The General Electric IC695CRU320 is a high-performance redundancy processor designed for the PACSystems RX3i automation platform. Engineered for mission-critical applications, this CPU module enables hot-standby configurations, significantly increasing system availability by allowing a secondary controller to assume control automatically in the event of a primary rack failure.
Features
Redundancy Support: Designed for high-availability setups with automatic switchover capabilities.
High-Speed Processing: Equipped with a 1 GHz Celeron M microprocessor.
Memory Capacity: Features 64 MB of battery-backed RAM for data integrity and 64 MB of non-volatile flash user memory for permanent storage.
Switchover Performance: Rapid switchover time with a maximum of one logic scan (minimum 3.133 msec).
Communication: Integrated with two serial ports supporting RS232 and RS485 standards.
Advanced Diagnostics: Includes dedicated System Fault (Sys Flt) and I/O Force LEDs for real-time status monitoring.

Battery: Requires an external high-capacity battery (IC693ACC302) to maintain the battery-backed RAM during power cycles.
FAQ
What is the primary function of the IC695CRU320?
It acts as a redundancy processor in a hot-standby configuration, allowing a backup controller to take over immediately if the primary unit fails, thereby minimizing downtime in critical processes.
Does this module include the required battery?
No, the IC695CRU320 requires an external IC693ACC302 battery for memory backup, which is not included unless explicitly stated in your order.
Can I perform a manual switchover?
Yes, the system supports both automatic and manual switchover between the primary and secondary controller racks.
