Offset of analogue reading from sensor

Help & Support Robot Parts
1

i want to use a sensor with ±2 V output but my PLC can only accept values in the range 0 to 10V.
Did somebody know how to get a 2 V offset so that when the sensor give -2V i get 0V and when the sensor is at +2 V it give 4 V
or something like that !

je désire utiliser un DFRobot 50A Current Sensor, celui a une sortie analogique de ±2V. L’automate que j’utilise a des entrées analogiques de 0 à10V (donc pas de valeurs négatives ! ). Avez vous un circuit permettant de changer l’offset de la lecture analogique pour que les ±2V entre dans 0-10V V ???

Hi @agul!

You could use an op-amp circuit. I suggest you check these links:
