I bought the Hydros cable that breaks out the 0 to 10 volt outputs into 4 separate cables. It seems to work like a champ. I would like to control my Jebao SW8 pump with it. Unfortunately the 3.5 mm male plug doesn't fit the 0 to 10 volt input on the Jebao controller. The controller port has a tiny male connector. Anyone know where I can get a female connector that will fit the Jebao controller port?
 
Interesting...

Here’s what you need to know:

The Jebao "External Controller" Port:

Jebao’s 0–10V input port is a small 3-pin male connector—very similar to a JST-XH 3-pin or DuPont-style header.

It’s not a 3.5mm audio jack, so the Hydros breakout’s standard male jacks won’t fit directly.

What You Need

To connect Hydros to the Jebao SW8 controller, you’ll need:

1. A compatible female plug for the Jebao 0–10V port. Users have reported that the JST-XH 2.54mm 3-pin female connector fits most Jebao controllers.


2. Wiring guide so that the signal, ground, and voltage reference are connected properly.

Thanks. I found the same info using Google but it is wrong. I've ordered a 5.5mm x 2.1mm plug from Amazon. I should know tomorrow if it works.

Finally got the right parts and now my Hydros X4 is controlling my Jebao SW8.

All the info I found online was wrong.

Through trial and error I found a plug from Digikey that fits the Jebao 0-10 volt input. I then soldered it to to a 3.5 mm connector from Amazon.

A bit of experimenting showed that Hydros output from 3 to 10 volts will run the pump at variable speeds.
