Technical Specifications
Detailed engineering parameters based on manufacturer documentation
| Parameter | Value | Parameter | Value |
|---|---|---|---|
Safety information | Input and digital output must be safely isolated from any hazardous live parts! | Note | Use shielded signal lines!Only use shielded signal lines for analog input and output signals.Only then can you ensure that the accuracy and interference immunity specified for the device can be achieved, even in the presence of interference acting on the signal cable.Additional setting options via WAGO Interface Configuration Software or WAGO Interface Configuration App |
