6AV2123-2DB03-0AX0 Descripción general
An HMI (Human Machine Interface) panel is an industrial operator terminal that sits between the human operator and the PLC (programmable logic controller) within the automation hierarchy. It visualizes machine states, alarms, and process values, and accepts operator commands via touch and mechanical keys. The KTP400 Basic belongs to Siemens' SIMATIC Basic Panels family, the entry tier of the SIMATIC HMI range designed for small machines and local operator stations.
Key features include the 4-inch TFT widescreen with 65,536-color rendering, combined 4-key membrane keypad plus resistive touch operation, and a single industrial Ethernet (PROFINET) interface for PLC communication. Active power input is typically 3 W with an inrush I2t of 0.2 A2s. The panel provides Flash storage and 10 Mbyte of memory available for user data, plus a hardware real-time clock with retentive behavior and approximately 6 weeks of backup, synchronizable over the network. An acoustic buzzer output is integrated; no speaker is fitted.
Technically, the KTP400 Basic is built around an ARM processor and runs runtime visualization projects created in WinCC Basic V13 or newer (within TIA Portal). The front face is rated IP65 (NEMA Type 4 / 4x) for washdown and dust-exposed mounting, while the rear housing is IP20 for control-cabinet installation.
Typical applications include small machine operator stations, pump and fan skids, conveyor controls, and building or utility automation where a compact, low-power visualization terminal is required. Its PROFINET interface connects directly to S7-1200 and S7-1500 PLC families.
Design consideration: verify panel cutout dimensions and front IP65 sealing with the supplied gasket, and confirm TIA Portal version compatibility before project download.

Aplicaciones típicas
6AV2123-2DB03-0AX0 es adecuado para 6 aplicacións: Small Machine Operator Station, Pump and Water Treatment Skids, Conveyor and Material Handling Controls, Building and Utility Automation, Machine Retrofits and Legacy Replacements, OEM Panel Integration and Marine Applications.
Small Machine Operator Station
The 6AV2123-2DB03-0AX0 is purpose-built as the local operator terminal of small machines such as packaging tabletop units, labeling stations, and compact assembly fixtures. Its 4-inch 480 x 272 TFT with 65,536 colors is sufficient for recipe screens, alarm lists, and trend views on machines with fewer than roughly 100 screen objects, while combined key/touch operation lets operators confirm critical actions with a physical key even with gloves on. At a typical 3 W power draw it can share the machine's existing 24 V control supply without upsizing. Because it is configured from WinCC Basic V13 inside TIA Portal alongside the S7-1200 PLC project, one engineering environment covers PLC and HMI, cutting commissioning time. The IP65 front withstands dust and washdown spray common around small machinery.
Recomendado
Pump and Water Treatment Skids
On pump skids, dosing systems, and small water treatment trains, the 6AV2123-2DB03-0AX0 displays tank levels, pump status, and start/stop commands over its single PROFINET interface to an S7 PLC. The retentive hardware real-time clock with approximately 6 weeks of backup timestamps fault events and run-hour logging even after control power loss, and network clock synchronization keeps records consistent across multiple panels. The buzzer provides acoustic alarm annunciation in noisy plant rooms where a speaker is unnecessary. The IP65/NEMA 4x front rating tolerates the humid, splash-prone environment near pumps and pipework when panel-mounted with the supplied gasket. Its 3 W typical consumption suits solar-buffered or low-power remote cabinets common in distributed water infrastructure.
Recomendado
Conveyor and Material Handling Controls
Conveyor spurs, sortation chutes, and lift stations use the 6AV2123-2DB03-0AX0 as a compact local panel for mode selection, jam diagnostics, and manual jog commands. The four mechanical keys provide reliable, tactile confirmation for safety-relevant mode changes, while the resistive touchscreen accepts operator input even when worn gloves or dusty fingers are involved - a frequent real-world condition in material handling. The 480 x 272 display renders zone diagrams and fault locations clearly at a glance. Over PROFINET, cycle and jam data exchange with the S7 line controller runs on the same cable that downloads the HMI project. With only 3 W typical draw and 0.2 A2s inrush, multiple panels can be powered from one branch of the 24 V distribution.
Recomendado
Building and Utility Automation
In building services and utility plants - HVAC skids, boiler rooms, compressed-air stations, and generator switchgear - the 6AV2123-2DB03-0AX0 serves as the wall-mounted local HMI behind IP65-front installation. Its marine approvals (GL, ABS, BV, DNV, LRS, Class NK per the datasheet) additionally make it valid for shipboard HVAC and utility boards, a niche where ordinary commercial touchscreens are not certifiable. The 65,536-color 4-inch display is adequate for setpoint editing, schedule display, and alarm acknowledgment typical of utility supervision. The synchronizable real-time clock supports time-stamped logging across the network, and the buzzer signals new alarms without requiring a horn relay. Configuration from WinCC Basic V13 keeps the HMI consistent with the controlling S7 PLC project.

Machine Retrofits and Legacy Replacements
The 6AV2123-2DB03-0AX0 is widely used to replace failed or obsolete KTP400 Basic units in installed machines. Siemens publishes an official Basic Panels migration guide describing replacement of predecessor devices with Basic-series successors, so technicians can swap the panel in the same 4-inch cutout and reload the existing WinCC Basic project over PROFINET with minimal rework. Third-party verified substitutes such as the Radwell keypad membrane (6AV2123-2DB03-0AX0-SUB-KEYPAD, 131.5 mm x 107.5 mm viewing assembly) address keypad-only failures where a full panel swap is unnecessary. Availability from many distributors (DigiKey ships same day; Octopart aggregates 10 sources) shortens downtime windows during retrofit projects.

OEM Panel Integration and Marine Applications
Original equipment manufacturers building enclosed control panels benefit from the 6AV2123-2DB03-0AX0's combination of compact 4-inch footprint, IP65/NEMA 4x front sealing, and a certification package that includes CE, cULus, RCM, KC plus six maritime class approvals (Germanischer Lloyd, ABS, Bureau Veritas, DNV, Lloyd's Register, Class NK). This lets one panel design serve both industrial and marine OEM product lines without redesign. The ARM-based runtime handles standard Basic Panel screens responsively, the buzzer covers audible alarm requirements, and the 3 W typical load simplifies thermal and power budget calculations inside sealed enclosures. TIA Portal-based configuration lets OEM template one HMI project across machine variants, reducing per-unit engineering cost.

Notas de diseño
Verify the exact MLFB suffix before ordering or swapping KTP400 variants. The suffix letters (2DB03, 2MB03, 2MA03) encode interface and approval differences that are not visible from the product photo. Field reports of third-party-branded 'drop-in' substitutes (e.g., mislabeled -2MA03 units sold as -2DB03 replacements) exist, so purchase from authorized distributors and check the rating plate after delivery.
For panel mounting, follow the Siemens Basic Panels installation instructions for the 4-inch cutout and use the supplied gasket uncompressed-to-specified-tolerance to maintain the IP65 / NEMA 4x front rating. The rear is only IP20, so the panel body must reside inside a cabinet. Respect the 0.2 A2s inrush I2t rating when selecting the 24 V supply and any in-line protection so breakers or fuses do not nuisance-trip at power-up.
At 3 W typical active input, thermal load inside a sealed enclosure is negligible, but confirm the 24 V DC supply stays within the panel's allowed voltage tolerance at all loads (measure at the terminal, not at the supply). Configure real-time clock synchronization over PROFINET rather than relying solely on the ~6-week retentive backup, especially in systems where alarm time-stamping feeds quality records.
