Mounted directly to the host device's rear panel via a 9-pin D-type connector, it performs bidirectional optical-to-electrical signal conversion between RS-485 interfaces and SPA, LON, or IEC 60870-5-103 communication buses.\u003c\/p\u003e\n\u003ch3\u003eSignal Conversion and Optical Interface\u003c\/h3\u003e\n\u003cp\u003eThe module converts serial communication data between RS-485 electrical signals and fiber-optic signals at transmission rates up to 1.25 Mbps. Fiber-optic media isolation provides high immunity to electromagnetic interference and electrical noise in substation environments. The unit is available in hardware configurations supporting both plastic and glass fiber optic cables using ST-type optical connectors.\u003c\/p\u003e\n\u003ch3\u003ePower Supply and Physical Integration\u003c\/h3\u003e\n\u003cp\u003eOperating without an external power source, the module draws its 5 V DC auxiliary power supply directly from the host RE_500 protection relay through the D-type interface connector, with a maximum power consumption of approximately 0.4 W. Its compact plastic housing measures 35 mm $\\times$ 73 mm $\\times$ 20 mm and connects directly to the rear panel of compatible host units.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eRER 103\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eBus Connection Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible System\u003c\/td\u003e\n\u003ctd\u003eABB RE_500 Series (REF, REM, RET)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocols\u003c\/td\u003e\n\u003ctd\u003eSPA, LON, IEC 60870-5-103\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrical Interface\u003c\/td\u003e\n\u003ctd\u003eRS-485\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHost Connection\u003c\/td\u003e\n\u003ctd\u003e9-pin D-type connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Connector Type\u003c\/td\u003e\n\u003ctd\u003eST connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Conversion\u003c\/td\u003e\n\u003ctd\u003eBidirectional optical-to-electrical \/ electrical-to-optical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Power Supply\u003c\/td\u003e\n\u003ctd\u003e5 V DC (drawn directly from host device)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e0.4 W maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Data Rate\u003c\/td\u003e\n\u003ctd\u003e1.25 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-10 deg C to +55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e35 mm x 73 mm x 20 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How is the RER 103 module powered?
