I am carrying out a project to activate an electro-pneumatic valve to activate it with a pulse generator, from the activation of a brand, I wanted to know if it is possible and in which way I should proceed, with a power take-off or with PWM. Thanks in advance

If it expects PTO, then it's pulse train output (not the mechanical power take-off term you called it). If it expects pulse width modulation, then use that. Most likely it is PTO. However, that does not make it true, just of all the brands of valve controllers I know about, more are PTO than PWM. SebastianPia Good afternoon, I hope everyone is doing well.
