Finder Master Plus - relay interface module with a fuse module

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.
