SSR vs PAC controllers

Could someone explain the difference between these two style of controllers? Just wondering if either have any advantages.

As far as I know PACs are micro computers for automation controls, don't see any use in dis tilling unless your building a still like Odin's iStill

A SSR, or Solid State Relay, is just a simple On-Off switch which uses some type of control circuit... A PAC, or Programmable Automation Controller, is a control circuit which could be used with specific types of SSR's and other devices... For heating a still you only need a simple SSR controller...
There are no real advantages to making the heating process more complicated than it needs to be unless you are a gadget freak or just like playing with electronics and over-complicating every task you can... Everything I design and build falls more in line with the KISS concept rather than a bunch of bells and whistles... This stems back to when I was growing up and building projects in the basement or in my uncles work shed on his farm... Heck, every motorized vehicle I built, whether three wheeler or go cart, never even had brakes installed... I was all Go and no Whoa...!!! Even my electronics circuits have all been on the simpler side... I'm a minimalist at heart, I guess...

Thanks guys. I'm not electronic guru so that's why I asked. I'm not one to try to make things more complicated than they need be. Eventually I want to convert to electric. The last year I have gotten lucky and had a couple of 100lb cylinders of LP given to me. I've gone through one so far and now that I'm working on the second one I realize my supply is coming to an end and I don't want to spend the money on gas anymore. Let alone moving those tanks around us a pain in the ass and during the stilling process its loud!

I use a SSR (Solid State Relay) in conjunction with a PAC (Phase Angle Controller) to provide very precise control of the amount of heat being applied to my boiler/cooker.

The proper amount of power input, or trying to control vapor temperature - which isn't what you want...???

I use an SCR, works pretty good never had any problems. Just ordered another one (10000 watt 240 v) for my beer set up.

There is no mention of temperature in my post.

I assume that your element controller uses the phase angle control unit to supply variable voltage to a SSR that is controlled by low voltage.

Read the datasheet. That makes a very elegant solution. Thanks for sharing.

Soggy Bottom Boy,
You are correct. The SSR is controlled by a PID that I can use to monitor temperatures. I originally built my panel for brewing beer where one needs to control temperatures. It is a bit of over kill (Ok, ok. I'm a tinkerer and a gadget freak) but as Skow69 has pointed out, it is a rather elegant solution.
Skow69,
You're welcome.
