Connection of active-type analog sensors (current) with electrically \ isolated power supply to the analog inputs¶
The following figure shows the connection of active-type analog sensors (current) with electrically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.
The following measuring ranges can be configured DA502 - Digital/Analog Input/Output Module DA502 - Digital/Analog Input/Output Module:
Current | 0…20 mA | 1 channel used |
Current | 4…20 mA | 1 channel used |
For a description of the function of the LEDs, please refer to Diagnosis and displays / Displays DA502 - Digital/Analog Input/Output Module.
Unused input channels can be left open-circuited, because they are of low resistance.
