This module translates incoming optical signals from SPA, LON, and IEC 60870-5-103 fieldbuses into balanced electrical RS-485 serial data streams. It plugs directly into the integrated 9-pin D-type serial port located on the rear chassis of the host terminal, providing galvanic isolation and noise immunity between the station bus and the internal processing electronics.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\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\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eFinland\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.15 kg\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 (W x H x D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\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\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePowered from the host device (5 V DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface Type\u003c\/td\u003e\n\u003ctd\u003eRS-485 electrical protocol conversion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003e9-pin D-type male plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Topologies\u003c\/td\u003e\n\u003ctd\u003eLoop and Star configurations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Transfer Rate\u003c\/td\u003e\n\u003ctd\u003eUp to 1.25 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity and Network Integration\u003c\/h3\u003e\n\u003cp\u003eThe RER 103 links to host hardware architectures via a direct-mating 9-pin interface to ensure stable backplane bus communication velocity baselines up to 1.25 Mbps. It bridges localized hardware blocks to external Profinet or EtherNet\/IP deterministic networks via protocol mapping proxies, sustaining fast transmission rings in both loop and star network topologies. The module maintains native firmware flash compatibility with the RE500 processor core, ensuring correct parity verification and line termination constraints are enforced across all connected communication channels during I\/O density scaling procedures.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":47582980931774,"sku":"RER 103","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-05-27_10-21-41.png?v=1779848638","url":"https:\/\/www.autooiltech.com\/products\/abb-rer103-interface-unit","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
