FnIO module - 4-channel current input module ST3134
processes current signals from 0 to 20 mA
Delisting
If you have any questions, please contact our technical application consultants.
- The analog input module processes current signals from 0 mA to 20 mA
- Galvanic isolation of the input signal from the system level with a resolution of 14 bits
- Power supply via internal system voltage
- Common ground potential of the input channels

The analogue input terminal processes signals of the standardized value 0 mA to 20 mA. The input signal is transmitted electrically isolated to the system level with a resolution of 12 bits. The internal system voltage is used for the power supply. The input channels of the module have a common earth potential.
