I need to figure out how to read & write (sense/control) a 2 amp 20vDC PWM line.
Every 10 minutes I would need read the pulses on a line, and based on what I read, mimic that on a 2nd line. (so if one is pulsing at 100/sec, I need to set the 2nd line at 100/sec, and follow the 1st every 10 minutes).
Both lines are drawing about 2 amps. frequency can go rather high, as well as approach 100% duty cycle.
I was thinking some sort of optocoupler with a mosfet or power transistor with a heat sink?
Can anyone recommend something?
