KL9540-0010 | System terminal, surge filter field supply for analog terminals

The KL9540-0010 system terminal includes an overvoltage filter for the 24 V field supply. The filter protects the Bus Terminal from line-bound surge voltages that can occur due to high-energy disturbances such as switching overvoltages at inductive consumers or lightning strikes at the supply lines. The KL9540-0010 can protect Bus Terminal stations in particularly harsh environments from damage. The use is stipulated by the ship classification organizations in shipbuilding and on/offshore applications. The KL9540-0010 is intended in particular for the protection of analog terminals; the standard variant KL9540 for digital terminals. The LED indicates the 24 V rated voltage. The terminal does not transfer process data to the higher-level control system.
