Connection of active-type analog sensors (voltage) with electrically \ isolated power supply¶
The following figure shows the connection of active-type analog sensors (voltage) with electrically isolated power supply.
Connection of active-type analog sensors (voltage) with electrically isolated power supply. 1 analog sensor requires 1 channel.
The following measuring ranges can be configured AI531 Analog Input Module AI531 Analog Input Module:
| Voltage | -50 … +50 mV | 1 channel used |
| Voltage | -500 … +500 mV | 1 channel used |
| Voltage | -1 … +1 V | 1 channel used |
| Voltage | -5 … +5 V | 1 channel used |
| Voltage | -10 … +10 V | 1 channel used |
| Voltage | 0 … +5 V | 1 channel used |
| Voltage | 0 … +10 V | 1 channel used |
The function of the LEDs is described under Diagnosis and displays / displays AI531 Analog Input Module.
In order to avoid error messages or long processing times, it is useful to configure unused analog input channels as “unused”.
