• Mount directly to a range of customised connection units

• MTL4850 designed for use with SIL3 loops (non interfering)

• MTL4854 designed for use in partial-stroke test valve

positioner applications

• Connect over 2000 loops on one RS485 network

• Auto baud rate detection

• LED indication for fault diagnosis

• Isolated Power Supply

• Firmware upgradeable

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 sub

systems 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.
