Leonv33 Posted September 13, 2019 Report Share Posted September 13, 2019 What would be the maximum current rating for the 5v sensor supply on the expansion connector. Cannot find it anywhere, currently has 4 sensors on it consuming max 13mA and want to add another max 10mA Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Leonv33 Posted September 13, 2019 Author Report Share Posted September 13, 2019 Most other ECU makers advertise a max mA output. I did find the Thunder has 5volt max 200mA supply. How about this one ...anyone? Quote Link to comment Share on other sites More sharing options...
Richard Hill Posted September 13, 2019 Report Share Posted September 13, 2019 im sure you will be fine with the extra current. one way to check is in pclink go to runtime values f12 and look at the ecu tab it will tell you if the 5 volt supply is ok or not.

Leonv33 Posted September 13, 2019 Author Report Share Posted September 13, 2019 On the subject of the expansion connector regarding the signal ground. All my temp and pressure sensor grounds come through here but how about frequency based sensor ground ? can that also come through here (interference distortion) Just making a turbo speed input using Richard's example from another post, thanks again Richard :-) Help always appreciated!!

Adamw Posted September 14, 2019 Report Share Posted September 14, 2019 The external 5V supply is very generous in the Link ECU's. It is officially rated to 1500mA. There is also a seperate reg for most of the internal stuff such as pull-ups etc so you dont need to factor those into your calcs. Quote Link to comment Share on other sites More sharing options...
