I think I misunderstood what controller you were referring to. Got a link to what you have?
In purchased form, it will not take input from an outside sensor. It generates the PWM signal on manually commanding a duty cycle with the rotary knob.
Pricey, but not clear on how it works. Looks like it just takes a PWN signal to turn the relay on/off. I imagine there is no control in terns of fan speed other than on/off.I saw that MSD makes a relay block, the description says that it can handle PWM?
Clean up your wiring with an MSD Solid-State High Current Relay Block. This high current module takes the place of 4 standard relays and eliminates unsightly wiring. Four independent channels can be activated using either power or ground. Each channel is capable of handling up to 35 Amps of...www.speedwaymotors.com
Please forgive my innocence on this subject. I'm just looking into this. Thanks
Voltage test. As you vary the duty cycle the voltage will change from source to 0.Since there isn't a simple test controller for PWM- (it seems), is there any other way to test the 2 units I have for functionality? I'd just like to confirm they both work.
