Module Processeur CPU General Electric IC695CRU320

Description

The IC695CRU320 is a high-performance redundancy central processing unit designed for the PACSystems RX3i platform. This control module executes real-time machine automation, process synchronization, and high-speed material handling control strategies. It communicates directly with local I/O and intelligent options over an integrated dual backplane bus architecture, merging a high-speed PCI bus for advanced throughput with a serial backplane to allow the simple migration of existing Series 90-30 modules. Operating as the primary computational engine within a Hot Standby (HSB) redundancy framework, a matched pair of these units ensures a resilient architecture that survives single-point failures with a bumpless switchover mechanism. Embedded serial channels utilize standard protocols such as SNP Slave, Modbus RTU Slave, and Serial I/O to link seamlessly with programmer terminals, operator interfaces, and distributed serial devices.

Features

• Incorporates Hot Standby (HSB) technology supporting a fully synchronized redundant pair with online programming and component repair capabilities.
• Provides 64 Mbytes of battery-backed user memory coupled with 64 Mbytes of non-volatile flash memory for secure application block storage.
• Supports dual backplane bus connectivity, ensuring simultaneous electrical compliance with the PCI 2.2 specification and legacy Series 90-30 modules.
• Delivers continuous background tracking diagnostics via a hardware logic toggle switch and an error checking and correction (ECC) single-bit correcting system.
• Implements rapid role switching execution with a maximum logic scan switchover time of 1 scan and a minimum response time of 3.133 msec.
• Features on-the-fly execution for up to 512 internal program blocks with a maximum individual block constraint of 128KB.

Applications

• Critical Process Automation Systems: Providing synchronized backup configurations for chemical, water treatment, and continuous thermal process loops.
• High-Speed Material Handling Lines: Utilizing the dual backplane PCI layer to track multi-axis sorting machinery without process disruptions.
• Power and Infrastructure Remote Telemetry: Deploying serial SNP and Modbus networks to coordinate remote substation RTUs and plant HMIs.

Installation Guidelines

• Ensure the target RX3i backplane rack system is fully powered down before sliding the hardware assembly into its active chassis slot.
• Secure the product within a closed safety enclosure providing an IP20 rating or a minimum NEMA/UL Type 1 configuration to guard against environmental pollutants.
• When locating the system in Class I, Division 2 explosive atmospheres, verify that the containing enclosure is accessible only via specific service tool use.
• Check that only authorized auxiliary memory batteries, such as the IC695ACC302 or IC690RBT001 packages, are attached to the module's battery interface leads.
• Ground all structural backplanes thoroughly according to standard engineering EMI/RFI guidelines prior to putting the redundancy data links online.

Compliance and Certifications

• Class 1 Division 2: Certified safe for use in Groups A, B, C, and D Hazardous Locations.
• ATEX Zone 2: Approved for Zone 2, Group IIC explosive environments when mounted inside an IP54 rated enclosure.
• EU RoHS: Compliant with EU Directive 2002/95/EC under specific Annex exemptions 7(a), 7(c)-I, and 7(c)-III.
