14.1.5 Suppressor circuit for inductive loads
High induced voltages may be produced when inductive loads are switched
off. Because of this, the transistor outputs have internal suppressor circuits
to +24 V.
As shown in the diagram below, the voltage when switching off inductive
loads is limited to -29 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.
