- 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.

- 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
