Signal Interface Converter
EKRA-SIC-FCS02

FCS02 converts the digital optical FOL signal into electrical differential PPS/IRIGB signal of RS422 interface, and also retransmits it to its optical output, acting as an amplifier-repeater of the FOL signal

The converter shall be connected to fiber-optic line (FOL) from one side and to protection IEDs, recorders, converters, equipment for various applications from the other side

FCS02 devices shall be mounted on the DIN-rail

Features
Specifications

Multitasking

The device converts the optical signal into differential signal of RS422 physical interface and into complementary (push-pull) output. “Out” output supports signal inversion

High reliability

The device is designed for continuous operation

Compatibility

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

Galvanic isolation

The converter provides galvanic isolation from communication line, as well as current overload protection at "Out" output
