1. An interface arrangement for connecting at least one control device to a plurality of field instruments, comprising:
a carrier board having a plurality of signal channels, each one of the signal channels having a first connecting device and a second connecting device, the first connecting device configured for connecting to a respective field instrument and the second connecting device configured for connecting to the at least one control device,
a connector configured for electrically and mechanically connecting to a complementary connector of a signal processing device, arranged between the first and the second connecting device of each one of the signal channels, and
each signal channel having an electrical interface configured for releasable connection of respective surge protection modules and being arranged on the carrier board between the connector and the first connecting device, each interface being connected to an electrical resistor, and
a surge arrester electrically connected to the electrical interface of each one of the signal channels, and arranged at least partially on the carrier board, or arranged at least partially in the carrier board, or arranged at least partially on and in the carrier board, the surge arrester configured for arresting surge voltages and/or surge currents that may occur.
