The surge filter terminals protect the EtherCAT Terminals from line-bound surge voltages that can occur on the supply lines due to high-energy, dynamic disturbances, e.g., switching surges from inductive loads or overvoltage from indirect lightning strikes.

The EL9540 EtherCAT Terminal can be used to protect the terminal station from damage in particularly harsh environments, such as onshore and offshore areas.

The EL9540-0010 is especially suitable for protecting analog terminals.
The EL9550-0010 terminal is especially suitable for protecting digital terminals.
Both terminals can be used in shipbuilding, for example.

The EL954x has a filter for the 24 V DC field supply.

Other surge filter terminals

With the EL955x series, additional terminals with a filter are available for the 24 V DC field and system supply (see chapter "EL9550, EL9550-0010, EL9550-0012").
