Intended Use | Built for discrete sensing applications. Inputs read limit switches, proximity and photoelectric sensors, pushbuttons and auxiliary contacts into an SLC 500 rack, the position and status signals the ladder program runs on. | ||||||||
Migration Path | Rockwell Automation has discontinued the SLC 500 platform, including 1746 I/O. Published successor for the SLC 500 1746 I/O: the equivalent Compact 5000 (5069) or 1769 Compact I/O module.
A like-for-like replacement or a repair keeps the existing program, wiring and panel layout; a migration is a project. Both are listed on this page so the choice can be made on lead time and budget. | ||||||||
