Abstract

A device, preferably a plug-in module, for communication between a controller and a field device. The device includes contacts, wherein a first subset of the contacts is electrically conductively connected or connectable to the controller and a second subset of the contacts is electrically conductively connected or connectable to the field device. The apparatus further includes a circuit having an input electrically conductively connected to the first subset of the contacts and an output electrically conductively connected to the second subset of the contacts. The circuit includes a voltage-limiting unit adapted to limit a voltage at the output, and a current-limiting unit adapted to limit a current between the input and the output and to interrupt the current when the voltage-limiting unit responds.
