Characteristics

 

The compact process controller device key 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 diagnostics function 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 binary feedback are optionally available.

■ Compact and robust stainless steel design
■ Easy start-up via Tune function for position and process controller
■ Contact-free position sensor
■ Integrated pilot air duct with spring chamber aeration
■ PROFIBUS DP-V1, EtherNet/IP, PROFINET, Modbus TCP or büS (Bürkert System Bus)
