Type 8694-Digital ElectroPneumatic Positioner for The Integrated Mounting on Process Control Valve

Brand: Burkert Fluid Control Systems
Does not ship to United States

Compact positioner for integrated mounting on pneumatically operated process valves. Remote setpoint adjustment via a 4-20 mA signal or through AS-Interface. A contact-free Analog position sensor measures the position of the valve spindle.

Simple installation through automatic tune function and setting through DIP-switch: Close tight function, Characteristic curves selection, Reversal of effective direction, Switching manual /automatic operation, Binary input.

Additional parametrization options are possible through DTM devices. A software interface can be used for, amongst others, linearization of the operation characteristics by using free programmable fixed points.

The valve position indication is shown through LED components. As an option an Analog position feedback can be integrated.
