Wiring of H 7020 redundant with analog output modules F 6217
Analog modules can be connected to the field level by the terminal module H 7020 the same
way as digital modules. In the following example, the analog input modules F 6217 are con-
nected redundantly to each other by the cable plug Z 7127 and the system cable. It is also pos-
sible to connect the I/O modules redundantly via voltage divider or transmitter. For information
about redundant current and voltage connection of the analog output module F 6217 and the
cable plugs, refer to the respective documentation.
