Upgrades to the San Franciscan controller.

At this point I only have temporary mounting 

to get the placement of the display and the manifold pressure gauge where I want it.

 

The Omron controller is new and I ordered it with RS-232 so it can connect directly to a PC.
Currently it has a platinum RTD and is the bean temp.

The Watlow is used and has RS-485 communications so I will be getting a converter for it
and is a dual loop controller, it will be inlet temp and outlet temp.

I plan on doing some data logging and will produce roasting charts that show bean mass 
absorption rates during the roasting process.

 

The 24v power supply transformer and business end of the controllers, "that's a bunch of terminals
The box is actually to small I wasn't going to put that much stuff in it to begin with 
but ended up with feature creep.

 

2 amp DIN rail mounted Moeller circuit breaker. It was a little tricky to mount the 
DIN rail circuit breaker behind the front panel but it turned out pretty well.

Incredibly this was only a couple of dollars difference in price 
from a panel mounted fuse holder with the fuse.

 

More space for I/O connections.

 

I will be hooking up the inlet and outlet temperature thermocouples soon, 
just need to drill and tap a few holes in just the right places.
