Abstract
An electropneumatic position regulator for controlling a pressure-medium-operated actuating drive to which compressed air can be applied via a working connection of the actuating drive. Compressed air is made available to the position regulator via a feed pressure connection, and the pressure regulator includes an electronic control unit configured to assume a safety position in the event of a fault. When the electronic control unit assumes a safety position, a downstream signal output unit, which acts as a driver stage, generates at least one binary fault signal which is indicated in an externally perceptible manner (e.g., visually and/or audibly) by at least one signaling device fitted externally to a housing of the position regulator.
