SLC-500

This PLC is the stalwart of the Allen-Bradley range – PLC5s have all but disappeared, but the SLC-500 remains, albeit now categorised as a ‘Active Mature’ product, and no doubt heading towards end of life with price increases, scarcity and resorting to eBay to find product of unknown reliability.

It is recommended that SLC-500 users start thinking about a migration, probably to CompactLogix.

  • Preparing Documentation:
    • IO Lists
    • Device Lists
    • Electrical Drawings
