On/off control of pneumatic quarter-turn actuators and open/closed position signalling. Mounts directly on ACTAIR EVO / DYNACTAIR EVO actuators with a universal baseplate, providing a rugged, compact and integrated solution. Its integrated directional control valve eliminates the need for any pneumatic lines between AMTRONIC U and the actuator. The actuating time of the actuator can be set via AMTRONIC U's air flow reducer. AMTRONIC U can be connected to Profibus DP or AS-i field buses. AMTRONIC U has been specially developed to reduce control unit cabling. Connection via field bus enables both power supply and control information exchange with the process control system.

Benefits
A single aluminium base allows the positioner to be mounted directly on actuators of all sizes and generations, without installation components, ensuring direct control air supply without external piping.
With its modular design AMTRONIC U can be adjusted to customer requirements (limit switches, proximity sensors, field bus, heating resistor, actual-position feedback, etc.)
The fitted solenoid valve is protected from blows, corrosion and dust.
The aluminium actuating shaft increases the unit’s service life.
