Series & Revisions

No series in stock today; request a series above.

Series notes: RSLogix 500 configures 1746 I/O by catalog number only; any series fits the same slot and wiring.

Intended Use

Built for temperature measurement applications. RTD and thermocouple modules measure oven, dryer, extruder and tank temperatures directly in an SLC 500 rack for closed-loop temperature control.

Migration Path

Rockwell Automation has discontinued the SLC 500 platform, including 1746 I/O. Published successor for the SLC 500 1746 I/O: 5069-IY4 (Compact 5000 I/O under CompactLogix 5380).

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.
