Finder Master Plus - relay interface module with a fuse module
It is known, that it is ideal to protect every controlled peripherial separately. Rail-mounted relay interface module Finder Master Plus 39.3x integrates function of a switching and protective element into one component.
In praxis, devices controlled by PLC (Programmable Logic Controller) are
usually connected in groups, protected by some of the standard circuit breakers,
while this common circuit breaker is rated to a value sufficient for overall
current. Number of circuit breakers is reduced from economical reasons as well
as increased complexity of a distribution box. To one circuit breaker are thus
usually connected more devices controlled by an appropriate interface (EMR or
SSR module). Possible overcurrent of a blocked AC valve or a motor can often
stay unrecognized, as a circuit breaker is rated to a higher current. Moreover,
if it will show after some time, that some of peripherials are necessary to be
protected separatelly, a problem with a lack of space in a distribution box may
occur.
These drawbacks are eliminated in a module Finder Master Plus, which can be
equipped with a fuse module for a standard 20x5mm fuse. Fuse module is delivered
separately and the internal electrical link allows relay interface module to be
used also without a fuse module. Condition of the fuse is easily visible through
a window. At width of a relay module only 6,2 mm, it is an interface with an
individual protection, occupying only a minimum space on the rail.
Interconnections in a distribution box can be further simplified and be more
transparent thanks to a possibility to use interconnection jumper links. Finder
Master Plus 39.3x are available in several versions, EMR or SSR, at the type
39.3x.3 also with a leakage current suppression.
