Abstract

A system has at least one output device, the output device having a first set of output terminals connected to a corresponding field device. Each output device has a corresponding redundant output device having a corresponding first set of output terminals connected to the same corresponding field device as the corresponding output device. The output device and the redundant output device each have a second set of output terminals corresponding to the first set of output terminals, the second set of output terminals being connected to an apparatus for controlling the information outputted from the first set of output terminals.
The apparatus comprises a plurality of switching elements, having a set of first and second contact points.
Each of the second set of output terminals of the output device being connected to a corresponding first contact point, and the second set of output terminals of the redundant output device being connected to the corresponding second contact point. An activating element activates the plurality of switching elements in response to a control signal from the output device and the redundant output device such that the information outputted from the output device or the redundant output device is prevented from being coupled to the field device.
