MTL Instruments has announced the launch of the SIL3 rated MTL4850 HART multiplexer for connection to instrument loops performing safety functions up to and including Safety SIL3.
The multiplexer is designed to ensure that there is no effect on the analogue loops to which it is connected; multiple concurrent faults in the components that couple the MTL4850 to the analogue loops would have to be present before the isolation would be compromised. The MTL4850 HART multiplexer does not itself implement a safety function but may be applied alongside measurement and control equipment that is providing a safety function.
Unique design features make it suitable for use in applications where the 4-20 mA instrument loops, to which it is connected, are implementing safety functions up to SIL3 and the techniques used mean that systematic faults can be prevented. The multiplexer provides a common bridge to access HART information for the signal channels that are connected to it. This is particularly important when the multiplexer is associated with signal loops that are feeding a safety shutdown system.
