The Siemens 3SF4113-1EJ is a flush-mount operator panel with a built-in alphanumeric display — 8 digits of red characters, readable across a panel face. It speaks Profibus-DP, so it plugs straight into a Siemens S7 or any Profibus master without a gateway. The 17 mm cutout and flush bezel mean it sits clean in a control cabinet door or a machine pendant station, not hanging off a bracket.
Integration Note
Flush mounting means the front bezel sits flush with the panel surface — no protruding lip to catch grease or tools. The Profibus-DP connection uses a standard 9-pin D-sub; bus termination and address setting are handled on the unit itself. Red alphanumeric display is readable in low-light machine bays; the 8-digit width fits a short status message or a numeric value like a speed setpoint or fault code.
