Engineered for critical industrial infrastructure and process applications requiring zero-downtime operation, this redundant CPU features built-in high-availability Hot Standby (HSBY) dual-controller synchronization. Operating on a 24V DC backplane power supply, the unit provides \u003cstrong\u003e8 MB of internal program memory\u003c\/strong\u003e, \u003cstrong\u003e1024 KB of data memory\u003c\/strong\u003e, and supports up to \u003cstrong\u003e2048 digital I\/O and 512 analog I\/O channels\u003c\/strong\u003e. Equipped with integrated Ethernet backplane switching and redundant power supply compatibility, the controller delivers maximum reliability and fast execution cycles (0.12 ms for Boolean tasks). The module features an approximate net weight of \u003cstrong\u003e0.85 kg (1.87 lbs)\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable border=\"1\" style=\"width: 100%;
