Schneider 140CRA93100 is a redundancy adapter module specifically designed for the Modicon Quantum series, serving as a critical component to enable hot-standby redundancy for CPU modules. Its core function is to establish reliable data synchronization and seamless failover between primary and backup CPUs, ensuring uninterrupted operation of industrial automation systems—especially in safety-critical or high-availability scenarios (e.g., chemical plants, power stations). Below is its comprehensive specification:
- Manufacturer: Schneider Electric
- Product Series: Modicon Quantum (industrial-grade PLC platform for large-scale automation)
- Model: 140CRA93100
- Product Type: Redundancy adapter module (dedicated to CPU hot-standby redundancy)
- Compatibility:
- Exclusively works with Modicon Quantum series racks (10-slot, 16-slot, etc.).
- Compatible with Quantum high-performance CPUs that support redundancy (e.g., 140CPU67060, 140CPU67160, 140CPU67160S).
- Requires pairing with two identical CPUs (primary + backup) and matching Quantum power modules (e.g., 140CPS12400) for a complete redundancy system.
- Physical Attributes:
- Weight: Approximately 0.3 kg.
- Form Factor: Modular design, fitting standard Modicon Quantum rack slots (occupies 1 slot per module).
- Protection Class: IP20 (relies on the control cabinet for environmental protection; suitable for indoor industrial environments).
- Hot-Standby Redundancy Enablement: Acts as a "bridge" between primary and backup CPUs, enabling real-time data synchronization (including program logic, I/O status, and process variables) with a synchronization delay of < 5 ms. This ensures that the backup CPU is always in a "hot" state, ready to take over immediately.
- Seamless Failover: Automatically detects faults in the primary CPU (e.g., hardware failure, communication loss) and triggers failover within < 10 ms. The backup CPU takes over control without interrupting the system’s output or process, avoiding production downtime.
- Redundancy Status Monitoring: Integrates status detection logic to monitor the health of both primary/backup CPUs and the redundancy link. Faults (e.g., synchronization failure, module disconnection) are transmitted to the system controller or HMI via the rack bus for alerting.
- Dual Redundancy Links: Equipped with two independent synchronization ports (fiber-optic or copper, depending on configuration) to prevent single-point failure of the redundancy link, enhancing the reliability of data transmission between CPUs.
- Plug-and-Play Integration: Requires no complex hardware configuration—simply install the module in the Quantum rack, connect it to the CPUs via dedicated cables, and configure redundancy parameters through Schneider’s Unity Pro software.
- Operating Temperature: 0°C – 60°C (matches the working temperature range of Quantum CPUs and racks, suitable for most industrial indoor environments)
- Storage Temperature: -40°C – 85°C (for transportation or idle storage)
- Relative Humidity: 5% – 95% RH (non-condensing; resistant to humid conditions in water treatment plants or food processing facilities)
- Vibration Resistance: 5 g (10 – 150 Hz, per IEC 60068-2-6) – ensures stability under mechanical vibration (e.g., near industrial pumps or compressors)
- Shock Resistance: 30 g (11 ms, per IEC 60068-2-27) – withstands occasional mechanical shocks during installation or maintenance
- Safety Certifications: CE (complies with EU EMC and Low Voltage Directives), UL 508 (US industrial control equipment safety standard), CSA C22.2 No. 14 (Canadian safety standard)
- Industrial Standards: IEC 61131-2 (compatible with standard industrial control system design requirements)
- Hazardous Area Compliance: Optional ATEX certification (for use in Zone 2 hazardous areas, e.g., oil refineries or chemical plants with flammable gases) – confirm with Schneider’s official datasheet for specific versions
- Programming/Configuration Software: Requires Schneider Unity Pro (V11.0 or later) or EcoStruxure Control Expert – the software provides a dedicated "Redundancy Configuration" interface to set parameters such as:
- Primary/backup CPU assignment
- Synchronization link type (fiber/copper)
- Failover trigger conditions (e.g., CPU heartbeat loss, I/O communication failure)
- Redundancy status monitoring alerts
- Diagnostic Functions: Through the software, users can view real-time redundancy status (e.g., "Primary Active," "Backup Standby"), fault logs (e.g., synchronization errors), and perform manual failover tests (for system verification).
The 140CRA93100 is essential for systems where downtime causes significant economic losses or safety risks, including:
- Process Industry: Oil & gas refineries (emergency shutdown systems, ESD), chemical plants (reactor temperature/pressure control), and pharmaceutical facilities (batch process safety loops).
- Energy & Utilities: Power generation plants (turbine auxiliary control), water/wastewater treatment (pump station operation), and nuclear auxiliary systems.
- Heavy Manufacturing: Steel mills (rolling mill speed synchronization), pulp/paper plants (digester pressure control), and automotive assembly lines (high-speed production line control).
- For complete redundancy system design (e.g., rack redundancy, power redundancy), the 140CRA93100 must be used with other Quantum redundancy components (e.g., 140CRP93200 redundancy cable, dual power modules).
