is optimized for the XM-320 (Position) and XM-220 (Dual Speed) modules. Always verify your module part number before installation to ensure electrical and mechanical compatibility.

• What is the recommended torque for the screw clamps?

  Follow the standard Allen Bradley torque specifications listed in the XM series installation manual. Proper torque ensures the wire remains secure under vibration without shearing the copper conductor.

• Does this base include the XM module itself?

  No. The 1440-TB-B is the terminal base only. You must purchase the XM-320 or XM-220 module separately to complete the measurement node.
