Magnetic capacitance with inductive loads
Note
Note that an inductive load connected to the DO channels can induce voltages in the case of
electromagnetic interference of a strong magnetic field. This can cause a short-circuit error
message.
Remedy:
• Spatially disconnect the inductive loads or shield against the magnetic field.
• Set the parameters for the readback time to 50 ms or higher.
