Signal Interface Converter
EKRA-SIC-TCS02

TCS02 converts the differential signal of RS422 physical interface into TTL level binary signal and into complementary (push-pull) output

The converter shall be connected to differential time server outputs on one side and to inputs of protection IEDs, recorders, converters, equipment for various applications on the other side

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