Signal Interface Converter
EKRA-SIC-TCF01

TCF01 converts the differential signal of RS422 physical interface or TTL signal into optical signal

The converter shall be connected to RS422 output of SV02 time servers from one side, and to optical interface of converters and IEDs on the other side

The converter is used in combination with SV series time server designed for use in time synchronization systems for control & automation systems for stations and substations

TCF01 has metal enclosure and shall be mounted on the DIN-rail
