控制器與指示器

橫河完整的產品線支持各種類型的控制應用。當前型號具備真彩色PV顯示屏和以太網連接功能。

  • 單回路控制器從傳感器接收溫度、流量、壓力和其他類型的測量讀數,並向閥門等控制元件發送相應指令,以便將這些值保持在期望範圍內。

  • UTAdvanced溫度控制器和數字顯示控制器採用易讀的14段大型彩色LCD顯示屏,並配以導航鍵,從而極大地提升了監視和操作性能。

  • UP35A/UP55A是1/4 DIN尺寸的可編程控制器,可以提供最多30個程序模型,同時監視8個PV事件、16個時間事件和8個報警。

  • UM33A可以提供多達9個報警輸出和輸入的校正功能(PV偏移、折線近似、折線偏移)。另外,也可選用24 V DC傳感器電源。

  • 通製連接在控制器前面板上的光纖通訊適配器,該軟件包可以設定控制器配定參數或者創建自定義計算程序。

線上研討會

    摘要:

    Modbus is a serial communications protocol originally published in 1979 for use with its Programmable Logic Controllers (PLC). It has since become a standard communication protocol and is now a commonly available means of connecting industrial electronic devices.

    In this Webinar we will get into the details of how to make Modbus work.

    Sign up and learn more about:

    • Modbus configuration: master/slave or client/server
    • Modbus deployment: steps to commissioning a new installation
    • The physical layer of Modbus: wiring
    • Modbus demonstrations
    摘要:

    Having knowledge of the different tuning elements and how to adjust them can help you bring these unruly loops under control. If you have the responsibility to keep the processes running at your plant or factory, this webinar will help you better understand the basics of PID control.

    In this webinar you will learn:

    • The purpose of each of the PID tuning elements
    • How adjusting the individual PID elements will affect the process
    • General PID profiles for pressure / flow loops
    • General PID profiles for temperature loops
    • An explanation of some supporting parameters like cycle time, manual reset, and anti-reset windup
