Siemens 6AV2125-2JB23-0AX0 Overview

The Siemens SIMATIC HMI KTP900F mobile panel module 6AV2125-2JB23-0AX0 is a second-generation Simatic HMI mobile panel. This panel offers you mobile operation as well as monitoring of your production process. The entire 2nd Generation system of mobile panels consists of three parts: A Mobile Panel, a connection box, and a connecting cable. These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry HMIs from other manufacturers such as FANUC and Yaskawa.


The 6AV2125-2JB23-0AX0 comes with a 9” wide screen.

The panel structure is designed as a fail-safe HIMI. The 6AV2125-2JB23-0AX0 has the following features on the panel:

· Keyswitch

· Enabling button

· Cover of the USB port

· Handle

· Function Key blocks

How to use the Siemens 6AV2125-2JB23-0AX0

The fail-safe button is designed for ease in accessibility. There are protective measures designed for the emergency stop /stop button. It is equipped with bumpers to keep it from impact damage. The bumpers are positioned in such a way to allow for activation of the Emergency Stop / Stop button can be activated upon impact. 

There are safety measures that must be adhered to when working in and on electrical systems. First, you must make sure the system is turned off. Second, secure the system to keep it from turning back on. Third, check your system to ensure it is de-energized as some of the currents may remain after being switched to the OFF position. Fourth, you must ground and short the system. Last, cover over any parts that are adjacent and are still live. You may also shield these adjacent live parts.

The mobile panel 6AV2125-2JB23-0AX0 comes with an open compartment for the terminal. In order to replace an SD card or a connecting cable, you will be working with the open terminal compartment. The following sequence must be adhered to when connecting:

1. SD memory card, if needed

2. KTP mobile connecting cable

3. Connection box

4. Configuration PC, if needed

The 6AV2125-2JB23-0AX0 has a slot for an optional SD memory card as do all of the 2nd Generation Mobile Panels. The SD card is used for automatic backup purposes and is also used as a back-up storage function. The requirements for replacement must be closely adhered to in order to avoid injury. First, de-energize the unit, then open the terminal compartment while making sure the connection cable is not attached. Then you tune the storage medium, so you have the contacts pointing to the motherboard. You then push the storage board into the slot with a plastic tool.


What makes the Siemens panel module 6AV2125-2JB23-0AX0 perfect for the industrial setting? Its design is specifically engineered to resist high falls as it has high impact resistance qualifications. Fortified with a high protection class, it is prepared to work when you are operating with chemicals and cleaning agents. It is designed to resist both chemicals and cleaning agents found in the industrial setting. Additionally, the Siemens mobile panel comes with a protective film to keep it from getting scratched or dirty during operation.

There is storage media available for this unit. You can use either the SIMATIC HMI memory card or a USB flashcard for memory. This will store media on the device and back it up as well as share data to the mobile panel.
