As shown in the diagram below, the voltage when switching off inductive
loads is limited to -12 V. In order to prevent system malfunctions caused by
voltage peaks (e.g., coupling on analog cables), it is recommended to use a
suppressor circuit (RC suppressors or flyback diodes) directly on inductive
loads.
