A mountable wiring adapter for extending continuity of a communication bus while providing wiring terminals to access the communication bus

A method for mounting a plurality of building management system (BMS) components on a DIN rail, the method comprising:

• mounting a first BMS component on the DIN rail, the first BMS component including a housing and plurality of spring contact pairs, wherein each of the plurality of spring contact pairs are electrically connected together and are positioned on two opposing sides of the housing, wherein each of the spring contacts is configured to electrically and mechanically couple to a corresponding spring contact of an adjacently mounted BMS component on the DIN rail;
• mounting a first wiring adaptor adjacent to the first BMS component on the DIN rail, with a first side of the first wiring adaptor adjacent the first BMS component, the first wiring adaptor including a housing and plurality of spring contact pairs, wherein each of the plurality of spring contact pairs of the first wiring adaptor are electrically connected together and are positioned on two opposing sides of the housing of the first wiring adaptor, wherein each of the spring contacts on the first side of the first wiring adaptor is configured to electrically and mechanically couple to a corresponding spring contact of the adjacently mounted first BMS component;
• and
• connecting one or more first wires to one or more wiring terminals of the first wiring adaptor, wherein each of the one or more wiring terminals of the first wiring adaptor are electrically coupled to a corresponding spring contact pair of the first wiring adaptor.

A wiring adaptor configured for use with neighboring electronic devices mounted on a DIN rail in order to maintain a communication bus through the wiring adaptor and provide wiring terminals to tap the communication bus, the wiring adaptor comprising:

• a housing configured to be mountable next to an electronic device on a DIN rail;
• a plurality of power passthroughs extending through the housing and including spring contacts disposed on two opposing sides of the housing such that the spring contacts are configured to electrically coupled with spring contacts disposed on one or more sides of a neighboring electronic device in order to maintain power between the wiring adaptor and the neighboring electronic device;
• and
• a plurality of communication passthroughs extending through the housing and including spring contacts disposed on the two opposing sides of the housing such that the spring contacts are configured to electrically couple with spring contacts disposed on one or more sides of the neighboring electronic device in order to maintain the communication bus between the wiring adaptor and the neighboring electronic device.
