LHMI
Communication and
CPU module
1 electrical Ethernet connector for the detached LHMI module (the
connector must not be used for any other purpose)
1 Ethernet connector for communication (selectable electrical or optical
connector)
IRIG-B (external time synchronization) connector
1 fibre-optic connector pair for serial communication (selectable plastic or
glass fibre)
14 binary control inputs
Auxiliary power/binary
output module
48-125 V DC or 100-240 V AC/110-250 V AC
Input contacts for the supervision of the auxiliary supply battery level
3 normally open power output contacts with TCS
3 normally open power output contacts
1 change-over signalling contact
3 additional signalling contacts
1 dedicated internal fault output contact
Analog input module 4 current inputs (1/5 A)
4 voltage inputs (100/110/115/120 V)
1 accurate current input for sensitive earth-fault protection (0.1/0.5 A)
Binary input and
output module
3 normally open power output contacts
1 change-over signalling contact
5 additional signalling contacts
9 binary control inputs
All external wiring, that is CT and VT connectors, BI/O connectors, power supply
connector and communication connections, can be disconnected from the IED
modules with wiring, for example, in service situations. The CT connectors have a
build-in mechanism which automatically short-circuits CT secondaries when the
connector is disconnected from the IED.
