Schneider 140CHS41020 Hot Standby Kit

Why This Kit Ensures System Redundancy

This Hot Standby kit provides automatic failover for critical processes. You get a complete Schneider 140CHS41020 for Modicon Quantum PLCs. It includes two cables and one configuration switch. Therefore, your system can switch to a backup CPU without any manual intervention.

Technical Specifications and Physical Details

The Schneider 140CHS41020 connects two Quantum processors in a primary-standby pair. Each cable measures exactly one meter in length. The kit contains a dedicated fibre optic receiver module for high-speed sync. You will find the configuration switch inside the package for setting node addresses. This kit stores no energy on its own. Instead, each CPU holds the redundant logic and data tables. Consequently, the backup unit takes over within a single scan cycle.

Below is the detailed breakdown of the hardware specifications.

Installation and System Integration

This kit works exclusively with Quantum Hot Standby processors. You connect the fibre optic cables between both CPU racks. The 140CHS41020 configuration switch sits on the primary rack. Set one CPU as master and the other as standby before startup. Always verify the fibre optic cable orientation during installation. Dirty connectors will cause sync loss and failover errors. Clean each tip with a proper lint-free wipe before plugging it in.
