8.2.7Arc-Quenching for Inductive Loads

Note

Digital output modules have integrated circuits on the module to quench inductive loads (refer to the technical specifications of the output modules).

Exception: The 458 digital output module allows the switching of inductive loads with contact protection submodules.

The integrated circuits on the modules for quenching inductive loads are disabled if the load circuits are interrupted, either

Soperationally by contacts and switches,

Sor by fuses in the event of a fault.

This can result in excessive, inductive breaking voltages which put fault-free operation at risk.

You can prevent this with additional, external quenching circuitry for the inductive loads.
