Product Overview
The Schneider 140CHS21000 Hot Standby Kit is a high-availability automation component designed for the Modicon Quantum series / PLCs. This kit enables a dual-CPU architecture, allowing one CPU to act as the active processor and another to serve as a fully synchronized backup (hot standby), ready to take over instantly in the event / a primary failure.
This seamless redundancy ensures continuous operation for critical applications in process automation, manufacturing control, energy management, and infrastructure systems. With rapid switchover (typically within milliseconds), the kit dramatically reduces system downtime and minimizes the risk / production losses or safety incidents.
The 140CHS21000 Hot Standby Kit is compatible with various Quantum CPU models and is widely adopted in industries where system availability and process continuity are paramount.
