Siemens 6AV2125-2AE23-0AX0 HMI Connection Box

The Siemens SIMATIC HMI Connection Box Advanced for Mobile Panels (6AV2125-2AE23-0AX0) is a wall-mounted, IP65-rated interface that connects SIMATIC HMI Mobile Panels 2nd Generation to PROFINET networks and PROFIsafe, enabling safe, networked operator interfaces in harsh industrial environments. This advanced connection box includes an integrated switch, an MRP client, and IRT, and it supports terminal detection, the connection of safety relays, and emergency-stop circuit bridging to simplify machine-safety wiring. Powered from 24 VDC, it draws about 96 mA and its dimensions are 76 mm x 230 mm x 145 mm, with an operating temperature range of 0 to 55 °C and a starting current inrush I²t of 0.16 A²·s. Designed specifically for Mobile Panels, it is documented for use with the SIMATIC HMI Mobile Panels 2nd Generation and is suitable for control cabinet or machine-side installation where PROFINET connectivity and integrated safety features are required. With its rugged enclosure and Siemens engineering, this box provides a reliable bridge between HMI devices and industrial networks, helping ensure stable data exchange, straightforward installation, and clear integration of safety circuits in automation lines.
