Siemens 6ES7241-1CH30-1XB0 – SIMATIC S7-1200 CB 1241 RS485 communication board
The Siemens 6ES7241-1CH30-1XB0 is a SIMATIC S7-1200 CB 1241 communication board designed to add RS485 serial communication to compatible S7-1200 controllers. It is used for point-to-point data exchange with field devices, drives, meters and other serial communication equipment.
This CB 1241 board supports Freeport communication, ASCII communication via library function and Modbus RTU master or device operation. The terminal block connection makes it suitable for compact controller installations where an integrated communication expansion is required.
The communication board is installed directly on the S7-1200 CPU and is intended for automation systems that require reliable RS485 communication without adding a larger external communication module.
