The Siemens SIMATIC HMI KTP900F Mobile (6AV2125-2JB23-0AX0) is a 9-inch widescreen fault-safe mobile panel with key and touch operation, 10 function keys with LEDs, an integrated acknowledgement button and emergency-off switch, PROFINET interface. Configured with WinCC Comfort V13 SP1 + HSP. Mobile use only — needs a 2nd-gen Connection Box and cable. New original, quoted per order, ships in 24h by DHL (3–7 days).
The SIMATIC HMI KTP900F Mobile (order number 6AV2125-2JB23-0AX0) is the largest Safety Integrated panel of the Mobile Panels 2nd Generation — a 9-inch touch-and-keys station with the full mobile safety set: illuminated emergency-stop button, three-stage enabling switch and key-operated switch in one IP65 housing.

What the KTP900F Mobile Is
The complete mobile safety station, largest screen in the family
The F suffix brings the illuminated forced-blocking emergency-stop button, the three-stage enabling switch, the positive-opening STOP button and the key-operated switch, evaluated through the connection box to PL e and SIL 3. Around them sits the same 9-inch visualization as the standard panel — room for diagnostics, recipes and trend views at the point of operation.
Where the extra screen matters in a safety station
Mobile safety stations are often commissioning and service stations too: the operator confirms interlocks, watches axis movements and adjusts recipes. The standard KTP900 Mobile shows the same screens; this type adds the safety controls and the key lock without changing anything else about the workflow.

Ten Keys as Direct I/O, and a Lock on the Mode
Ten direct keys and their LEDs reach the PLC without a script
The physical keys can be assigned as direct S7 inputs and their LEDs as direct outputs — hard behaviour that survives any project mishap. On top sit the 32 configurable touch keys, so the fixed safety-relevant actions and the changing screen commands stay separated.
The key switch keeps modes with the authorized staff
Mode selection on a mobile unit is a supervision question as much as a safety one. The built-in key switch answers it at the handle, which is why service-heavy lines specify the F panel even when the e-stop loop itself stays on the machine.
KTP900F, KTP900 or the Smaller KTP700F
| Characteristic | KTP900F Mobile — this page | KTP900 Mobile (2JB03) | KTP700F Mobile (2GB23) |
|---|---|---|---|
| Safety controls | E-stop, enabling switch, STOP, key switch | None | Same set |
| PROFIsafe | Yes, PL e / SIL 3 | Not supported | Yes |
| Display | 9-inch, 800 x 480 | Same | 7-inch, 800 x 480 |
| Memory | 12 MB | 12 MB | 12 MB |
| Net weight | About 1.6 kg | 1.635 kg | 1.336 kg |
| Lifecycle | Active | Active | Active |
All three dock identically and run the same software. Pick by safety set first, then by screen size: the F panels for mobile safety stations, the 9-inch for the most readable diagnostics.
Compatibility and How to Order
The panel docks into the compact, standard or advanced connection box through KTP Mobile connecting cables of 2 – 25 m and is engineered with WinCC Comfort V13 SP1 or later. The KTP700F Mobile is the 7-inch alternative when the station must stay lighter.

Frequently Asked Questions
Which safety controls are built into the KTP900F Mobile?
An illuminated, forced-blocking emergency-stop button, a 3-stage enabling/acknowledgement switch, a positive-opening STOP button and a key-operated switch.
What safety rating does the station reach?
PL e per ISO 13849-1 and SIL 3 per IEC 61508, evaluated through the connection box by direct wiring or PROFIsafe.
What is the difference from the standard KTP900 Mobile?
Safety hardware only — the standard panel has no e-stop, enabling switch, key switch or PROFIsafe; screen, keys and docking are identical.
Is the screen bigger than the KTP700F Mobile?
Yes, 9 inches against 7, at the same 800 x 480 resolution; both carry the same safety control set.
Which software configures it?
WinCC Comfort V13 SP1 or later in TIA Portal; 12 MB of user memory.
Can the physical keys drive PLC signals directly?
Yes, the ten keys can be assigned as direct S7 inputs and their LEDs as direct outputs, independent of the touch layer.
Which docking hardware does it use?
The same compact, standard or advanced connection boxes and 2 – 25 m KTP Mobile connecting cables as every 2nd Generation panel.
How heavy is it in daily use?
About 1.6 kg — noticeably more than the 7-inch F panel at 1.336 kg, which is the usual trade against the larger screen.
Is it sealed against the working environment?
IP65 all-round, drop-tested to 1.2 m per IEC 60068-2-32, rated 0 to +45 °C.
Is the hardware genuine, and how do I get a quote?
Genuine Siemens hardware sourced through Siemens-authorized distribution partners; CAN Electric is an independent channel trader, not Siemens and not a factory-authorized distributor. Email sales@can-electric.com with quantity, condition and delivery country.
