    I am looking to see if there is any interest in a product supporting C-Bus, especially new installs.
    As new C-Bus Output units (dimmers, relays, etc) no longer have support for a Software Burden, and the use of the hardware burden is usually met with complaints about taking up a port in the Dimmer or Relay along with just not having a suitable solution for breaking out of the Switchboard for the field bus, and last of all, once the cover is on no visibility of if there is a hardware burden installed and where is it installed.

    I propose to address all of these issues with the following concept device. In Din Rail (2 Module 36mm) you get 2 x C-Bus RJ45 Connections at the bottom for connecting to C-Bus Dinrail Products in the Switchboard, PLus 2 x Phoenix Connections at the top for breaking out to the field bus, Plus 1 RJ45 Connection for C-Bus coming out the front providing you bus access without having to take the cover of the switchboard, and a switchable C-Bus burden (recessed into the top cover) . Also, plan to allow space for the label on top so you can capture details of where the field bus runs to etc.

    If I can drum up some interest for these, I am willing to make a few, (using quality parts, proper production built PCB's and No 3D Printed crap) if making 10 or less pcs, the Price would be $73.00 each (inc GST) + Shipping, with greater volume the price comes down, I estimate at 50+ pcs, price range of $40-$50, without compromising the Quality of components, there are good break points at 100pcs for components like the RJ45 Sockets (3 per unit) and Phoenix Connectors (2 per unit)

    If anybody thinks these would be a good value and is interested, please express your interest here or PM me.
    If you think it needs something else included, let me know.
    Please do not propose 1 module 18mm, I know it would be good to be smaller, but honestly, the RJ45 Sockets are too big ~16mm wide, and I would not suggest them being on their side, vertically, as this may lead to termination issues over time (prefer to let gravity work for it not against it)

    The case will have a Clear Cover, protecting the front RJ45 and the Burden Switch (so you need to open the cover to plug in a PCI or change the Burden setting.

    Still think itsa nice idea to see where the Burden is and if it is set or not set

    I like the idea, however I am cheap and a burden costs a dollar to make and we can put it at the first wired terminal. if I was to make one, a simple impendence test will tell you if you need one A network burden should only be used to adjust the network impedance to between 400Ω and 1.5 kΩ
