6ES7194-1EA00-0XA0 Siemens spare part, 5 g sound absorber

The 6ES7194-1EA00-0XA0 is a sound absorber spare part for the Siemens ET 200X distributed I/O system, specifically the pneumatic module EM148-P DI4/DO2XP. At 5 g it's a lightweight exhaust dampener that clips onto the module's pneumatic port — not a functional I/O component, just noise attenuation for the air exhaust on that slice. Lifecycle is marked current, so it's still a factory-orderable spare through Siemens. No cross-reference or alternative; order the exact code for fit on the EM148-P port.
