I have purchased one DC Current Expansion board.
I have 2 SS Brewtech FTSS2 heating upgrade kits. Glycol cooling is provided by converted maxi 310 using python pump on maxi to pump glycol through cooling coils in SS brewmaster edition 14g fermenters controlled by brewblox. Glycol flow through coils activated by brewblox switching solenoid valves on or off via SSR connected to Spark V2 by SSRS one wire expansion boards to control cooling on both fermenters.
My query is given I’m not using the stock SS Brewtech cooling pump can I connect both the SS Brewtech heating pads to the one DC Current expansion board and if so do I just need to connect one of the SS Brewtech DC power bricks to the expansion board and I can drive both the heating pads from the one DC expansion board To control heating on both fermenters?
Also I note the DC expansion board has 4 DC terminals but I’m not clear which are input DC and which are output DC. I looked at the photo on the shop and think the left most terminal, if the DC terminals were facing me is the DC input and then there are three outputs, is this correct?
Hope this makes sense!
