Intended Use

Built for mid-size standalone machine control applications. The MicroLogix 1500 pairs a processor with a base unit for small to mid-size machines needing more I/O and faster execution than a brick controller, expandable with 1769 Compact I/O.

Migration Path

Rockwell Automation has discontinued the MicroLogix 1500. Published successor for the MicroLogix 1500: Micro870 (2080-L70E) or CompactLogix 5370 L1 (1769-L16ER-BB1B / L18ER-BB1B) where 1769 expansion I/O must be kept.

Connected Components Workbench's RSLogix 500 program converter moves the program into a Micro870 project; for a Logix target use the Studio 5000 project translation tool.
The 1769 Compact I/O attached to a 1764 base is reused directly on a CompactLogix 5370 L1/L2, which is the path when the I/O count is what drove the 1500.

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.

Common 1764-LSP failures

Failure patterns we regularly see on MicroLogix 1500 processor / base hardware like the 1764-LSP:

Processor will not communicate with the base unit: connector damage
Output relays welded or burned on relay-output bases
Program lost after a power event: memory module or battery failed
Channel 0 / Channel 1 serial port damage
Power supply section failure in the base unit

Repair or replace?

ReplaceReplacement MicroLogix units are usually surplus or refurbished. Replace the 1764-LSP if it is dead or faulting and you have a current program backup. Check that the series and firmware match your project first. A replacement 1764-LSP is sourced on request, so compare its lead time with a repair before deciding.

RepairRepair keeps the exact 1764-LSP your program and licensing were validated on and can preserve the memory contents when no backup exists. It is usually the better call for battery-holder corrosion, a damaged comm port or a failed power section when matching stock is scarce. The two 1764-LSP symptoms we see most often are “Processor will not communicate with the base unit” and “Output relays welded or burned on relay-output bases”. If a replacement is already installed, repairing the failed 1764-LSP gives you a tested spare on the shelf, which is worth more on an older platform where a matching unit can take time to source. Each 1764-LSP we repair goes back function-tested with a 1-year warranty.
