Description
GE IC695CRU320
- Technical Specifications:
- Processor: 1 GHz Intel Celeron M
- Memory: 64 MB battery-backed RAM; 64 MB non-volatile flash
- Serial Ports: 2 (RS-232 and RS-485)
- Switchover Time: Minimum 3.133 ms; maximum one logic scan
- Supported Synchronization Links: Up to two IC695RMX128/228 modules
- Max Program Blocks: 512; maximum 128 KB per block
- Flash Endurance: ≥ 100,000 write/erase cycles
- Current Draw: 1 A at 3.3 V DC; 1.2 A at 5 V DC
- Functional Features:
- Hot-standby redundancy architecture
- Supports local and remote expansion racks
- Compatible with Series 90-30 I/O modules (for staged migration)
- Programming via Ladder, C, Function Block Diagram in Proficy Machine Edition
- Ethernet communications via rack-based Ethernet modules (e.g., IC695ETM001)
- Application Scenarios: Critical process control (power generation, oil & gas), water/wastewater, and any application requiring high availability and rapid failover.
- Performance Parameters:
- Synchronization data transfer up to 2 MB
- Operates in RX3i universal backplanes over PCI (2.2+) bus
- Material and Structural Characteristics:
- Industrial-grade PCB and connectors; conformal coating variants (e.g., -CA) available
- Standard RX3i double-slot module width; front status LEDs
- Working Principle: Two CPUs run identical programs and exchange state data over redundancy modules. Upon detecting a fault, the standby assumes control within one scan.
- Installation Requirements:
- Install in RX3i universal backplane with paired redundancy modules (IC695RMX128/228)
- Both racks must be identically configured; synchronization cabling per GFK-2314
- Usage Notes:
- Configure redundancy in Proficy Machine Edition
- Ensure both CPUs use compatible firmware versions
- Monitor switchover status via system LEDs and diagnostics
