With the Modicon modular safety controller XPSMCM, safety applications can be easily configured, and the system can be flexibly expanded with modules according to the application. This expansion module enables the transmission of secure communication of the internal bus over connected lines for a decentralized system structure. Up to 6 system islands can be connected, each with a distance of up to 50 m and a total cable length of 250 m in a topological line. This module serves as the starting or ending module and features a connection for secure communication. The necessary backplane bus connector is included in the packaging for internal connection. The module has detachable screw terminals. This fieldbus module is compatible with all CPU versions. To support your sustainability goals, detailed information on material contents, environmental impacts, and circular economy is provided.
