A relay apparatus comprises input ports, output ports, and first and second relays. The first relay comprises: a first contact group comprising n≥2 first contacts arranged in parallel and moveable between open and closed positions by a first common armature; and a second contact group comprising n second contacts arranged in parallel and movable between open and closed positions by a second common armature, wherein the first and second contacts are arranged in series in pairs. The second relay includes m<n contacts arranged in parallel and moveable between open and closed positions by a third common armature. The first and second relays are arranged in series between the input and output ports such that the relay apparatus has plural parallel switching paths. A contact of the second relay is arranged in series with a first contact of the first contact group in m switching paths.

Relay apparatus and safety switching device with relay apparatus

A method for configuring a modular safety switching apparatus having electronic modules comprises: a) selecting a configuration data set of the apparatus from a database and transmitting the configuration data set to a computing apparatus, wherein the configuration data set is processed by a computer program to generate a target configuration of the apparatus and the electronic modules; b) displaying the target configuration; c) plugging one of the electronic modules into one of the module slots of the module row; d) setting a rotary switch position of one or more rotary switches of the electronic module; e) determining an actual configuration of the electronic module configured according to c) and d); f) comparing the actual configuration with the target configuration; g) displaying whether a deviation exists between the actual configuration and the target configuration; and h) repeating c) to g) for each additional electronic module.

Procedure for configuring a modular safety switching device

A method for configuring a modular safety switching apparatus having a plurality of electronic modules arranged in at least one module row, comprises: selecting, via a graphic user interface of a software-based configuration tool, a number of safety functions of the safety switching apparatus and logic requirements to be met by the safety switching apparatus; generating a configuration of the safety switching apparatus via the configuration tool by automated selection of the electronic modules from a plurality of types of electronic modules in order to implement the selected safety functions of the safety switching apparatus and logic requirements to be met by the safety switching apparatus; and storing the configuration of the safety switching apparatus as a configuration data set in a configuration database.
