EL9540 | System terminal, surge filter and field supply

The EL9540 system terminal contains an overvoltage filter for the 24 V 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 protects the terminal station from damage in particularly harsh environments.
