a) active, b) passive (needs additional supply)
PD96 meter has no galvanic separation between measurement input and RS-
485 interface. If serial connection of multiple units is made or serial connection
with other device, without galvanic separation of RS-485 interface, is made
then RS-485 interface separators must to be used certainly (Figure 4.14, 4.15).
If RS-485 interfaces are isolated or not used then the separators are not
necessary.
