Siemens 6AV6647-0AH11-3AX0 HMI Operator Panel

Siemens 6AV6647-0AH11-3AX0 is the KP300 Basic Mono PN operator panel, a compact HMI designed for Siemens PLC systems. It features a 3.6-inch FSTN monochrome LCD (black/white) with a 240 × 80 pixel resolution and a display area of about 87 mm × 31 mm, with a backlight that can emit in four colors (white, red, green, yellow) and an MTBF of 50,000 hours. Input is provided by a 10‑function keypad plus system keys and a numeric keypad, enabling straightforward local operator interaction. It communicates over PROFINET for direct integration with SIMATIC S7 and is configurable from WinCC Basic V11 or STEP7 Basic V11. The device ships with open‑source software on the enclosed CD, consistent with KP300 Basic mono PN offerings. This HMI is well suited for compact operator interfaces in small- to mid‑size automation tasks, where concise visualization and keypad input are adequate for monitoring and controlling processes within the Siemens automation ecosystem.
