Description

Allen-Bradley 1756-TBE is an extended-depth terminal block housing for ControlLogix I/O removable terminal blocks. It provides additional wiring depth when the standard housing does not accommodate field conductors up to 2.5 mm² or 14 AWG.

The housing is selected with the appropriate ControlLogix I/O module and separately ordered removable terminal block. Rockwell Automation distinguishes 1756-TBE from the 1756-TBES safety extended-depth housing, so the module type, RTB, terminal identification, and wiring arrangement must be verified before installation or replacement.

Information

Overview Manuals Product Applications Compatibility Lifecycle & Replacement

Features:

  • Extended-depth housing for ControlLogix removable terminal blocks
  • Additional wiring clearance for conductors up to 2.5 mm² or 14 AWG
  • Designed for compatible 1756 I/O module and RTB combinations
  • Supports selected screw or spring terminal technologies
  • Distinct from the 1756-TBES safety extended-depth housing
Allen-Bradley 1756-TBE is an extended-depth terminal block housing for ControlLogix I/O removable terminal blocks. It provides additional wiring-arm clearance when the standard housing cannot accommodate larger field conductors.

The housing is an accessory rather than a removable terminal block, and the correct RTB must be selected separately for the installed I/O module. Terminal identification, conductor routing, housing engagement, and the non-safety application must be confirmed before use.

1756-TBE Allen-Bradley: Verify the ControlLogix I/O module, RTB type, conductor size, terminal identification, field-power isolation, and non-safety housing requirement before installation.
Allen-Bradley 1756-TBE ControlLogix Extended-Depth Housing Manuals, Datasheets, Official Documents, Links Important Notice: Official documents are provided through manufacturer sources. Accessories, manuals, cables, certificates and other items are not included unless listed in the stock item description.
  • Providing clearance for 14 AWG ControlLogix field wiring
  • Enclosing removable terminal block field connections
  • Supporting field termination on ControlLogix digital I/O
  • Supporting field termination on ControlLogix analog I/O
  • Maintaining removable wiring-arm access during I/O service
1756-TBE is applied where a compatible non-safety ControlLogix I/O removable terminal block requires more wiring depth than the standard housing provides. Application engineering must confirm the I/O module, RTB type, conductor size, terminal layout, cabinet clearance, and field-power isolation procedure.
1756-TBE is intended for compatible Allen-Bradley ControlLogix 1756 I/O modules and separately selected removable terminal blocks that require an extended-depth housing for conductors up to 2.5 mm² or 14 AWG. Compatibility depends on the exact I/O module and RTB combination. It is not interchangeable with the 1756-TBES safety extended-depth housing.
Rockwell Automation lists 1756-TBE with an Active lifecycle status. Before replacement, record the complete catalog number, I/O module, RTB type, terminal identification, conductor size, and wiring position. De-energize field power where required and confirm that the replacement is the standard non-safety 1756-TBE housing, not 1756-TBES, before reinstalling the RTB and restoring power.

Technical notes

Use 1756-TBE only with a documented non-safety ControlLogix I/O module and the correct removable terminal block. De-energize field power where required, preserve terminal identification, verify 2.5 mm² or 14 AWG conductor routing, and reinstall the housing and RTB securely before restoring power.

FAQs

  • What is the purpose of 1756-TBE?

    +
    It provides additional terminal-block wiring depth for compatible ControlLogix I/O removable terminal blocks.
  • When is the extended-depth housing required?

    +
    Rockwell Automation specifies it when the standard housing does not accommodate conductors up to 2.5 mm² or 14 AWG.
  • Is a removable terminal block included with 1756-TBE?

    +
    No. The compatible RTB is selected and ordered separately for the ControlLogix I/O module.
  • Can 1756-TBE replace 1756-TBES?

    +
    No. 1756-TBES is the safety extended-depth housing and is not interchangeable with the standard 1756-TBE.
  • What must be checked before installation?

    +
    Confirm the I/O module, RTB type, terminal identification, conductor size, field-power isolation, and secure housing engagement.
