Scaling resistance to voltage

Deanne 12 months ago updated by Gustav Widén (System support) 11 months ago 7

I am trying to calibrate a level sensor that has a resistance output of 240 ohms (empty) to 33 ohms (full). The calibration below was what the setup is currently, but I am getting a high error on the VIN input. I am looking to fix the min and max, but I am unsure of how to scale this to voltage. I am getting a raw value of ~4999 at full.

Using a resistance output sensor on MC43

Deanne 12 months ago in Master modules / MC4x updated by Anders Olsson 12 months ago 1

A customer has purchased a resistance output level sensor (240-33 ohms). I have tried to find more information regarding converting this to a VIN, but couldn't find too much. I am wondering what else needs to be done other than incorporating a voltage divider in their circuit.

Would it be possible to change VREF to 8V ?

Ambient air temperature sender

Matthew Herzig 12 months ago updated by Gustav Widén (System support) 11 months ago 3

I thought this would be easy to find but having no luck.  I have a request to read the outside ambient temperature on the MD4-7 and not having any luck finding anything to do this with.  If all else fails the standard ones I have used for hydraulic fluid might work in a pinch but unsure how accurate that would be.  If this is something anyone has any ideas on I would appreciate any feedback.

XC43 Current Outputs Bounds for short and open load

Thomas Murgolo 12 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 12 months ago 1

Hello, I am working with an XC43 current output that controls a bidirectional valve and want to make sure I use the right resistor to avoid problems with getting short and open load errors. I have found the minimum resistance for my case is 20ohms based on Appendix A in Parker's Family instruction book, but I am not sure how to find the maximum. Any help would be appreciated.

i am starting to use the g12's for the first time. they freeze in the middle of uploads.

do you have ability for updates and how do you do it.

we probably bought about 20 of these

MC42 supply

hongxiang yu 1 year ago in Master modules / MC4x updated 1 year ago 3

Hi 

  I have a project MC42 for embedded Simulink models which is only possible in MC4x. But I got a information that Parker do not produce MC42 module anymore.  Is that true ?  If yes, Have any solution for simulink models in IQAN ?

DOUT voltage when not enabled

Kai Rasporich 1 year ago in Master modules / MC4x updated 10 months ago 2

Hello,

I am having some trouble with the Parker MC41. I have a display button on another MD4 that enables / disabled the output on Pin 45 (DOUT-HS). I am seeing a proper system voltage of 12.26V when the value is true, however when I set it to false Pin 45 goes to 11.68V. Is this normal behavior? Should I have some sort of diode in there to get the desired on/off I am expecting?

Thank you.
