Electrical isolation

SM 335 contains a variety of different analog elements. The analog outputs are electrically
isolated to the backplane bus of SIMATIC S7-300. All outputs are connected to the common
potential M
potential M
The analog outputs are electrically isolated to each other and to the backplane bus of
SIMATIC S7-300.
The input for internal counter IZ is electrically isolated to all other analog components and to
the backplane bus of SIMATIC S7-300.
