Part Number Decoder | SLC 500 thermocouple input module 1746NT88
Decoded from the Rockwell Automation catalog-number structure. Series and firmware revision are printed on the product label, not encoded here. | ||
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 (x2) (Compact 5000 I/O under CompactLogix 5380).
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. | ||
