- Interfaces IMC 123 axis control with dedicated feedback and drive wiring
- Uses the documented 1771-CAE cable and compatible axis termination panel
- Requires feedback polarity, shielding and axis wiring to be preserved during service
1771-HS3A is an Allen-Bradley IMC 123 motion-control module for a 1771 I/O chassis.
Its axis connection depends on the specified 1771-CAE cable, termination hardware and differential feedback signals rather than general-purpose 1771 field wiring.
Before exchanging the module, identify the installed termination panel and record feedback polarity, shield connections, drive commands and machine-direction conventions.
Availability, condition, price, and shipping time for 1771-HS3A are confirmed during quotation.

- Encoder feedback is carried through differential AX, BX, and ZX signal pairs
- Feedback and drive conductors use dedicated returns, grounds, and shields
- Preserve the installed axis assignments before disconnecting the module
- The 1771-CAE cable links the module to the documented axis termination panel
- Both cable ends use 26-pin subminiature D connector hardware
- Inspect connector pins, cable shielding, and strain relief before reuse
- Confirm remote-I/O adapter compatibility before installing the module
- Match the termination-panel catalog number and cable orientation
- Restore the verified IMC 123 application configuration before axis commissioning
- IMC 123 multi-axis machine control
- Legacy encoder and drive-feedback termination
- Maintenance replacement in documented 1771 motion systems
