EL9540, EL9540-0010, EL9550, EL9550-0010, EL9550-0012 - Introduction and Technical Data
Surge filter terminals
The surge filter terminals protect the EtherCAT Terminals from conducted Surge voltages, as they can be caused on the supply lines by high-energy, dynamic disturbance variables, e. g. switching overvoltages with inductive loads or overvoltage with indirect lightning strikes.
The EL9540, EL9550 and EL9550-0012 EtherCAT Terminals enable the terminal station to be protected against damage in particularly harsh environments, such as in the on- and offshore area.
The EL9540-0010 is particularly suitable for the protection of analog terminals, the EL9550-0010 for digital terminals, and can be used, for example, in shipbuilding.
The EL954x have a filter for the 24 V DC field supply and the EL955x have a filter for the 24 V DC field and system supply.
For the EL9550-0012 variant, the current load for both the field supply and the system supply is 10 A each. For the EL9550-0010, the total field and system supply is 10 A. The higher system supply is advantageous for the supply of Embedded PCs, which have a higher current consumption.
