Detailed Product Description

Original Allen-Bradley SLC 500 1746 1747 Processor Module Logic Board

Avoid catastrophic production stops with our certified spare boards for the discontinued Allen-Bradley SLC 500 and MicroLogix families. We specialize in hard-to-find 1746 and 1747 series CPU boards and internal PCBs. These legacy controllers are still vital for thousands of aging but functional industrial systems across North America. Our bench-tested components allow you to keep your legacy lines running reliably without the extreme cost of a full system migration.

Product Highlights

Critical Downtime Solution: Immediate stock of hard-to-find legacy processor boards.
Bench Tested: Every SLC board is verified using RSLogix 500 on original chassis.
Plug-in Replacement: Direct hardware swap for failed 1747-L54x and L55x modules.
Restored Logic: Cleared memory and updated internal capacitors for longevity.
