8694 Digital Electropneumatic Positioner (for integrated mounting on process control valves)

Contact-free position sensor, easy start-up (automatic Tune function), compact robust stainless steel design, integrated control air routing,?Fieldbus interface AS-Interface.?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 parametrisation options are possible through DTM devices. A software interface can be used for, amongst others, linearisation of the operation characteristics by using free programmable fixed points. The valve position indication is shown through LED components. As an option an analogue position feedback can be integrated.
