Signal Interface Converter
EKRA-SIC-SCTF01

SCTF01 converts the input TTL signal into optical signal, as well as into differential signal of RS422 physical interface

The converter shall be connected to TTL output of time server from one side, and to optical or wired interfaces of converters and IEDs from the other side

The converter performs no additional logical processing of the input TTL signal, thus, the waveform of the output signal always matches the waveform of the input signal

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