型号描述

坚固的紧凑型位置调节器，适合安装在标准化的推动和摆动驱动装置（参照 IEC 534-6 或 VDI/VDE 3845）上。带有分段式位移传感器的类型，也可用于调节 Bürkert 过程调节阀。通过电流标准信号 4…20mA 或 AS 端口（选项）规定数字式电气位置调节器即定位器 Side- Control BASIC 的额定值。另外，还有一个二进制输入端和一个可选的模拟反馈信号可用。分别通过一个机械式指示元件和三个彩色 LED 指示阀门开口度和装置状态。所有操作元件均处于外壳内部。调试过程自动进行，通过 DIP 开关可直接在装置上激活以下功能：- 密封关闭临界值 - 额定信号的作用方向逆转 - 特征曲线选择 - 手动/自动模式的切换。借助于通讯软件还能实现其他的配置和参数化可能性，例如通过一个可编程的修正特征曲线将运行特征曲线线性化。气动调节系统可同样地应用于单作用和双作用的驱动装置。其特征在于，在电气或气动辅助能量失效时，仍能保持一个定义的安全特性，在供应压力最高为 7 bar 时，可用的空气功率范围非常大。

1）紧凑型金属外壳
2）通过调谐功能实极为简便的调试
3）具有高空气功率的动态调节系统
4）可通过通讯软件参数化大量软件附加功能
5）根据 IEC 534-6 / VDI VDE 3845 进行安装

Type Description

The robust and compact positioner is designed to a standardisation acc. to IEC 534-6 or VDI/ VDE 3845 for assembly with linear and rotary actuators. In addition, the remote version with the displacement position sensor can be combined with Bürkert process control valves The setpoint setting for the electro-pneumatic digital Positioner SideControl BASIC occurs using a standard signal 4…20mA or with AS-Interface as an option. In addition there is a binary input and an optional analogue feedback available. The valve opening is signalled by a mechanical indicator element and the device staus is shown on three coloured LEDs. All the operational elements are found in the housing . The start-up happens automatically, and directly at the device the following functions can be activated through DIP switches: - Close tight function - Inversion of the operating direction of the setpoint signal - Characteristic curves selection - Switching between manual and automatic mode. Additional possibilities on configuration and parameter setting, for example, linearisation of the operation characteristics by using communications software which allows customised programming. The pilot valve system can be used equally for single and double-acting drives. It is characterised by a defined safety feature in case of failure of the electrical or pneumatic power supply and possesses an enormous air capacity range with pressure supply up to 7 bar.

1）Compact and robust design
2）Easy to start using Tune function
3）Dynamic positioning system with no air consumption in controlled state
4）AS-Interface Fieldbus (optional)
5）Mounting acc. to IEC 534-6 / VDI VDE 3845 or Remote
