S4SC-1000 (*) is an off-shelf product from Intecs Solutions ready to be used for specific on-board applications.

The S4SC-1000 provides all the basic functionalities required for the implementation of Safety Critical SIL4 solutions, including an intrinsically safe «voting» feature that can also be used for validating «vital» data from two separate sources.

S4SC-1000 is built on 2oo2 (2-out-of-2) architecture certified SIL-4 and conforms to the RFI IS402 standard.

General characteristics

Safety: Safety Integrity Level (SIL) 4, based on the CENELEC EN 50129 standard. The requirement is met thanks to the implementation of a 2oo2 architecture.

Reliability: MTBF> 10 years thanks to the use of two units in cold redundancy connected by a special 'switch'.

Protection against deadlock guaranteed through the use of a 'watchdog' mechanism managed at the software level.
