Title: BRX PWM
Post by: durallymax on March 22, 2021, 09:17:23 AM

I have a project that needs proportional control of valves. I am debating between using the built in PWM on a BRX(if they make it back in stock in time)or simply interfacing with a valve PWM driver that just needs an analog signal send to it.

Any suggestions to use built in vs a driver? From what I see driver will be less programming but more money. If I did use the BRX to do PWM, what type of interposing devices are typically used between the BRX output and valve coil (5W in this case)? SSR?

Thanks

You might want to also post the application/implementation question on ADC's community website to get other/more eyes looking at it.

As a follow-up, I ended up sending a 4-20mA signal from the BRX to a PWM driver from Kar-Tech for this application.
