- Trace the installed RJ11 lead to the DH-485 link coupler before removal
- Record the adjacent coupler, cable catalog numbers, supply wiring, and target SLC processor
- Do not assume interchangeability from connector appearance or the sample diagram alone
1747-AICR replacement planning should begin with the installed communication path rather than connector appearance alone.
Rockwell's sample diagram places this catalog number on the RJ11 side of an SLC-to-DH-485 link-coupler arrangement alongside programming and hand-held terminal connections.
Because the diagram does not provide a standalone specification table or interchangeability statement, verify the complete nameplate, pinout, mating coupler, cable set, supply wiring, and processor before ordering.
Availability, condition, price, and shipping time for 1747-AICR are confirmed during quotation.
