Product Description:
Normally, inductive circuits (e.g. contactor or relay coils) energized by SIMATIC S5 do not require to
be provided with external arc suppressing elements since the necessary suppressing elements are
already integrated on the modules.
It only becomes necessary to provide arc supressing elements for inductive circuits in the following
cases:
• If SIMATIC S5 output circuits can be switched off by additionaly inserted contactors (e.g. relay
contactors for EMERGENCY OFF). In such a case, the integral suppressing elements on the
modules become ineffective.
• If the inductive circuits are not energized by SIMATIC S5.
