Dear friends
I am working on a project drag car. using FuelTech FT600 and hardwire pdm15. I am currently I am working power output layout. In FuelTech documentation they mentioned to use hella relay to activate the transbrake and brake line lock. Can I get some a
Guidance about wiring them by using the pdm instead of using the relay as I understand the relay activation will be from negative side with pwm to control the transbrake and brake line lock operation.
You can do this as long as the PWM frequency is not too high. The PDM only reads the input voltages at 100Hz or so, so if the PWM frequency is too high then you will miss the detail in the signal and get a sporadic output signal as a result.
