SIL Rating
The minimum Sil rating of the 88XX according IEC61508 is SIL1 which means a minimum risk reduction factor of
100.000-1.000.000 per hour at continuous operation. The 88XX can be equipped with a secondary detection circuit
with its own relay output to get a higher Sil rating. This circuit is, besides power-supply, completely independent of
the main circuitry. The extra relay output (AUX-2) but can be wired separately to the terminal safety automation
system to create a the higher probability of dangerous failure per hour.
