The IC695CRU320 is a Redundancy Processor from the PACSystems RX3i product family. This processor is manufactured by GE Fanuc / Emerson that is categorized as Programmable Controllers (PAC).

The IC695CRU320 is especially used in redundant or hot-standby configuration. With this controller configuration, availability is significantly increased. Two (2) controller racks with similar configuration functions as Primary (active) and Secondary (stand-by) rack. When a single rack has failed, primarily due to errors detected by the IC695CRU320 or error of the IC695CRU320 processor itself, active controller duty is automatically transferred to the secondary (stand-by). The secondary rack becomes the primary and the failed rack shift to secondary rack. Additionally, manual switchover is possible.

Controller switchover is performed in Maximum of 1 scan with minimum switchover time of 3.133 msec. It supports up to IC695RMX128/228 synchronization links and capable of transferring up to 2Mbytes of data. With the Celeron M processor with 1GHz processing speed and 64MB user memory, this controller is ideally used in large and complex applications with increased level of criticality. Additionally, up to 512 program blocks may be saved to this processor which each block size may reach up to 128 KB.
