Product Introduction
The Schneider 140CHS41010 Hot Standby Kit is a critical component designed to ensure high availability and system reliability within Schneider Electric’s Modicon PLC systems. This kit enables the implementation of a hot standby (redundant) configuration, allowing one CPU to take over immediately if the primary CPU fails, thus minimizing downtime and maintaining uninterrupted control.
Specifically engineered for industrial automation and control environments, the 140CHS41010 kit facilitates seamless failover without loss of data or control continuity. Its integration into the Modicon platform enhances system robustness in critical applications such as manufacturing, process control, and infrastructure management.
