The prime function of SM812, is to provide intelligent supervision of a controller during non-SIL and SIL1-2 operations, and together with a PM867 form a 1oo2 diverse structure for SIL3 applications.

For high availability applications it is possible to have redundant SM812´s that work together with any of the two redundant CPUs. SM812 has a dedicated synchronization link to synchronize active and redundant SM for hot-insert and online upgrade. It is needed during hot-insert and online upgrade situations to copy data between two SM812s in a redundant setup.

The SM812 has a connector with three digital inputs and two digital outputs that can be used for safety-related digital I/O (not process I/O).

Features and benefits:
• MPC866 Microprocessor running at 133 Mhz
• 64 MB RAM
• Provides supervision of the PM857, PM863 and PM867 controller during SIL1-2 operations and together with the PM857, PM863 and PM867 forms a 1oo2 diverse architecture for SIL3 applications
• Over voltage monitoring
• Internal voltage monitoring
• Supports hot swap
• Supports redundancy
• SM Link for synchronization of redundant pair
