Type 8694 are compact positioners that combine simply and reliably with pneumatically operated Type 23xx/2103 process valves, and are specially designed for hygienic process environments.

Features

  • Compact, robust stainless steel design
  • Start-up by automatic Tune function
  • Contact-free position sensor
  • Integrated control air routing
  • Fieldbus interface AS-Interface (option)
  • close-tight function
  • inversion of the operating direction of the setpoint signal
  • characteristic curves selection
  • switching of manual/automatic operation 

Installation

Simple installation through automatic tune function and setting through DIP-switch

Operation

Functions are are activated using push-buttons and DIP switches or a PC interface. 

The position setpoint is set using the standard signal 4-20 mA. In addition, the enable can be controlled using the binary input and an optional position feedback can be integrated. Fieldbus communication via optional AS-Interface.

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.

Maintenance

They meet the demands of plant washdown environments thanks to their compact design, materials used, external seals, and integrated control air supply to the actuator.
