EL9550-0012 | System terminal, surge filter system and field supply with up to 10 A

The EL9550-0012 system terminal contains an overvoltage filter for the 24 V field and system supply. The current load is 10 A both for field supply and system supply. The increased system supply is convenient for supplying Embedded PCs with higher current consumption. 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 EL9550-0012 protects 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.
