Allen-Bradley 1746-A13 SLC 500 Backplane Board

Allen‑Bradley 1746‑A13 is a 13‑slot SLC 500 backplane chassis designed to house a processor and I/O modules in a single 13-slot rack. Part of the SLC 500 family, this modular backplane mounts on a back‑panel and provides the standard 13 slots for SLC 500 modules. The enclosure measures 6.73 in wide by 19.78 in deep by 5.71 in high and weighs about 4.2 lb, making it a compact rack for industrial control installations. The backplane current ratings are 13 A at 5.1 VDC and 3.71 A at 24 VDC, suitable for powering the rack’s circuitry and connected modules. Use this backplane with compatible Allen‑Bradley SLC 500 processors and I/O modules to build a compact discrete control system or small automation project where a 13‑slot modular rack is appropriate.
