Cognex camera InSight 1400 output conversion into 4-20mA
« on: May 03, 2017, 05:50:21 AM »
Hi guys,


Newbie here - have patience. 


 :merci:


As a topic title says.. If someone would be so kind to point me in a direction..

ATM I am mostly concerned about camera value output continuosity..

Which means - those vision cameras ( in this case some Cognex 1400 b&w model) outputs values only when triggered.

This particular application is to measure some height which is afterword processed at industrial PC as in/OUT of tolerance.

Since is rather complex to change PC SW also - what I would like to do is to swap laser distance sensor (4-20mA output) with a Computer Vision Camera.


I think that camera can be placed in continous mode so the measurement will be constantly "feeded" to the output - but question is - how to easiest convert it into a 4-20mA for PLC


I know that question I ask is very "in general" but if someone could point me towards somewhere - it would be of great help also..



Kind regards.
