Pwm 0-10v Cables

Is it possible to solder my own pwm cables for ec fans? I need a lot, and considering the sale price it just gets too expensive. Plus none of the plugs even fits my fans. I need to get these through small holes in my walls and therefore would have to desolder and resolder the plugs. I just need a standard pwm signal (0-10v). Could I build my own cables for this application? What format does the main unit give on the output? Is it 0-10v or pwm?
thanks!
ps: i think the Sensors are priced fairly. The pwm outputs are not. Simply adding two pwm outputs cost as much as your entire fan ec unit in another shop - well, actually the gse ec Fan unit is cheaper… :( I do not see the logic in that honestly.
Thanks Alain,
I understand that. But can you still let me know what signal is actuality given out on the port? A 0-10v converter board with read write processor and psu costs 4€ on ebay. It is obviously bulkier than your slim solution and involves some diy, but I would not mind in that case. I just can not spend an additional 700€ for breakout cables….. it’s too much. The whole unit explodes in price with pwm. Or maybe you could think about offering a Bus distributor with pwm built in?
Hi
Next to the RJ45 (Primaklima) and Stereo-Jack 3.5 (Can-Fan) you have a terminal block you can screw your cable to the terminals.
The pricing is depending on the material costs. The 0-10 PWM controller has much more components. The safety for external cables, have read and write processors and a own power supply on board. All this normal sensors don't have.

Hi
I'm asking to read carefully the description of the product. https://smartgrowcontroller.com/shop/product/sg18-sgc-0-10v-or-pwm-output-4542
Signal output provides 0-10V or PWM signal (Pulse-width modulation) You can set this with a Jumper.
If you need many the price explode, I agree. Until now I was counting with 2pcs for intake and exhaust fan + eventually one more for the Light controller. Under this condition it will be cheaper as a single controller.
Similar as we have made the https://smartgrowcontroller.com/shop/product/sg31-sgc-satellite-12-relay-exit-4954 I plan to make something with I/0 and 0-10V/PWM this will reduce the cost drastic if you need many in and output signal.
I agree the price seams high, I'm obligated to work with distributors and shops to make quantity's, I can not sell directly on e-bay or I will loose our dealers/partners. If they can not make money on it they remove it from the product range.
