Yep, when they should be using a Banjo burner if running propane... Never understood some of Regan's logic

My probes are 6" long. They stick into the fitting area right into the flow of the liquid. Not sure where the 2" reference came from.

Default I just laid out some cash

Purchases
6 Ball valves can be manually operated (12V ) https://www.oscsys.com/store/product/291
3 March SS Center Inlet Pump (120V)
3 Gas Solenoid Gas Valves (12V)
3 "Honeywell Glowfly Hot Surface Igniter". (120V) Ebay Model number Q32001004
1 BCS-462 http://brewershardware.com
1 BCS-DIGI 16 Expansion Board; non-powered
1 8 channel PIC Relay 12V

I am looking for a 12V power supply for my 9- 12V D/C Valves.
Any ideas?

The power supply you get really depends on how much current you need. I used 12V ball valves for the liquid side, but I used 120V valves for the gas solenoids because the 12V ones needed a lot of current. 12V solenoids need something like 800 mA, so for 3 valves, you need 2.4 amps. That's a lot of 12V current. Instead, use the 120V gas valves and trigger them with an SSR just like the pumps. They will only need a couple of milliamps to trigger. The 12V ball valves only use something like 40 mA to operate. A single 1 amp 12V power supply can run all the ball valves and relay board, with plenty of current to spare.

I used 120v for my gas also and the 12vdc ball valves for the liguid side (7 total). The valves only use current when they are opening or closing so its more efficient and as a result the power supply can be smaller (mine was the 5A one). Worst case scenerio is to add up how much current they all will use at once and use a power supply that produces that much current at least. I got my power supplies from ebay (china) for only 10 bucks a piece. Make sure you take cover off them and check for the 120 volt jumper settings on them mine came with the jumper set to 220. They are working great on my rig. the sellers name is "gadgetextreme" just look his store up on ebay.

Jon, or anyone else for that matter, I'm not grasping the relay board thing. The BCS has a 5V output and the ball valves require 12V. How are you getting 12V to the valves from the BCS?

The coil of a relay does not have to require the same voltage or amperage of the load that it is switching. That's the biggest advantage of a relay.

The relay board pictured runs on 5VDC, the coils are 5VDC and we are switching 5VDC, 12VDC, 24VAC and 120VAC

The 5V output of the BCS does not power anything - it is merely a 5V trigger. Think of your 120V SSR's... You wire up a pump to them and when the BCS activates the output to the SSR, it just triggers it to switch the 120V current. With your 12V setup, you have valves and relays that need 12V to operate. The BCS again just triggers the relay, but the relay itself and the valves use 12V.

Some people mistakenly think that if they use 5V relays, that they don't need the extra power supply for the relay board, but this is wrong. The output of the BCS is only meant to be used as a trigger and not to power relay coils or other devices.

Jon and OneHoppy,

Thanks!! Man, do I feel like a dumba$$ now! LOL I clearly see how it works now. Had I viewed it as something like an SSR originally, I would have grasped it much sooner.

Thanks again!!

Geoff

Kurt, are you using the WYSE thin client in place of a pc? If so, how well does it work? Which model are you using? Will it work with a touch screen monitor?
