Description
Description
The General Electric IC695CRU320 is a high-performance Redundancy CPU processor module designed for the PACSystems RX3i platform. Engineered for critical industrial applications, this module facilitates hot-standby configurations, significantly increasing system availability. In a redundant setup, the IC695CRU320 manages the synchronization between two controller racks, allowing for an automatic, seamless transfer of control from a primary rack to a secondary rack in the event of a fault. This transition occurs in a maximum of one logic scan, with a minimum switchover time of 3.133 ms.
