Product Information

The 1747-L532 is an Allen-Bradley SLC 5/03 modular processor for the Bulletin 1746 SLC system. Its 16K-word memory, runtime editing, real-time clock/calendar and battery-backed RAM support installed machine and process-control applications.

Channel 1 provides DH-485 communication. Channel 0 is an RS-232 port configurable for supported DF1, DH-485, ASCII and Modbus RTU Master communications according to the processor operating system and system design.

Buyer check: confirm the catalog number, series, operating-system revision and installed communication configuration before replacement.

Other SLC 5/03 Versions

1747-L531SLC 5/03 controller with 8K-word memory.
1747-L532SLC 5/03 controller with 16K-word memory; the model shown on this page.
1747-L533SLC 5/03 controller with 32K-word memory.
Selection note: memory size alone does not confirm interchangeability. Verify processor series, OS revision, program requirements and communication configuration before replacement.

Lifecycle, Alternatives & Migration

Official status: Discontinued as of March 31, 2024. The official replacement category is Engineering Replacement.

Is there a direct replacement? No drop-in replacement is identified for 1747-L532. A migration project should assess I/O, communications, program conversion, chassis and enclosure requirements.

Modernization direction: CompactLogix 5380 is the current migration platform promoted for SLC 500 modernization, but selection must be engineered for the installed application.

Other SLC 5/03 memory versions: 1747-L531 (8K), 1747-L532 (16K) and 1747-L533 (32K). SLC 5/04 and SLC 5/05 controllers use different built-in network options and must not be treated as automatic substitutes.

Buyer FAQ

Is 1747-L532 discontinued?
Yes. Rockwell Automation lists March 31, 2024 as its discontinuation date.
Can 1747-L532 be replaced by 1747-L533?
Both are SLC 5/03 processors, but the L533 has 32K memory. Verify operating-system revision, program size and system requirements before replacement.
Does this controller include Ethernet?
No built-in Ethernet port is specified. SLC 5/03 Ethernet connectivity requires an appropriate external interface and engineered network configuration.
What information should accompany an inquiry?
Quantity, destination, required condition, processor series/revision and photos of the installed label when compatibility is critical.
Are certification markings identical on every unit?
Certifications apply when the product is marked. Check the exact unit label and ordered configuration.
