Electrical configuration
Galvanic isolation
In the redundant System S7-1500R/H, there is electrical isolation between:
● The communication interfaces (PROFINET) of the R-CPU and all other circuit
components
● The communication interfaces (PROFINET) of the H-CPU and all other circuit
components
High-frequency interference currents are conducted and electrostatic charges are avoided
through integrated RC combinations or integrated capacitors.
