BCS Fermenter Controller Wiring Diagram

beermaestro · Mar 21, 2018

I am looking to build a fermenter controller using a BCS 460. I have a wiring diagram that I have modified to suit my needs/wants and am looking for some feedback to see if I have missed something or have anything wired incorrectly. Feedback is welcomed and greatly appreciated. My goal is to control 3 fermenters and a heater with this controller. I would like, based off of temperature, to control all three of my fermenters and a seperate heated cooler full of water. I would use the temperature portion to turn on and off pumps and an aquarium heater housed in a cooler to maintain temperatures. The front of my panel will house 4 led PID style displays so I can easily glance and see what my set temps and actual temps are of my vessels. Ultimately I will also incorporate a glycol chiller in this process during summer months. In which case I would just swap the pumps from the heated cooler of water to my glycol chiller reservoir. Thanks in advance for any feedback.

Well I finally finished my control panel for fermentation. I still have a bit of wire management to do to clean things up a bit. I have my wireless router ordered as well to plug in for wireless access. Overall though, came out just how I wanted it to.

as long as the relay board is triggered on a high input, (and you actually wire the thermometer panel jacks) you look good to go.

Yes the relay board is wired off of the outputs 0-3 of the BCS which based on temperatures should switch power to the 120v outlets which will turn my pumps on and off. Just received my wireless router in mail today so now I have some programming to do. Excited to see it in action

to be clear, there are two kinds of relay boards, those that energize the relay when the input is grounded, and those that energize the relay when voltage is applied. The BCS requires the latter of the two. I just could not see from the picture which you had.

You are correct, I made sure I ordered the right one based off discussions from ECC forum boards. Everything seems to be functioning properly so far, my relay board is providing power to my outlets based on the bcs outputs. Now just need to purchase my glycol chiller...... so I can start using this thing.
