Part Number Decoder | SLC 500 digital output module 1746OBP1616
Decoded from the Rockwell Automation catalog-number structure. Series and firmware revision are printed on the product label, not encoded here. | ||
Intended Use | Intended for on-off actuation of valves, contactors and indicators applications. Solid-state outputs switch 24V DC or AC loads such as solenoid valves, contactor coils and indicator lights on SLC 500-controlled machines and process skids. | ||
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. | ||
