Operation Functionality

Relay functions

REF601/REJ601 offers pre-configured functionality which facilitates easy and fast
commissioning of switchgear. To emphasize the simplicity of relay's usage, only
application specific parameters needs to set within the relay's intended area of
application.
The settings can be changed via LHMI (Local Human-Machine Interface) or
through optional communication interface MODBUS master with setting
capability.
The relay offers protection, control, measurement and condition monitoring
functionality.
