BT200 BRAIN手操器是一種便攜設(shè)備，針對采用BRAIN通信協(xié)議的設(shè)備，對其進行設(shè)定、更改、顯示和打印參數(shù)，如工位號、輸出模式、范圍等。這款手操器還可以監(jiān)視I/O值和自診斷結(jié)果，設(shè)定恒定電流的輸出以及進行調(diào)零。當(dāng)系統(tǒng)啟動或維持操作狀態(tài)時，只需連接設(shè)備的4~20 mA DC信號線或ESC(信號調(diào)節(jié)通信卡)上的專用接口，即可執(zhí)行這些功能。
  特性: BT200 BRAIN手操器 As a portable terminal, the Model BT200 BRAIN TERMINAL is used in combination with equipment using brain communication for setting, changing, displaying and printing out parameters such as tag number, output mode, and range, through simultaneous communication. It also monitors I/O values and self-check results, sets constant-current output , and allows zero adjustments. The Model BT200 BRAIN TERMINAL is used by connecting it between 4 to 20 mA DC signal transmission lines of the equipment or to a dedicated connector on the ESC (Signal Conditioner Communication Card) when the system is started up or maintained.
    FEATURES
  Online monitoring and communication
The modulated communication signal does not interrupt the 4 to 20 mA DC signals during communication.
  Common to all Yokogawa’s equipment
The Model BT200 BRAIN TERMINAL works with all equipment that uses BRAIN communication.
  Easy of use
A large display (21 characters by 8 lines) eases setup and alteration procedures in English prompting interactive sequences.
   Diagnostics/security with error messages
• Self-check function • Security code protection of setpoints • Low battery voltage alarm • Automatic power-off
   Printer
(BT200-P00) Printer prints out tag numbers and other parameters on the spot.
