MTL4851 & MTL4852 HART multiplexers, MTL4850 SIL3 multiplexer, MTL4854 Multi-modem multiplexer.
The MTL4851 and MTL4852 HART connection system provides a simple interface between smart devices in the field, control systems and HART
instrument management software run on a pc.
The system is based on 16-channel modularity to provide a compact, easily configurable and expandable system. Using a standard RS485 serial
link up to 7936 HART devices can be connected on a single network. For the optimum solution, choose from a range of general purpose and IS termination boards. For maximum flexibility the HMM64 HART backplane locates an MTL4851 master communications module and up to three MTL4852 secondary interface modules, with each module connecting to 16 field devices. General purpose HART connection units and IS backplanes are available fitted with an cable interface connection to the HMM64. This system can be extended with further HMS64 HART backplanes linked to the master, each carrying up to four MTL4852 secondary interface modules.
The MTL4851 and MTL4852 modules can also be located on HTPSC16x termination boards for general purpose applications. HART loops are simply wired through these HART Termination Panels and may be grounded or floating circuits. The HTP boards offer a compact and costeffective solution for general applications. CPH-SC16x backplanes are ideal for signal loops requiring intrinsic safety (IS) protection, combining multiplexer and IS isolator mounting. This offers considerable simplification in wiring when compared to DIN-rail based solutions.
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.
