Overview

The EL9540-0010 system terminal contains an overvoltage filter for the 24 V DC field supply. The filter protects the EtherCAT Terminal from line-bound surge voltages that can occur due to high-energy, dynamic disturbances such as switching overvoltages at inductive consumers or indirect lightning strikes at the supply lines. The EL9540-0010 can be used to protect the terminal station, especially analog terminals, aga...
