Product overview
EL9xxx 59Version: 3.9
The EL9540 system terminal contains an overvoltage filter for the 24 V field supply, the EL9550 for the 24 V
field and system supply. The filter protects the EtherCAT Terminals 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.
In the EL9550-0012 variant, the current load is 10 A for both the field supply and the system supply. The
higher system supply is advantageous for the supply of Embedded PCs that have a higher current
consumption.
The EtherCAT Terminals EL9540 or EL9550 protect the terminal station from damage in particularly harsh
environments. The ship classification organisations require the use in shipbuilding applications and in the
onshore/offshore sector.
