Product Description:

The Allen-Bradley 1747-L524 is an SLC 5/02 Programmable Logic Controller (PLC) with 4K of memory and DH-485 communication.¹ While this controller is considered obsolete by Rockwell Automation and is no longer in production, DD Parts Solution currently has units in stock to support existing installations.
