The Siemens 6ES7274-1XH00-0XA0 is a spare-part simulator module for the SIMATIC S7-200 line, providing 14 manual input switches for testing and commissioning without live field wiring. It measures 22 mm deep and 91 mm wide, fitting compactly in the S7-200 rack. It is listed as current production (lifecycle stage current), so it remains available for BOM continuity.
Panel fit and cross-check
The 22 mm depth seats flush in the standard S7-200 mounting; no additional DIN-rail space beyond the 91 mm width is claimed. The 6ES7148-4FA00-0AB0 (ET 200S digital input) is a different form factor and function — it does not drop in as a substitute for this simulator module.
