VAC定位器D400系列介绍

VAC(BLX)定位器D400系列功能介绍

VAC D400是一种基于微处理器的“智能”仪器，可安装在旋转或线性气动执行器上，以实现精确的定位器控制。该装置虽然精确，性能先进，但易于安装，校准，并且经过良好过滤的空气和适当的维护，可以提供非常准确和无故障的服务多年。通过本地按钮校准和LCD，基本设置和校准不需要昂贵的手持设备。D400系列应用和通信可与Hart，Foundation Fieldbus或Profibus通信一起使用，符合最新的行业标准。D400的“效率”不仅体现在其基于微处理器的技术和精度上，而且还体现在气动空气处理中，其中空气消耗保持在最低水平。

•基于微处理器的阀门定位器

•用户友好的菜单驱动编程，带LCD显示屏

•本地按钮配置 - 无需手持设备或PC

•低空气消耗和经过验证的可靠机械设计

•模块化设计 - 可提供位置反馈，微动开关和“Fail Freeze”选项。用于旋转或线性安装的相同单元。

•铝制外壳 -Nema 4X IP 65外壳-标准-静电浸渍清漆，带有炉子硬化的环氧树脂。

•独特的自适应控制功能可以增强阀门/执行器组件，实现最大程度的控制，而不会扰乱过程。

•提供ATEX-FM-CSA-IEC-Ex认证

The VAC D400 is a microprocessor-based, “intelligent” instrument that can be mounted to rotary or linear pneumatic actuators for accurate positioner control. This unit, while sophisticated in its accuracy and performance, is simple to mount, calibrate, and with well-filtered air and proper maintenance, can provide very accurate and trouble-free service for many years. With local push-button calibration and LCD, no expensive handheld devices are needed for basic set up and calibration. Available with Hart, Foundation Fieldbus, or Profibus communication, the D400 range of applications and communications meets the latest industry standards. The “efficiencies” of the D400 are not only in its microprocessor-based technology and accuracy but also in the pneumatic air handling where air consumption is kept to a very minimum.

• Microprocessor based valve positioner

• User-friendly, menu-driven programming with LCD Display

• Local push-button configuration—no handheld device or PC necessary

• Low air consumption and proven dependable mechanical design

• Modular design—available with position feedback, micro switches and “Fail Freeze” options. Same unit for rotary or linear mounting.

• Aluminum Housing—Nema 4X IP 65 Enclosure—Standard—Electrostatically dipped varnish with stove-hardened epoxy resin.

• Unique adaptive control feature offers the ability to enhance valve/actuator package for maximum control without upsetting the process.

• ATEX-FM-CSA-IEC-Ex approvals available
