Type Description
The compact Process Controller Type 8693 is optimized for integrated mounting on the pneumatic actuators in the process valve series Type 23XX/2103 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 through the variance comparison. Due to the analogue feedback all analogue values on the controlling level can be transferred. With integrated diagnostic functions operation conditions of the control valve can be monitored. Through status signals, valve diagnostic messages are transmitted according to NAMUR NE107 and recorded as history entries. The parameterization of process controller and positioner can be carried out automatically.The easy handling and the selection of additional software functions are done either on a big graphic display with backlight and keypad or over a PC interface. The Positioner registers the valve position without deterioration through a contact-free, analog position sensor. The control of single or double-acting actuators is done without internal air consumption. Communication interfaces such as Profibus DPV1 or DeviceNet and analogue as well as binary feedback can also be chosen.
1）Compact, robust stainless Steel design
2）Easy start-up by Tune fuction for position and process controller
3）Contact-free position sensor
4）Integrated control air routing with spring chamber aeration
5）Profibus DPV1 or DeviceNet communication (option)
