Connection Examples

Use shielded signal lines!
Only use shielded signal lines for analog signals and I/O modules which are
equipped with shield clamps. Only then can you ensure that the accuracy and
interference immunity specified for the respective I/O module can be achieved
even in the presence of interference acting on the signal cable.
Disable unneeded inputs!
The I/O module (2AI Resistor Bridge (Strain Gauge)) has very sensitive
measurement inputs.
Disable unused inputs to avoid unwanted error messages.
Section "Configuration and Parameterization with WAGO-IO-CHECK" describes
how one input, or the diagnostics of individual inputs, of the I/O module can be
switched on/off.
