Does anyone know if you could use the 16 port relay board the Brewtroller guys sell us interchangible with other platforms?

I'm going to use BCS 462 with several motorized 12v valves and three pumps. Instead of using ssr's for everything I'd like a cheaper option.
 
Hey, Maltose... did you ever get an answer to your question? I've got the same application, and I'm trying to find a relay board that will work with the BCS-462 - hopefully one that covers all 12 (16 will work) of the ON/OFF outputs! I have three pumps, seven valves, and two gas valves to control... that makes TWELVE! ;)

I'm getting wrapped around the axle on the compatibility of the 12V control signals that are put out by the BT vs. 5V/20mA control signals put out by the BCS. I'm leaning towards the BT solution NOT working for us on the BCS side. If the BCS-462 has a regulator, I'm less worried. No regulator, and we're going to fry / fuse those relays!

Good luck!!
 
Yes it will work just fine as long as the BCS can deliver 5v. If you want one I have one that I am not using brand new never used.
 
If the BCS can only do 5V@20mA the BT board is likely to be a problem, as the BT boards are spec'd 12V@30mA. 5V may be enough to trigger the relay, but it's not likely to be too reliable.
The spec's on the relays on most of the BT cards is here:
http://www.mouser.com/ds/2/418/NG_DS_PB_IJ1-208685.pdf
Which specifies the operating(trigger) voltage at 9V, usually relays will trigger lower but it's not likely to be ideal.

Why not go for something cheap & Chinese instead?
Like: http://www.ebay.com/itm/New-5V-8-Ch...956?pt=LH_DefaultDomain_0&hash=item3f17e928d4

I've used these before without problem (different voltages though), I'm sure the quality is not the same as the BT board but food for thought.
 
I purchased one of the eBay Chinese boards, but have yet to test it.

I have 2 of the 4 relay boards and so far they have worked very well for me. Just make sure you put a diode between the relay board and the main board to absorb spike when the relays open and close. I think I used a 1N4007, but I am not sure. Good luck!!!

Well, far from being "cheaper," but nonetheless Chinese, I was looking at this one, since I'm also leaning towards staying on DIN rails inside the control panel:

Has anyone else tried this?

Seems a bit pricey, I would consider using the cheap PCB ones mentioned above and buying some DIN rail adapters to secure them if you like.

Many of these boards already include the diodes as mentioned above.
 
Alright, ya'll convinced me... I just pulled the trigger on two of the following, paying a little more to get them from sent to me free via USPS from San Diego rather than by International Mail from Hong Kong:

I searched pretty long and hard for DIN rail adapters that would come even close to fitting the dimensions of these PCBs, but I found nothing available off-the-shelf. So instead, I'll just drill 4 holes for each and use 4-each 6-32 thread 3/16" standoffs to mount them to the backplane, probably orientating them back-to-back rather than head-to-toe to save a little space.

I'll be doing the same thing using standoffs with a Mini-ITX motherboard from Gigabyte (GA-Z77N-WiFi) that's going inside the control panel to direct-drive the BCS-462, mounting the M/B so that its I/O shield can just snap into the side of the control panel.

DIN is attractive, but it's hard to find the parts needed to use it other than the larger puck style relays, contactors and terminal blocks. Heck, even the BCS-462 will have to directly attached to the backplane. ;)
