Schneider 140CHS11000 is a hot-standby module from Schneider Electric’s Modicon Quantum series, designed to enhance the reliability and availability of PLC systems.

Key Features

• Function Positioning:
  Serves as a hot-standby unit capable of rapidly switching to the backup controller when the primary controller (such as 140CPU 43412A/B, 43452A/B) fails, ensuring uninterrupted industrial operations.
• Communication Method:
  Utilizes 10 Mbit/s fiber-optic transmission with a switchover time of 13–48 ms, supporting the Modicon Quantum remote I/O network.
• Power & Consumption:
  Powered by 24 V DC with power consumption under 10 W.
• Environmental Adaptability:
  Operating temperature: 0–60 °C
  Storage temperature: –40–85 °C
  Protection rating: IP20
  Humidity: 5%–95% (non-condensing)
• Dimensions & Weight:
  Approx. 310 mm × 220 mm × 80 mm
  Weight: ~1 kg (about 0.5 kg after packaging)

Typical Application Scenarios

• Critical Industrial Control:
  Industries with strict continuous-operation requirements such as oil & gas, chemical, power, water treatment, transportation, and manufacturing.
• System Redundancy:
  New or retrofit PLC systems that require seamless primary/backup controller switching to prevent downtime caused by single-point failures.

In summary, the Schneider 140CHS11000 is a hot-standby module designed for Modicon Quantum PLCs, offering high-speed fiber-optic communication, fast switchover capability, and strong environmental robustness—helping users build highly reliable automation control systems.
