ABB RER 103 Bus Connection Module
Functional Description
The bus connection module RER103 acts as an interfacing unit between an RE_ 500 device and the fibre-
optic LON or SPA bus. The bus connection module converts incoming optical signals from the LON/SPA bus
to electrical RS 485 signals for the RE_ 500 devices and vice versa.
The module is plugged into the D-type subminiature connector on the rear plate of the host device. It can be
used together with any RE_ 500 device provided with a 9-pin D-type connector. The bus connection module
is powered from the D-type connector of the host device. RER103 contains a Service Pin for LON nodes.
