X000 Optional
communication
module
See the technical manual for details about different types of
communication modules.
1) The 0.2/1 A input is normally used in applications requiring sensitive earth-fault protection and featuring
core-balance current transformers.
The rated input levels are selected in the software of the protection relay for phase current
and ground current. The binary input thresholds 18...176 V DC are selected by adjusting
the protection relay's parameter settings.
The optional BIO module can be added in the protection relay to all
standard configurations.
The connection diagrams of different hardware modules are presented in this manual.
See the installation manual for more information about the case and the
plug-in unit.
