Product Description
This lot consists of three Allen-Bradley SLC 500 platform components sold together as a used surplus assembly: a 1747-L40A Fixed Controller (Series C, FRN 6), a 1747-L531 SLC 5/03 Modular Processor (Series E), and a 1746-A2 2-Slot Expansion Rack for Fixed I/O Units (Series A). Additional I/O modules are installed in the racks and are included in the lot; individual catalog numbers for those modules are not confirmed from available photos.
The 1747-L40A is the Allen-Bradley SLC 500 fixed hardware style controller with 24 standard 120V AC inputs and 16 relay outputs, 1K word memory, DH-485 communication, and 120/240V AC line power. Nameplate confirms Series C, FRN 6, manufactured 0597 at FAC. 6N, Made in Japan. The 1747-L531 is the SLC 5/03 modular processor with 8K memory, DH-485 and RS-232 communication ports, Series E. A "PROGRAMMED" sticker on the 1747-L531 references a Thermatool application dated 4/2/15; buyers should plan to reprogram for their own application. The 1746-A2 is the 2-slot expansion rack for fixed I/O units, Series A, manufactured 1297 at FAC. 1P, Made in USA. Both the 1747-L40A and 1747-L531 are Rockwell Automation products that have been discontinued. Items are sold as untested surplus in field-removed condition and are not represented as tested or working.
