ControlLogix 5580 and GuardLogix 5580 controllers (1756-L8)
29 Allen-Bradley ControlLogix / GuardLogix 5580 (1756-L8) catalog numbers, each with the ratings and the lifecycle status shown on its Rockwell product page (read on 3 November 2026). TDL quotes these parts as spares or as part of a project, and handles configuration, programming and commissioning on site.
- Every ControlLogix 5580 controller has one embedded Ethernet port at 10/100/1000 Mbps.
- The ControlLogix 5580 range runs from 3 MB (1756-L81E) to 40 MB (1756-L85E) of user memory.
- GuardLogix 5580 controllers (1756-L8xES) are listed with the 1756-L8SP safety partner.
- Rockwell lists the conformal-coated 1756-L8xEK, 1756-L8SPK, the 1756-L8xEP process controllers and 1756-L81E-NSE as End of Life, discontinued December 31, 2026, with XT models as direct replacements.
How to read the catalog number
- The digit after L8 follows memory: L81 = 3 MB, L82 = 5 MB, L83 = 10 MB, L84 = 20 MB, L85 = 40 MB.
- S = GuardLogix safety controller; P = process controller; K = conformal coated; XT = eXTreme environment (conformally coated); -NSE = No Stored Energy.
