The Modicon X80 Discrete Input/Output Modules User Manual, 35012474.18, page 259, states there is no protection against inductive over voltage and recommended a discharge diode on each output.  See highlighted below.

Since the reference to diodes would apply to DC applications, the reference will be removed from the User Manual.
