Schneider Electric BMEH586040 Redundant Processor

Schneider Electric's BMEH586040 is a redundant processor module for the Modicon M580 family, delivering hot-standby redundancy to keep critical automation running in the event of a CPU fault. The module provides 64 MB of RAM for program and data within the global memory pool, enabling robust storage for control logic and data. In typical M580 deployments, the BMEH586040 supports up to 61 Ethernet devices and can manage up to 31 remote I/O racks of X80 and Quantum IO, supporting scalable, networked automation. It is used in medium- to large-scale industrial automation where continuous operation and reliable networked I/O are required.
