Re: [beagleboard] 4-20 ma measurement with beaglebone black

Hi, I'm designing ESD protections to 4-20 loop interface on Beagle Bone analogic input. which is the clamp voltage of any TVS zener that i could use? Thxs El martes, 10 de abril de 2018 a las 16:04:08 UTC+2, robson...@gmail.com escribió: > Hi > > As I am also working on beaglebone

Re: [beagleboard] 4-20 ma measurement with beaglebone black

Hi As I am also working on beaglebone to measure 4-20mA sensor output with Receiver module using less power can anyone help me out with code to interface

There is a TI reference design for 4-20mA loop interfaces http://www.ti.com/tool/tida-00550. It is designed as a cape. Iain On Thursday, August 18, 2016 at 4:24:45 PM UTC+1, Graham wrote: > > If you would think to Google "4-20 mA receiver" you could learn a lot. > > Peripheral IC's from TI and

If you would think to Google "4-20 mA receiver" you could learn a lot. Peripheral IC's from TI and Maxim that have most everything you need all ready designed in. Modules you could interface to the BBB, etc. Application notes on how to design receivers, and things to worry about, common
