ELECTROPNEUMATIC POSITION CONTROLLER AND FIELD DEVICE WITH AN ELETROPNEUMATIC POSITION CONTROLLER

摘要

Electro-pneumatic positioner for a pneumatic actuator for actuating a control valve, such as a control valve, a process plant comprising at least two modular pneumatic slots for occupancy, each with a modular pneumatic component, such as an electropneumatic converter or the like, wherein the at least two pneumatic slots and the pneumatic components so modular are tuned that their pneumatic interfaces merge into each other when occupying a pneumatic slot, and at least one pneumatic control output for outputting a pneumatic control signal to the actuator, wherein the at least two modular pneumatic slots and the at least one pneumatic control output form a pneumatic series connection.
