Description 2 Description 2.1 Application The devices are used to convert a direct cur- rent input signal into a pneumatic output sig- nal for measuring and control tasks. They are particularly suitable as intermediate ele- ment between electric measuring devices and pneumatic controllers or between elec- tric control devices and pneumatic control valves.
