Isolation—protecting your system
Designing your plant with good clean
earth systems is not always possible. Poor
ground conductivity, large process areas and
heavy electrical machinery, all contribute to
increased noise. This noise is induced or
conducted into adjacent wiring, which in turn
degrades the quality of the signals passing
through the cables. Without isolation this
noise is superimposed on the process signal
causing a loss of accuracy, poor control and
possibly failures or false trips.
Many control systems, PLCs and safety
systems do not have full isolation between
channels. In compact well defined plant
layouts this is acceptable, but these are
not always guaranteed. To avoid interference
between channels, isolation is the solution.
The MTL4600 series isolators offer reduced
risk and greater protection to the system,
with all the advantages of a common design
approach for both IS and non-IS signals.

System Solutions
Building on the base of the MTL4500
series solutions, the MTL4600 offers a high
level of signal isolation for installations where
multiple loops on a common connection are
not desirable.
Signal isolation provides excellent
protection against surges, common faults
and noisy environments. It also eliminates
the risk of earth loops between different
areas of the plant, which, if not isolated, can
cause significant errors or failures under fault
conditions.
MTL4600 isolators are fully compatible with
all existing backplanes used with MTL4500
series and many control systems. The form
factor and signal types offer the user a
common approach for both IS and non-IS
signals.
The backplane mounting MTL4600 Series
is designed with system vendors in mind
for "project-focussed" applications such as
Distributed Control System (DCS), Emergency
Shutdown Systems (ESD) and Fire and Gas
monitoring (F&G).
