SIL 3 Smart Safety Relays

Switching of Safety-Related circuits demands the use of specific SIL certified Relay Output modules, capable of delivering the highest grade of availability and functional safety. 
These units are so much more than just a relay; they not only perform the desired safety function, but also provide full Load & Line Internal Diagnostics: load voltage and current, load resistance (patented), leakage from load to earth, coil integrity and internal faults. Moreover, MODBUS communication allows the units to be remotely interrogated and configured.
Hardware is SIL 3 certified, while diagnostic functions are now also SIL 2 certified by TUV: they remain two independent features, which can be used separately or together.

For installation in Zone 2 / Div. 2 Hazardous location. All models are ATEX, IECEx and SIL certified.
