Notes
| Safety Information | Input and output must be safely isolated from any hazardous live parts! |
|---|---|
| Note | Use shielded signal cables!Only use shielded signal cables for analog input and output signals.This ensures the device maintains its specified accuracy and immunity to interference, even when external disturbances affect the signal cable., Additional setting options via the WAGO Interface Configuration Software |
