Siemens 6AV2125-2AE13-0AX0 SIMATIC HMI Connection Box Standard PROFINET IP65 HMI Accessory

The Siemens 6AV2125-2AE13-0AX0 is a SIMATIC HMI Connection Box Standard, a wall-mounted interface unit for Mobile Panels that provides PROFINET and PROFIsafe connectivity with an integrated three-port Ethernet switch. It evaluates the emergency stop, STOP and acknowledgement buttons either through direct wiring or via PROFIsafe, reaching Performance Level PLe and SIL 3, and carries IP65 protection for machine-side mounting.

Selection Notes

The Standard connection box reconnects the machine only after the emergency stop circuit is physically interrupted and restored, whereas the Advanced variant supports reconnection without interrupting the circuit; pick the Standard box where a hard circuit break on E-stop release is the required safety behavior. Both direct-wired and PROFIsafe evaluation paths are built in, so the same box works whether the Mobile Panel's safety relay is wired conventionally or handled over PROFIsafe. SIL 3 / PLe puts it at the top safety category used in most machinery applications, and the integrated 3-port switch avoids a separate PROFINET switch at the wall-mount point.

Applications

Used as the fixed wall-mount docking point for SIMATIC Mobile Panels on machines requiring hardwired emergency-stop circuit interruption on connect and disconnect, such as production cells where operators dock and undock a corded pendant.
