The isolated RS422/485 interface (X.27) connects via a 15-pin sub-D connector and supports cable runs up to 1 200 m — suitable for distributed field devices across a plant floor. ## Power draw and physical fit The module draws 70 mA from the S7-300 backplane bus at 5 V DC and up to 240 mA from the external 24 V DC supply (L+, M, GND via three screw terminals). Maximum power loss is 5.8 W. Dimensions are 40 mm wide, 125 mm high, and 120 mm deep — it occupies one standard S7-300 slot width and mounts directly on the DIN rail in the enclosure. The configuration package is included on CD, and customer-specific drivers are reloadable via the 15-pin sub-D interface.","metaTitle":"Siemens 6ES7341-1CH01-0AE0 CP 341, RS422/485, EOL Spare Part","metaDescription":"Siemens 6ES7341-1CH01-0AE0 CP 341 communications processor, RS422/485, EOL spare part.
