Struggling to wire all the connection under your layout? Use the Hydra Bus Bar to make things easier!

This is a bus bar with 16 output terminals that works on either DC or DCC. A unique isolate function allows you to switch off sections to help with fault finding in the event of a short.

Red and green LED's indicate the polarity of the incoming supply or the presence of a DCC signal.

In DC mode the bus bar with simply allow multiple connections to the same power supply. The isolate function will switch off everything connected to that board. There is also a pass-through connector to go to the next board in the chain.

In DCC mode simply connect your wires from your controller to the power in terminals and all your dropper wires from your track to any of the 16 screw terminals. The pass-through terminals allow multiple boards to be connected in a chain.

Have you seen our new pre-wired rail joiners? They are perfect for use with the Hydra board!

Note for the isolate function to work correctly in DCC mode it's important that you separate your track into isolated sections and power each section via a single bus bar.

Full instructions with example wiring diagrams for all uses is included.

The maximum current per board is 5A.
