The compact process controller device Type 8693 is optimised for integrated
mounting on the pneumatic actuators in the Type 23xx/2103 process valve series
and is specially designed for the requirements of a hygienic process environment.
The actual value of the process factor is directly supplied to the device as 4 - 20 mA,
PT100 or a frequency signal. The process controller calculates the setpoint for the
subordinated positioner based on the variance comparison. Via the analogue feedback,
all analogue values on the control levels can be transferred.
The integrated diagnostic functions are used to monitor control valve operating
conditions. Valve diagnostic messages via status signals are issued in accordance
with NE107 (NAMUR) and recorded as historical entries. The parameterisation
of process controller and positioner can be carried out automatically. The easy
operation and the selection of additional software functions are carried out either
via the large graphic display with backlight and keypad or via COMMUNICATOR.
The positioner registers the valve position without deterioration via a contact-free,
analogue position sensor. The actuation of single or double-acting actuators
is carried out without internal air consumption. Communication interfaces such
as PROFIBUS DP-V1, EtherNet/IP, PROFINET, Modbus TCP, büS (based on
CANopen) and analogue as well as digital feedback are optionally available.
