- Use 1747-L511 only as the documented 1K-word SLC 5/01 modular controller
- Match the processor to the approved SLC 500 chassis, power supply and DH-485 network
- Preserve the online program, data tables, node settings and memory backup before removal
1747-L511 is an Allen-Bradley SLC 5/01 1K modular controller for the SLC 500 platform.
Allen-Bradley 1747-L511 is an SLC 5/01 modular controller with 1K words of memory and a DH-485 slave communication interface for basic SLC 500 control applications. 1747-L511 is the complete processor catalog number; chassis, power supply, I/O modules, programming interface, EEPROM memory module and replacement controller are separate products.
Before installation or replacement, verify the complete nameplate, compatible companion hardware, wiring or network design, saved configuration and commissioning plan.
Availability, condition, price, and shipping time for 1747-L511 are confirmed during quotation.
