Controlling LED Piranha with PWM controllers

In my project I need to control intensity of 8 LED Piranha by using following components(see an attached file):
- LED RGB Controller ( simply changes combination of R,G,B colors)
- OPTO22 ODC15 Solid state relays module
- 8 independent PWM controllers (work from software and change output voltage from 0 to 12VDC)
- 8 LED RGB Piranha 12VDC, 25mA, with resistors
My point is to make dimmable 8 LED Piranha while the LED Controller changes colors. Each LED performs according to the PWM Controller output voltage.
I've already made and tested only one LED. Works perfect.
Don't know where to connect other 7 negative outputs from PWM's.
Do I have to have 7 more OPTO22 or there is another solution?
Need help.
Thank you.
