Break out Box for Neptune Kit

59 reviews
$ 29.99

A very easy beginner soldering project.  This kit comes with all the parts you need to assemble the break out box and takes about 15 minutes to assemble. 

This robust terminal box allows up to six digital devices to be easily connected to the I/O port of the Neptune Apex aquarium controller.  Unlike similar input boxes from Neptune, ours features heavy duty spring terminals, with a separate common terminal for each input.  This is very important, as a shared screw terminal becomes very unwieldy when you try to shove six wires into one small hole.  With ours, just push each in by pressing on the tab, and releasing the tension to lock it in place.

Breakout box

Easy to assemble. And I love not trying to attach six wires to 1 screw. Love Avast ❤️

This is an absolute must have and so much easier to use then the Neptune breakout box. Very simple and straightforward.

Superb Kit, one addition may be nice.

Kit was easy to assemble, having a level 3 soldering training ease of connections are a breeze. Might be handy to a simple paper with a exploded view of wiring color diagram, while the youtube video is very clear. A paper insert would take it over the top.

Love this product

I love this product! It was very easy to put together and very well constructed. I’m considering buying another one for my other reef tank as this breakout box is way better built than the Neptune version.

What the Apex breakout box should have been

This is a great breakout box. Works perfectly. Having the ground connector separate for each switch makes life so much easier. They sell this in two versions, one is fully built and the cost is close to the same as the Apex box. The other (the one I bought) is about half the price but requires assembly and a bit of soldering. No instructions were included so you have to look up a how to video on Youtube. Once you have the video, assembly is easy and the soldering is very basic but you do need soldering supplies on hand. It took me about 30 minute to assemble and there were not any issues. This unit works flawlessly with the Apex controller.
