More Information

Overview Manuals RTB Matching Wire Routing Panel Clearance Application
  • Use 1756-TBE when a ControlLogix RTB installation needs additional wire-routing space
  • Select the actual RTB from the I/O module requirements; it is not included with the housing
  • Verify enclosure depth and keep the standard 1756-TBE distinct from safety housing 1756-TBES

1756-TBE is an Allen-Bradley ControlLogix extended-depth terminal-block housing.

It increases available wire-routing capacity to 628 mm² for installations using heavy-gauge conductors while leaving RTB selection dependent on the I/O module.

Check RTB fit, conductor routing, strain relief and cabinet depth before closing the enclosure.

Availability, condition, price, and shipping time for 1756-TBE are confirmed during quotation.

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.

  • Select the RTB required by the specific ControlLogix I/O module
  • Keep screw-clamp and spring-clamp RTB identities distinct
  • Order the RTB separately because 1756-TBE is the housing only
  • Use the 628 mm² routing capacity without defeating conductor bend radius
  • Keep conductors inside the strain-relief area and housing grooves
  • Verify that heavy-gauge insulation and conductor count allow the housing to latch
  • Allow for the documented 157.43 mm module-to-chassis depth
  • Check wire duct and cabinet-door interference before installation
  • Do not substitute the 1756-TBES safety housing for standard I/O
  • ControlLogix analog I/O terminations using 14 AWG conductors
  • ControlLogix digital I/O panels needing additional wire-routing volume
  • ControlLogix RTB installations using heavy-gauge plant wiring
Description
1756-TBE is an Allen-Bradley ControlLogix extended-depth terminal-block housing for removable terminal block installations.

Rockwell Automation specifies it when additional wire-routing space is required, including heavy-gauge wiring. It provides 628 mm² wire capacity and is a housing only; the I/O module and the module-specific RTB are separate items.

Use the RTB required by the installed I/O module, maintain conductor bend radius and strain relief, and verify the added enclosure depth before closing the panel.

Technical notes
1756-TBE is the standard ControlLogix extended-depth RTB housing and provides additional wire-routing capacity. The module-specific RTB, I/O module and safety housing 1756-TBES are separate identities.

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 information should be provided when ordering 1756-TBE?
Provide the complete ControlLogix I/O module catalog number, required RTB catalog number, clamp style, conductor size and enclosure-clearance limits. The 1756-TBE is only the extended-depth housing, so the compatible RTB must be selected separately.
When should 1756-TBE be chosen instead of the standard RTB housing?
Use it when the installed conductors need more routing volume or bend space, especially with heavy-gauge wiring. It increases wire capacity but also increases the overall module depth.
Can 1756-TBE be used in place of the 1756-TBES safety housing?
No. Rockwell Automation distinguishes the standard 1756-TBE from the 1756-TBES safety housing. Follow the safety-module documentation and do not mix safety and nonsafety housing identities.
Does 1756-TBE make an incompatible RTB fit an I/O module?
No. The I/O module determines the required RTB pin count and clamp style. The extended housing adds wiring space but does not change the module-to-RTB electrical interface.
Why might a cabinet door no longer close after fitting 1756-TBE?
The extended housing increases the documented module-to-chassis depth. Check enclosure clearance, wire bend radius, duct position and door-mounted equipment before installation.
Why can the 1756-TBE cover fail to latch after wiring?
Look for conductors outside the strain-relief area, excessive insulation diameter, tight bend radius, overfilled routing space or an RTB that is not fully seated in the housing grooves.
Can a used 1756-TBE be reused on another ControlLogix module?
Only after confirming the new module’s correct RTB and inspecting the housing grooves, latch and strain-relief features. A cracked or heat-damaged housing should not be reused.
