This AC‑powered PanelView 550 variant operates from 120 V AC (47–63 Hz) and draws up to 45 VA, making it suitable for rugged industrial panels. It configures with PanelBuilder32 software and provides 170 KB of application runtime plus 240 KB of nonvolatile RAM for objects and text/bitmaps, with ATA memory card support for program storage. A built‑in real‑time clock (battery‑backed) timestamps critical data, and the unit offers serial and DH+ networking options typical of the PanelView 550 family, including RS‑232 printer/DF1 connectivity. As part of Rockwell’s PanelView Standard 550 line (Series H), it supports firmware FRN 4.10 in configured units. The 2711-K5A8 is designed for indoor use and can be installed in NEMA Type 12/13 or 4X (indoor) enclosures to achieve IP54/IP65 protection when properly enclosed. Typical shipping weight is about 6 lb with approximate carton dimensions of 14 × 11 × 8 inches.
