型号描述
紧凑型过程调节器 8693 适合集成安装在 23xx/2103 系列过程调节阀的气动驱动装置上，专门针对卫生工艺条件的相关要求设计而成。将过程参数的实际值直接作为 4-20 mA 信号传输到 PT100 上，或者作为频率信号传输到设备上。过程调节器会根据额定值与实际值的比较结果，计算安装在下级位置调节器的额定值。借助于模拟的反馈信号，可以将模拟值传输到控制层面上。过程和位置调节器的参数化可自动进行。通过带有背景照明装置和薄膜键盘的大型图像显示器或电脑接口，进行简单操作和大量软件附加功能的选择。位置调节器会通过一个无接触式的模拟位置传感器检测阀门位置，期间不会产生磨损。在不消耗自身空气的情况下，进行单作用或双作用驱动装置的控制。可选择使用通讯端口 Profibus DPV1 或 DeviceNet 以及模拟或二进制反馈信号。
1）紧凑型不锈钢设计
2）带有背景照明装置的图形显示器
3）利用过程和位置调节器实现极简便的调试
4）大量的软件附加功能
5）驱动装置里的集成式控制空气引导系统
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)
