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