Using a 24v Off The 832 Energy Bar

[scriptmonkey]

So I am looking to install a CO2 scrubber and integrate with Apex using a 24v solenoid. Everything is 3/8" so that rules out the 1/4" Neptune one.

So inspired by BRS I am looking at a 24v one:

So instead of using a 24v power supply, anyone see an issue with powering it using one of these off of the EnergyBar 832:

I see it calls out solenoids in the description just want to make sure I am not missing anything.
Thanks for the Peer Review

You are going to need a 3-way 2-position solenoid. Something like a MettleAir 3V310-10-DC24-1. This is what I have ordered. For the normally closed (ie when power is lost the valve closes). Port A to your skimmer pump. Port (P) is normally open and port (R) is normally closed.

Just use the Apex SV1.

Just use the Apex SV1.

And use adapters to get it to 1/4”

I am worried about air restriction becoming even more of a factor in skimming ability.

This didn't work for me. After I put the Y in and with the solenoid being only 1/4 in. and the reactor 1/2 in. opening and closing the solenoid didn't seem to change the direction of air much. It still seems to pull all air from the reactor. Seems the reactor is causing less resistance than the 1/2 to 1/4 conversion.

Going with a 3V solenoid you will need to step down the 24V accessory port or use a 3V power supply. I got a step down for my fiberoptic light that goes into my lid. Check out my build thread for the full details. I used the accessory bare wire as mentioned then a 24v to 5V convertor that had USB ports that plugged right into my lid light. Put the accessory port on a timer and now my lid light comes on automatically.

I am planning a similar setup for my CO2 scrubber and plan to use the 3/8 McMaster solenoid and another accessory bare wire. Saves on the 110V plugs and all the power bricks.

Just watch the total Amps being drawn from the 24v supply. If memory serves the EB832 has a 4Amp supply and some of that is used for the CPU and relays etc.
If that supply gets overloaded the whole system will lose power.

I believe it is 100w max on 1link+ 24v ports, no more than 30w per 24v port.

I might be missing something but it doesn't seem that the EB832 monitors Amps & Watts for Accessory 24v ports. You can monitor the Amps & Watts at an EB832 level for all ports. You can enabled monitoring on the Accessory port but that will just log the on and off events for the port.

He is warning you to not overload the 24v supply, or you will have a dead EB832. Unrelated to the 120v monitoring.

(You need to do the math yourself; no more than 30w per 24v port and 100w total on 1link+ 24v ports)

Yeah i got that. But how do you monitor the usage when there are no logs for power usage on 1Link or accessory ports?

Use these valves the work amazing and hook to the 24v port on e838 bar. I use 4 of these controlled by my apex to control co2 scrubber. 4 because my skimmer has 2 pumps

 

[((FORDTECH))]

These valves are full open port there is no restriction at all get the half inch version and then use John guest fittings or whatever size you need

 

[((FORDTECH))]

Here’s my set up

 

[TheHarold]

You look at your device. It will always tell you the power draw.

Volts* Amps = watts. Given you now know the maximum watts on 1link and 24v ports, that should be all the information you need.

What size tubing are you using? 1/4 inch is pretty small the same size as the neptune solenoid.

So sorry sent wrong picture should have sent the 1/2 one let me look for it and repost

Sorry for mix up looks like the exact valves I bought maybe out of stock but these look to be exact same except these have a manual control on valve aswell as electronic control. Mine only has electronic control

The 24 v port on energy bar supplies 24v and these valves work from 9-24v. With that being said you can run 2 of these valves from 1 port. 24 v split in half 12v each valve is within the working voltages
