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 DC
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, 7 or 8 current inputs (1/5 A)
4, 3 or 2 voltage inputs (100/110/115/120 V)
With 4 current inputs (1/5 A) also max. 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
RTD input and mA
output module 8 RTD-inputs (sensor/R/V/mA)
4 outputs (mA)
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.
2.4 Local HMI
The LHMI is used for setting, monitoring and controlling the protection relay. The
LHMI comprises the display, buttons, LED indicators and communication port.
