Low-Cost Hot Standby Kit 140CHS41020 - Schneider Electric

Affordable System Uptime: Schneider Electric 140CHS41020 Hot Standby Kit

The Schneider Electric 140CHS41020 provides a cost-effective redundancy solution for Quantum PLCs. This hot standby kit ensures continuous process operation by automatically switching to a backup CPU if the primary fails, minimizing downtime in critical applications.

Core Redundancy Performance

• System Scale: Protects systems from small I/O racks up to large configurations with 128 slots.
• Fast Failover: Achieves a typical redundancy switch time of 150 milliseconds.
• Precision Synchronization: Maintains sync accuracy of 1 millisecond between primary and standby CPUs.
• I/O Support: Compatible with standard digital I/O and analog signals like 4-20 mA and 0-10 V.
• High Reliability: Estimated MTBF (Mean Time Between Failures) exceeds 100,000 hours.
• Electrical Safety: Provides 1500 V isolation between I/O and power rails.

Configuration and Connectivity

• Synchronization Links: Uses fiber optic cables for high noise immunity over distance or shielded copper for shorter runs.
• Power Flexibility: Works with 24 V DC or 110 V AC compatible Quantum power supplies.
• Power Consumption: Typical draw is 20 watts per CPU during normal operation.
• Environmental Range: Operates from -20°C to +60°C and stores from -40°C to 85°C.
• Module Weight: Components designed for standard integration; typical rack weight applies.

Optional Features and Tools

• Extended Fiber Optics: Optional cable lengths up to 30 meters for greater physical separation.
• Enhanced Availability: Optional spare CPU for immediate hot-swap replacement.
• Power Protection: Optional surge suppression modules for input power lines.
• Fast Recovery: Backup configuration on USB for rapid system restore.
• Easy Setup: Local I/O mapping tool simplifies commissioning.

Implementation and Support

• Ideal For: Water treatment, power distribution, and production lines where unplanned stoppages are costly.
• Key Advantage: Delivers high-availability redundancy at a lower entry cost, making system protection more accessible.
• Package Contents: Kit includes necessary synchronization modules, cables (copper standard), and documentation.
• Global Shipping & Support: In stock for fast shipment via FedEx, UPS, or DHL. Technical support is available for setup.
