OONO16 Amp 2x12 Position Terminal Block Distribution Module for AC DC

Well constructed unit. This is providing the ground plane that my CNC Control was missing.

Works well.

I have LOTs of illuminated structures on my HO scale layout. Many use older incandescent miniature lights, some use newer LEDs in integrated resistors, and some tiny LEDs than cannot handle more than 3 VDC. I have many old power packs that I can use for accessory lightening and I run 16 VAC to a terminal block, 12 VDC to a terminal block and a 3 VDC battery pack to another terminal block. Simply run the desired lead to the power that it needs and screw the wires in. Easy, neat, and much less likely to use the wrong kind of power and burn out an LED. They are also useful wiring AC common to switches and anywhere else where multiple connections of a common voltage are needed. They just make wiring a little easier.

I am using many of these to wire my O gauge train lighting accessories. I guess I have used 25 to 30 of them on my 40 x 45 layout. They made the wiring process very fast and easy.

Seems constructed really well. The downside is that the underside isn’t insulated and no pictures are of the underside. You will have to mount it using the insulators to raise it. I can’t use it for my project because of this.

Not easy to connect wires to this unit. Being Patient helps

I'm someone who hunts for the best value, no point in paying for extra if you don't. I've compared this with a 1-2 dollar cheaper version. Comes in a box over a anti static bag. The labeling is better and this sits lower (could be pro or con). PCB is nicely labeled throughout and solder joints are shiny (better solder used). While there is nothing wrong with the cheaper version, this version is worth the extra 2 bucks.

Best feeder block for model railroaders around. Saw t on YouTube and just had to get some.
