The Interconnection Module consists of three sets of twelve 4 mm safety banana jacks and three multiple-contact connectors mounted on the front panel of a full-height EMS module. Three interconnection cables, supplied with the module, are used to connect the banana jacks on the Interconnection Module to the banana jacks on the interconnection panel of the Protective Relaying Control Station, Model 3806, via the multiple contact connectors. This provides an efficient means of interconnecting the electrical power system (EMS system) to the relays installed in the protective relaying control station.
