Hello dave10010,

Thank you for reply.

 

My predecessor designer have used it as PWM input driven open collector only.
But I think it needs Pull up resister and dc voltage.

 

Thank you.

ECM PWM input specification for throttle control

Hello,

 

I want to know CAT ECM PWM input specification for throttle control .

 

For example, 5VDC,Pull up resister 1k,open collector.

 

Thank you.
