Connector for Protection Systems ABB RER103 MM Bus

Description

TheABB RER 103module is a versatilebus connection interfacethat facilitates communication betweenprotection and control devicesusing various industrial protocols. It convertsoptical signalsfromSPA,LON®, orIEC 60870-5-103buses intoelectrical RS-485signals, which are compatible withRE500 seriesequipment. The module is designed to work inlooporstar topologies, offering flexibility in both system design and expansion. With acompact form factorandplug-in design, theRER 103ensures easy installation into host devices viaD-sub connectors. Additionally, it features aselectable line idle state, allowing users to configure whether the optical signal remainslitordarkwhen the line is idle.
