8611型eCONTROL 通用调节器 burkert

类型描述

8611 型通用调节器具有紧凑型的结构方式，非常适合同样采用紧凑型设计的调节系统。这种调节器经测试可兼容与所有 Bürkert 比例阀和传感器，在使用标准信号（4-20 mA、0-10 V 或 PWM 输出信号）的前提下，可以与各种非 Bürkert 调节阀相组合。这种具有 PI 特性的过程调节阀，配备了大量的附加功能。通过 3 个模拟输入端，可以将工艺实际值作为标准信号 (4-20mA / 0-10V)、电阻信号 (PT100) 或频率信号读入。通过电流或电压标准信号或者键盘，可以规定工艺额定值。特别适合温度调节任务，可以设计其下方安装有流量调节装置的级联式结构。通过控制比例阀和过程阀，可以在流体技术领域中完成各种各样的调节任务，也可将其应用于液态的或气态的介质。

Type 8611 - eConTROL - Universal controller

Type Description

Thanks to its compact design, the universal 8611 controller is especially designed for compact control system applications.It is compatible and tested with all Bürkert proportional valves and sensors and can be connected with every none-Bürkert Control valve by standard signal (4-20 mA, 0-10 V or PWM-output). The proportional & Integral (PI) process controller is equipped with many additional functions. The process value feedback can be supplied as one of three analog inputs; a standard signal (4-20 mA/0-10V), frequency or RTD signal; directly to the universal controller. The process switching points can be set via a 4-20 mA or 0-10 V signal or with the keypad For temperature specific control, it is possible to set a cascade structure with both temperature and flow as inputs. Thanks to the proportional control capabilities, a wide range of control functions can be performed in a variety of liquids and gas medias.

（1）Continuous, 2-point, 3-point and On/Off control

（2）Ratio control function

（3）Sensor inputs (4-20 mA, 0-10 V, frequency, RTD)

（4）Control of proportional, process and motor valves

（5）Bürkert proportional valves and flow meters are memorized
