speed controler and program modes of dc pumps
#2
Hi Michael, today that can't be done but I think I'm adding that very soon, I have an update ready in a day or two and will probably start this for next update as I've been planning it for a long time now. Here's some old screens I made as an example. I don't like these now and have a better idea but I think this is what you're referring to.

There is a system that allows you to turn on/off AC outlets when a feed starts with timer good for up to 99 minutes. You could plug the DCT9000 AC-DC adapter into the power bar and use this feature to shut it down during a feed and it would resume when feed ends.

That link for the DC motors is what I was trying to explain on your other question for the DCT9000, however I think I got confused because the Jebao DCT are PWM controllable so much easier to work with.

To clarify there are 4 ports that currently turn on/off anything that uses DC power, later these ports will also be able to adjust the speed of the motors.

There's another 4 accessory ports that can put out 0-5v or 0-10v PWM signal or 0-10v Analog signal using jumpers on PCB, currently nothing can be done with these but that's what I'm going to work on soon.

These are the port's you would use for DCT8000 and the Jebao WP and PP series power heads or anything else that can be controlled using these signals.

That adapter for the Apex isn't required as it only converts the signal to 0-10v for the Apex.

These pumps operate on 24v DC and come with an AC-DC adapter. You would use that to power the pump and then connect the GND and signal wire to the controller.

If you can find some 3pin cables to fit the Jebao it's easy otherwise to have to cut the cable on the pump or take apart Jebao controller and use cable from it. A while ago I ordered some from ebay but there was a notch that caused issues.

Using the Jebao controller you can get the pinouts easy. You'll see 24v across two pins and 0-5v on the 3rd pin which is signal. You would then run 24v from AC adapter directly to pump and connect GND and signal wire directly to controller.

For my powerheads I ended up taking the patch cable out of the controller to use. Here's an image of what it looks like, this is all you need. The USB connector would be a 4pin to match the controller (original controller used USB), the small round connector is a DC socket for 24v AC-DC adapter and the large connector plugs into the pump.

With all that said these can still be used today (and the future) with the LED channel outputs. Those put out 0-5v PWM so you would connect the signal pin to an LED channel. Then you can set that channel in the light schedule with different speeds and the pump would ramp up and down in sync with the lights.
