SIEMENS 6AV2123-2JB03-0AX0

Overview

SIEMENS 6AV2123-2JB03-0AX0 is a SIMATIC HMI KTP900 Basic operator panel from Siemens Basic HMI family. It is a compact touch screen with integrated key operation, designed for machine-level visualization, parameter setting and alarm handling. It is widely supplied as exchange spare for packaging, conveyor, injection molding and small process control cabinet overhaul and HMI replacement.

Features

SIEMENS 6AV2123-2JB03-0AX0 is equipped with a 9-inch TFT display, 800 × 480 WVGA resolution, resistive touch combined with physical function keys. The front panel meets IP65 protection after correct panel installation to resist dust and splashing liquid. It uses 24 VDC power supply and supports 24/7 continuous industrial operation.

SIEMENS 6AV2123-2JB03-0AX0 carries an integrated Profinet interface for direct connection with SIMATIC S7-1200, S7-1500, S7-300 and S7-400 PLCs. It also supports communication with third-party controllers via standard protocols. Project configuration, download and diagnostics are completed with TIA Portal WinCC Basic software. Onboard LEDs indicate power and communication status for fast on-site inspection. It complies with UL, CE and industrial EMC standards.

Specs

SIEMENS 6AV2123-2JB03-0AX0Platform: Siemens SIMATIC HMI Basic Panel Catalog number: 6AV2123-2JB03-0AX0 Type: KTP900 Basic touch + key HMI Display: 9-inch TFT, 800 × 480 WVGA Touch type: resistive touch Power supply: 24 VDC Interface: Profinet RJ45 Front protection: IP65 Mounting: panel cutout mounting Protection rating: IP20 (rear side) This is not a PLC, VFD or industrial PC; it is a basic operator panel for machine HMI visualization and operation. SIEMENS 6AV2123-2JB03-0AX0 is widely supplied as service replacement spare for HMI panel failure.

Principle

SIEMENS 6AV2123-2JB03-0AX0 runs the HMI project downloaded from TIA Portal. It cyclically reads tags, status information and alarm messages from the connected PLC through Profinet. Touch actions and key inputs are converted into write commands to modify setpoints, trigger control commands or acknowledge alarms. Internal monitoring circuits track backlight, memory and communication status and record fault information.

Applications

SIEMENS 6AV2123-2JB03-0AX0 is deployed for packaging machinery, material handling lines, water treatment skids and standard production machines. It is selected for spare inventory and control cabinet retrofit projects for existing SIMATIC Basic HMI systems.
