JB2X-PDB/JB2X-DIN series junction box is an ideal solution for connecting more than two obstruction lights’ power and alarm wires in parallel.
This series junction box’s enclosure is powder painted aluminum alloy. With nickel-plated brass cable glands and an o-ring silicone gasket, the junction box’s protection grade is IP65.
JB2X-PDB contains multiple 1-IN and multiple-OUT power distribution terminal blocks, which allow users to connect multiple obstruction lights in parallel into one power input and one alarm input. Same functionalities as JB2X-PDB, JB2X-DIN contains multiple DIN-rail terminals and pre-plugged jumpers to combine multiple power and alarm outputs in parallel into one. In a typical FAA A1 system with one F864 medium intensity beacon and two OL32 single sidelights, if users only reserve one dry alarm port for obstruction lighting system, JM2X-PDB/DIN will be used for connecting the three outputs’ power wires in parallel into one power input and connecting the three outputs’ alarm wires in parallel into one alarm input.
