3.5.6 Inductive Load Interference Suppression
The outputs in the devices described in this manual feature an integrated surge protection circuit against
interference voltage that arises when switching inductive devices.
The varistor ensures rapid dissipation of the energy stored in the magnetic field of the inductive load.
The high voltages which occur when switching off inductive loads produce strong fields in the wiring.
These fields can in turn trigger faults in adjacent circuits or devices. For this reason, it is recommended
that an additional inductive load circuit be provided where large distances exist between the module
output and the load, or where high inductive loads occur for other reasons. As a result, the voltage peak
produced by the inductive load is short-circuited directly at source.
Murrelektronik GmbH offers a wide range of interference suppression products for
this purpose.
3.5.7 Limits and what can still be done...
System configurations are conceivable where the interference emission and noise immunity requirements
can only be met by implementing additional resources or not at all, as the EMC in the system is also
dependent on the products of other manufacturers.
Line filters are suitable for reducing power related interference.
Various manufacturers offer fiber-optic converters. Data transmission through fiber-optic cables is
less sensitive to EMC interference. This does not, however, apply to the electronics required for the
conversion. As such, fiber optics cannot solve all EMC-related problems.
Should you have any further questions regarding EMC, or require advice on fulfilling
the EMC directives in your installation, please contact our accredited test center.
