Overview Manuals XM Module Fit Wiring & DeviceNet Lifecycle Planning Applications

Features:

  • Screw-clamp E base documented for XM-360, XM-361 and XM-362 modules.
  • DeviceNet interface in the XM monitoring-system terminal-base family.
  • OEM lifecycle: discontinued with no planned Rockwell replacement.
1440-TB-E is the XM-944 terminal-base position named for the three process and temperature measurement modules.

Its DeviceNet interface makes the terminal wiring and neighboring XM arrangement part of a service review.

Rockwell discontinued 1440-TB-E at the end of 2016, so an installed system needs an exact-base sourcing or redesign decision rather than an assumed letter substitution.

Apter Power can help review documentation, quotation and sourcing for the Allen-Bradley 1440-TB-E Screw Clamp E Terminal Base.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Rockwell identifies 1440-TB-E as the XM-944 base for XM-360, XM-361 and XM-362 modules.
  • The XM-360 user guide requires the XM-944 terminal base and specifies its keyswitch position; do not move the keyswitch after wiring.
  • Confirm the installed module catalog before replacing an E base, since other XM terminal-base letters serve other module types.
  • 1440-TB-E uses screw-clamp termination in a DeviceNet-linked XM installation.
  • Record each process or temperature signal conductor and the adjacent-base order before removing the wired base.
  • Follow the applicable XM-360/361/362 module manual for terminal assignment and power handling rather than matching terminals by appearance.
  • Rockwell lists 1440-TB-E as discontinued from December 31, 2016.
  • The official product record states that no Rockwell replacement is planned for this terminal base.
  • For an installed XM system, compare exact E-base stock, module type and wiring record before deciding between repair and a wider migration.
  • Terminal base for an XM-360 process measurement module.
  • Terminal base for an XM-361 universal temperature measurement module.
  • Terminal base for an XM-362 isolated temperature measurement module in a retained legacy XM system.
Description
1440-TB-E is an Allen-Bradley screw-clamp E terminal base associated with XM-360, XM-361 and XM-362 measurement modules. Rockwell documentation identifies this base as the XM-944 position in the XM terminal-base family.

The 1440-TB-E is part of a DeviceNet-connected XM installation, so its terminal wiring and position in the adjacent-base chain affect the installed monitoring arrangement. It is not the same terminal-base selection as the B type used for other XM modules.

Rockwell Automation discontinued 1440-TB-E on December 31, 2016 and lists no planned Rockwell replacement. For a legacy repair, document the exact XM module, base label and wiring before sourcing, and do not assume a different terminal-base letter is interchangeable.

Technical notes
The Allen Bradley 1440-TB-E utilizes a robust 52-terminal screw-clamp interface divided across an organized three-tier block structure to streamline field signal routing. Featuring an integrated mechanical keyswitch and supporting independent instrument extraction under live plant power, the Allen Bradley 1440-TB-E guarantees zero field wire disruption during component maintenance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must be confirmed before selecting 1440-TB-E?
Confirm the complete 1440-TB-E catalog number, the installed screw clamp e terminal base, and the host-equipment context. It is a legacy DeviceNet XM terminal-base variant. A shortened family reference or similar appearance is not sufficient for an exact replacement.
How should 1440-TB-E be used in an installed system?
1440-TB-E should be used only within the documented configuration of the installed Rockwell Automation system. Compare the removed unit, wiring or connector position, and the relevant system record before commissioning.
What documentation is useful for 1440-TB-E service?
Use the exact 1440-TB-E catalog number to obtain the relevant Rockwell Automation product and installation documentation. Keep the removed-unit nameplate, revision evidence, and host model with the service record.
What should be checked before installing 1440-TB-E?
Follow site-approved isolation procedures, then verify connectors, terminal positions, mounting arrangement, and the applicable system configuration. Installation requirements depend on the actual host equipment and not on the model name alone.
What information should accompany a sourcing request for 1440-TB-E?
Provide the full 1440-TB-E catalog number, clear nameplate photographs, any visible revision or assembly marking, the host-equipment model, quantity, destination, and requested date. These details allow an exact review rather than a family-level quote.
How does lifecycle status affect 1440-TB-E planning?
1440-TB-E is recorded as Discontinued / Obsolete by OEM. Preserve the installed-system evidence and confirm the exact required configuration before arranging a replacement or maintenance purchase.
