Product Introduction
The Siemens 6AV6647-0AK11-3AX0 is a SIMATIC HMI KTP400 Basic Color PN industrial automation module designed for modern control panel applications. This Human Machine Interface (HMI) combines key and touch operation with a 4.3-inch widescreen TFT display capable of rendering 256 colors. Engineered by Siemens, the 6AV6647-0AK11-3AX0 is part of the SIMATIC Basic Panel series, offering a cost-effective upgrade path for older HMI panels such as the OP 77B or TP 177A. It features a PROFINET interface, enabling seamless integration into contemporary automation networks and simplifying data exchange with PLCs and supervisory systems.
Technical Specifications Breakdown
The following key specifications of the Siemens 6AV6647-0AK11-3AX0 are critical for system design and performance evaluation:
-
Display: 4.3-inch TFT with 480 x 272 pixel resolution and 256 colors – provides clear visualization of machine status and process data.
-
Power Supply: Rated 24 V DC (permissible range 19.2 V to 28.8 V) with a current consumption of 0.1 A – ensures low power draw and compatibility with standard industrial power supplies.
-
Environmental Tolerance: Operating temperature from 0 °C to 50 °C (vertical installation) and storage temperature from -20 °C to 60 °C – suitable for factory floor environments.
-
Weight: Only 0.34 kg – simplifies mounting and reduces panel stress.
-
PROFINET Interface: Supports PROFINET IO, TCP/IP, DHCP, SNMP, DCP, and LLDP – enables high-speed communication and easy network configuration.
Industry Applications
The Siemens 6AV6647-0AK11-3AX0 excels in replacement and upgrade scenarios for legacy HMI systems. In packaging lines, its key-and-touch interface allows operators to quickly adjust parameters and view production counts. In material handling systems, the 4.3-inch display provides real-time status of conveyor belts and sorters. The PROFINET connectivity enables direct data exchange with Siemens S7-1200/1500 controllers, reducing wiring and improving response times. For machine builders upgrading from older Profibus or MPI-based HMIs, the 6AV6647-0AK11-3AX0 offers a straightforward migration path to modern Ethernet-based networks.
Compatibility & Integration
This Siemens 6AV6647-0AK11-3AX0 HMI is configured using WinCC Basic V11 SP2 or STEP 7 Basic V11 SP2. It supports communication via PROFINET (including PROFINET IO and IRT), TCP/IP, and other Ethernet protocols. The panel can act as a PROFINET IO device, enabling direct I/O data exchange without a separate controller. It also supports MODBUS TCP/IP and EtherNet/IP for multi-vendor environments. The device includes one Ethernet port and two LED indicators for network status. Note that the unit does not include RS 485, USB, or SD card slots – data transfer is accomplished exclusively over the network.
Selection Guide & Purchasing Advice
Before purchasing the Siemens 6AV6647-0AK11-3AX0, verify your existing panel cutout dimensions (123 mm x 99 mm) and ensure your power supply can deliver 24 V DC with at least 0.1 A. The panel requires a 140 mm x 116 mm mounting cutout (width x height) and a minimum depth of 33 mm behind the panel. For configuration, you will need a PC with Siemens WinCC Basic (V11 SP2 or later). This HMI is ideal for replacing older 4-inch panels or upgrading from text-based displays. For reliable availability and competitive pricing, source your 6AV6647-0AK11-3AX0 from trusted suppliers such as ubest101, which specializes in industrial automation spares.
