Digital electropneumatic positioner for the integrated mounting on process control valves

BURKERT – TYPE 8696 Compact positioner for integrated mounting on pneumatically operated process valves. Remote setpoint adjustment via a 4-20 mA signal. A contact-free continuous 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. 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.
