Need help translating from Chinese for pwm controller

(1/2) > >>

Jwillis:
I need some help translating .I can't find a manual or get information from the seller or find anything on the net about it.
Any help would be greatly appreciated.
I'm using this to control the speed of my coil winder that I'm converting from hand crank .That lets both hands free to control the wire feed onto the coils.
I know the black terminal block is from left to right is + power ,- Power and + Motor , - Motor . On the green terminal block the left terminal is connected to Vcc pin 8 on the TLP250 photo coupler shunted by a 1N4747 20v zener tied to ground. the right terminal is tied to the anode of the 817 optocoupler .I'm guessing the green terminal block  is for a remote start/stop
I couldn't find a decent picture or take one that was clear enough to view. so here's the link.

floobydust:
That URL takes me to a PWM controller with no green terminal block or opto-coupler.
Can you post a pic of the particular one you have.

Are we talking about this?   https://www.ebay.com/itm/153224958220
However, the bottom of the PCB does not seem to match the top.

   

   
Edit- Corrected PCB bottom thanks to @flooblydust

Jwillis:
Ah jeez sorry  :palm:
this is the right onehttps://www.ebay.ca/itm/1PCS-DC7-42V-10A-350W-DC-Gear-Motor-Speed-Control-16KHZ-PWM-DC-Motor-Controller/153224958220?hash=item23aceb510c:g:OWwAAOSwBFlbx-w8
I feel like a complete tool now :-DD
