Nice looking build so far, looks like you are one of the few competent panel builders that I have seen. It looks you have a couple solenoid air valves, what are they planned for, air actuated valves like Claudius has on his rig?.
This is the easy part, hardware build, the hard part is the HMI programming with automatic sequencing and control. At least you have HMI software support which makes the task easier than coding your own from scratch which can take a significant amount of time.

The SV's Are For Inlet, Drain and C.I.P.
Thank's. I Like Laying a Panel Out Like This, Later On It Takes The
Troubleshooting Pain Away.
I Could Not Imagine The Time Coding From Scratch, Even w/HMI & PLC
Software Takes Alot Of Time From Scratch.

A suggestion, lose the automotive ring lugs on the higher current connections and use heavier gauge copper compression lug by T&B or the screw tightened Blackburn models. This is the single greatest cause of SSR problems out there, yes they will connect the wire, but they have to be crimped perfectly and make a perfect connection, which is not likely with most installations. The heavier lugs will carry more current without heating up and causing the SSR to go into thermal lockup, and can be insulated with heat shrink tube. A cheap thermal tattle tail is melt a drop of crayon on the screw head, if it melts and runs during operation you have a thermal problem.
The HMI application for the brew system was built to merge the recipe and control functions into one package, a process that lasted over a year in coding and testing. The brewing system is much more complicated than any other home brewing system, and takes more control and logic to operate safely unattended.

Excellent Suggestions, Don't Like Crimping, All Lugs Are Soldered Here and
All Stripped Wire Ends Are Soldered As Well
Will Locate & Install, Thank's Kladue

It is a pain in the butt and I only programmed the application part.
The program I purchased from Automation Direct to work with there touch panel.
I have always been impressed with your talent.
