Allen-Bradley 1747-AIC is an isolated link coupler for the SLC 500 modular I/O family, providing DH-485 network connectivity for a connected SLC 500 controller. It fits in a 1747 backplane slot in a Series A, Revision A configuration and delivers galvanic isolation between the DH-485 trunk and the SLC 500 processor, helping protect the controller from network transients. This module is used to interface SLC 500 systems with DH-485 networks in industrial automation setups and is part of Rockwell's DH-485 networking ecosystem for the SLC 500 family.
