SLC 500 modular chassis

1746A7

1746: BulletinSLC 500 I/O bulletin: chassis, power supplies and I/O modules for the SLC 500 modular system (processors are bulletin 1747).
A: Product typeModular chassis (rack).
7: Slot count7 slots, including slot 0 for the processor.

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 SLC 500 rack-mount applications. The rack is the backplane for a modular SLC 500 system, sized by slot count to the processor, I/O and communication modules a machine needs.

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.

With a 1747-AENTR in slot 0, the existing 1746 rack can keep running as EtherNet/IP remote I/O under a CompactLogix or ControlLogix, so I/O modules can be replaced like-for-like until the rack is converted.
1492-CM1746 conversion modules and pre-wired cables land the existing 1746 terminal-block wiring on the new module without re-terminating field devices.

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.
