This multiplexer is rated up to SIL 3

The SIL3-rated MTL 4850 Hart Multiplexer  is suitable for connecting to instrument loops performing safety functions, and is designed to ensure that there is no effect on the analog loops to which it is connected. Multiple concurrent faults in the components that couple the MTL4850 to the analog loops would have to be present before the isolation would be compromised. The multiplexer provides a common bridge to access HART information for the signal channels that are connected to it; this is important when the multiplexer is associated with signal loops that are feeding a safety shutdown system. — MTL Instruments Group Ltd., Luton, U.K.
