Features:
- SIMATIC S7-1200, Communication Board
- CB 1241, RS485, terminal block,supports Freeport
- The Communication Board (CB) is a compact plug-in card that can be directly inserted into the front slot of any SIMATIC S7-1200 CPU
As a dedicated signal board, it can be directly inserted into the expansion slot on the front panel of the S7-1200 CPU, eliminating the need for additional DIN rail space and providing a cost-effective and compact serial data cascading solution for the controller.
Its core function is to establish point-to-point physical connections, enabling the PLC to easily interact with various peripheral devices in industrial applications. The board offers high flexibility and multi-protocol compatibility in terms of communication protocols and connection methods.
The 6ES7241-1CH30-1XB0 Siemens Communication Board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 6ES7241-1CH30-1XB0 relies on differential voltage signal transmission and integrated protocol drive to achieve low-level data interaction. Once operational, the board obtains power through its internal 5V DC backbridge bus and converts the logic level signals from the CPU into RS485 standard two-wire (A and B lines) differential voltage signals for transmission. This differential characteristic gives it strong common-mode interference immunity.
