The MTL4850 HART multiplexer provides a simple interface between smart devices in the field, control/safety systems and HART® instrument management software running on a PC.  

The system is based on 32-channel modularity to provide a compact, easily configurable and expandable system. Using a standard RS485 serial link, up to 2016 individual HART devices can be connected to a single network.

For the optimum solution, the modules mount directly to either a range of generic or customised connection units/backplanes. 

The MTL4850 is certified for the use with safety related subsystems to IEC 61508, and is the first choice of HART multiplexer for these applications. It can be connected to signal loops that are part of safety instrumented functions up to SIL3.
With the fixed modularity of 32 channels, the speed of scanning field devices and responsiveness to PC software requests is optimised when compared to master/slave configurations. 

The MTL4854 mounts on the same range of backplane as the MTL4850 but includes four HART modems that enable simultaneous communications with connected field devices to be carried out.
The primary application for this is to enable monitoring of other channels to continue while one channel is being used for valve positioner diagnostics.
