Do I need single pole contactors?

Do I need single pole contactors?

Depends if ur using 120 or 240v elements.

 

[Bsquared]

The ones in PJs diagram are two pole, one pole for each of the120 legs to power the 240 elements.

 

[Beeskneesbrew]

So I need 2 pole if I'm using 240v. Such ad these?

I got the 240v/40a ones from Auber instruments

This is a great diagram thanks for all your hard work. What kind of switches are used in this diagram as well as where are theses sourced? Also where can the contactors be sourced with DIN attachment?

Thanks Caleb

Thanks Caleb

The switches are called out in the Legend at the bottom of the drawing page.
Switch #1 is a momentary contact - N/O - push button switch: automationdirect.com - GCX3139 < click it
Switch #2-8 are three position - center off switches: automationdirect.com - GCX3264-120 < click it

Switches 5, 6, & 7 require a second N/O module to have it operate as drawn. None of the switches require the N/C modules. You might be able to negotiate with them to swap the N/C modules for N/O modules. I think it's worth a try anyway.

BTW: The DIN circuit breakers and DIN rails also come from Automation Direct.

Hope this helps you.

What does the n/o contact do on switches 5-8?

 

[P-J]

What does the n/o contact do on switches 5-8?

They provide a seperate path to interlock the system and prevent more than 2 elements from being powered at the same time. They also provide a path to select whether the elements are powered by the BCS system or with manual mode if the BCS system is not available or IF it has failed...

Oh... And the extra n/o modules are for 5-7.

Hope this helps.

Has anyone sourced and cheaper switches? Seems a little spendy.

YOU do what you gotta do. I come up with ideas and plans for the E-Brew community here. You asked which switches I represented in the drawing. I told you. Now what?????

PLEASE give me a break!

 

[bullywee]

i got switches from Pioneer Breaker

 

[Beeskneesbrew]

I don't mean any disrespect towards you...it was a harmless question. I always Like to shop other options.

 

[P-J]

Just do it your way then. I tried to help. - however - I'm done.!

 

[Beeskneesbrew]

You have been a great amount of help!

PJ I know you spend allot of time an d effort on the diagrams you provide and I can say they are a god send. I have one more question for you though. What are the parts numbers on the breakers? I think I have found hem because really the diagram only uses two different kinds a 25amp 240volt and a 15amp 120volt..... also wha would be a good contactor from automation direct and would it be ok to mount that on DIN rails or do they need to be mounted in a manor so they will dissipate heat?

Thanks again
Caleb

The DIN rail breakers are:
automationdirect.com - Single Pole - B Curve - 15A 120V - WMZS1B15
automationdirect.com - Double Pole - B Curve - 25A 240V - WMZS2B25
automationdirect.com - DIN Rail - qty 2 - DN-R35S1-2

Regarding the contactors: I've not been able to find suitable contactors on their site. Auber Instruments has contactors that will do the job just fine. auberins.com - Contactor, 2 pole, 30A, 120V Coil
I'm not sure about DIN rail mounting for them.

Hope this helps you.

I tried looking for a reasonably priced DIN mountable contactor when I was doing my build, but couldn't find one. I highly recommend "Pioneer Breaker". I bought the majority of my parts from them.

PJ you have been a life and money saver. I think through another thread they have located an appropriate coil to replace the ones from Auber but I would like your oppionion on the matter? here is the link... din 120 volt 30A 2 pole

Also I am unsure how to guage the wire on this project would it be best to have a look at the electrical primer provided HERE ?

Thanks again Caleb

Does anyone know if these ssr's will work for PJ's diagram?

.Amazon.com: 25A SSR DC-AC Solid State Relay w/ Heatsink: Everything Else

Thanks,
Matt

 

[bullywee]

they should. good price!

For what? for pumps they will be fine, for a 5500watt heating element I think the consensus is to go with the 40A SSR.

 

[bullywee]

yeah I overlooked that I have 40A for my elements and 25A for my pumps

I first want to let TJ know how everybody on this forum apprecitates how he goes out of his way on diagrahms etc. ....way cool sir! I have a setup that I have been working on for almost 2 years! I call it "Over the Top Brewery" because of the many changes I have made. It is very similar to the op's. The question I have is, and I don't want to come across as a know it all, but why 8 switches on a bcs controlled system, with contactors. I was planning on running an emergency stop that controlled a 50 amp dual pole contactor, of course hooked through a 50 amp gfi in my panel. The bcs would be allowed to monitor temperatures through a 1 amp din mount breaker, even when the contactor is off. I am running din mount double pole breakers through each element. Each element has both legs of 240 going through
ssr's for safety. I thought that the advantage of the BCS was that it was laptop controlled. It seems as though you are "backing up" all of the laptop control with switches and contactors.

 

[gunmetal]

EDIT After "looking" at the diagrahm, I can see that you are trying to make safeguards in the bcs. By not allowing you to run multiple elements and exceeding the 50 amp limit. But if you are using the bcs as it is intended "aka" process states, I guess the programmer could still screw it up.

 

[EarthBound]

lol

 

[Beeskneesbrew]

Does anyone have any experience with these elements, or any opinions?

Or maybe suggestions for 4500w @ 240v?

what's the difference? manufacturer?
