Overview Manuals Connections Installation & Wiring Inspection & Testing Application
  • Field termination interface for compatible 1746 servo-control modules
  • Connects drive, encoder, fast I/O, power and emergency-stop wiring
  • Interfaces to the servo module through the documented 1746-HCA cable

1746-HT centralizes field wiring for a compatible Allen-Bradley 1746 servo-control installation.

Correct selection depends on the host module, 1746-HCA cable, drive, motor, encoder, fast I/O, field-power and machine-safety configuration.

Replacement work should preserve exact terminal identification and drawings, followed by electrical, safety and guarded-motion verification before service.

Availability: Rockwell Automation lists 1746-HT as Discontinued with no planned Rockwell Automation replacement; sourcing is confirmed during quotation.

Description
1746-HT is an Allen-Bradley termination panel used with compatible 1746 servo-control modules. It provides the field-wiring interface for drive command and feedback, encoder signals, fast inputs and output, power supplies, and the emergency-stop circuit.

The official servo-module manual shows connection to the controller module through a 1746-HCA cable. The panel is part of a complete motion architecture and must be checked with the installed servo module, drive, encoder, motor, field power, cable, and safety design.

Before replacement, photograph and label every conductor, record the complete panel and cable catalog numbers, verify the wiring drawing revision, inspect shields and grounding, and perform point-to-point and functional safety tests before enabling motion.

Technical notes
1746-HT replacement requires verified host module and 1746-HCA cable, photographed terminal mapping, shield and ground records, safety review, continuity checks, and guarded motion testing.

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.
Does Allen-Bradley 1746-HT store any servo configuration or motion parameters?
No. It is a termination panel used for field wiring and signal connections. Motion configuration, scaling, tuning, and profiles remain in the associated controller, servo module, or drive.
Can Allen-Bradley 1746-HT be selected without identifying the servo module?
No. Confirm the host servo module, interconnect cable, drive, encoder, motor, field power, I/O use, and wiring-drawing revision before ordering.
What should be recorded before moving wiring to a replacement Allen-Bradley 1746-HT?
Capture clear photographs, wire numbers, terminal positions, shield and ground points, jumper positions, cable catalogs, safety-chain details, and drawing references.
Why might the servo module lose feedback after replacing Allen-Bradley 1746-HT?
Check encoder supply, signal pairs, polarity, shield, grounding, connector seating, interconnect cable, terminal continuity, feedback selection, and accidental conductor interchange.
How should emergency-stop wiring connected through Allen-Bradley 1746-HT be handled?
Follow the approved machine safety design and current risk assessment. Never infer a safety function from terminal position or an undocumented legacy circuit.
Can a visibly undamaged Allen-Bradley 1746-HT be reused?
Inspect terminals, connector latches, insulation, contamination, heat damage, corrosion, shield bonds, labeling, and continuity, then prove every circuit before reuse.
What tests are required after replacing Allen-Bradley 1746-HT?
Perform point-to-point continuity, insulation, and grounding checks, then verify feedback, fast I/O, drive commands, emergency stops, limits, faults, recovery, and guarded motion.
