HARDY HI215/30WC A1-B12-E2稱重控制器技術資料

哈代總是以這種想法自豪。良好的產品設計使它更好。我們相信它更容易。為用戶學習新的項目/特征，而不是學習一個全新的產品。2151 / 30WC重量控制器如下就像以前一樣版本自1982。我們已經帶走了所有HI 2151／20WC重量的重要方面控制器及其附加特性及改進安裝、安裝和安裝的功能系統診斷比以前更容易。

產品設計

HI 2151/30的基本設計

在我們的多用途上保持不變重量控制器提供一個簡單的升級路徑。哈代理解困難更換單元和空間限制控制面板。這就是為什么我們設計我們的產品可以用一個舊的單位替換新的一個使用相同的外殼切口。顯示六位數阿爾法數字紅色LED顯示允許為了方便閱讀重量值使用作為閱讀菜單。30段條形圖是標準，可編程為各種模式和用途。

前面板前面板鍵盤和菜單跟隨相同的模式。當前菜單和特性已經增強，但前面板按鍵一直保持不變。沒有必要重新學習儀器的特點和功能當安裝了一個新的。

Hardy Process Toolbox

哈帝過程工具箱Hardy Process Toolbox

哈帝過程工具箱是一組生產率工具，支持各種工業稱重功能。每個工具都可以節省過程稱重應用的時間、提升精度和效率，并降低風險。工具包括消除振動的WAVERSAVER?、C2? 電子標定和INTEGRATED TECHNICIAN(Integrated Technician?) 等等。

HI 2151/30WC：

C2?（或eCAL）電子標定

哈帝C2?（在中國被稱為eCal）核心功能實現了稱重系統的快速簡單標定，而無需沉重的砝碼。

INTEGRATED TECHNICIAN? 操作員診斷

哈帝INTEGRATED TECHNICIAN(IT) 核心功能可幫助您對稱重系統進行故障排除，并且能通過儀器前面板或PLC診斷系統問題。這些測試會顯示系統重量、電壓、以及通過/未通過等信息以幫助確定并隔離儀器、接線和傳感器問題，同時降低維護成本。

WAVERSAVER?振動消除器

哈帝WAVERSAVER核心技術消除了周圍振動對電子秤稱重信號的影響，為快速、的重量讀數提供了真實的數據。

嵌入式網絡服務器

通過任何電腦瀏覽器都可以訪問儀器，使設置和診斷變得快速和簡單。從Ethernet網任何位置均可以使用嵌入式網絡服務器來設置所有參數。

安全記憶模塊 哈帝安全記憶模塊 (SMM) 使用標準的卡或記憶棒自動備份關鍵的稱重系統數據。借助SMM，您能夠在幾分鐘之內將數據轉移到另外的類似控制器上。也可以使用該卡輕松將您的控制器數據備份到PC機。安全記憶模塊存儲稱重控制器的關鍵配置、標定及設置數據，可以防止這些信息遭受破壞。 哈帝背面板可訪問擴展型SMM不僅僅是一張記憶卡；它還是連接SD產品的網絡媒介。SMM現在使用標準安全數字 記憶卡，可輕松實現儀器之間的數據傳輸。SMM可通過PC機讀取。自動稱重系統數據備份 系統運行過程中，輸入一個新參數時，SMM會自動在其存儲器中更新并存儲稱重控制器的關鍵配置、標定及設置數據，可以防止這些信息遭受破壞。 方便的稱重系統數據轉移 通過將SMM安裝至新的儀器，可以（在同系列儀器上）恢復一臺儀器中的存儲數據。通過儀器的背面板可以方便地拆裝SMM。

HI2151/30WC稱重控制器

通用型稱重控制器

HI 2151/30WC通用型稱重控制器可用于多種過程稱重應用，包括配料、混料、檢重、灌裝/分料、力測量、重量料位控制及稱重速率監控。

作為獨立運行的產品，HI 2151/30WC可以控制多達8個設置點繼電器，（2個標準C型）并可通過模擬、串行、Allen-Bradley RIO、Profibus DP或BCD通訊傳輸數據。數據在6位14段LED顯示屏上以字母數字形式顯示，在30段柱狀圖顯示屏上以圖形顯示。稱重數據可以是凈重、毛重、變化率 (ROC)、保持峰值或累計重量值（單位：磅或千克）。

稱重控制器也可以用作生產控制系統的前端設備，通過用戶可選的標準串口（RS-232、RS-422/485）與可編程邏輯控制器 (PLC)、電腦及打印機交互。同時也可以選擇AllenBradley Remote I/O、模擬或Profibus接口與可編程邏輯控制器交互

稱重控制器內的20位數模轉換器每秒更新20次，顯示分辨率為985000。這使儀器能承受較大的“死載荷”和較大的稱重傳感器，同時仍有足夠精度進行重量測量和控制。可以從通信端口輸入命令，也可以通過本地前面板鍵盤輸入命令。可以鎖定部分按鍵，限制操作員的訪問并保護數據。

哈帝過程解決方案易于安裝、配置、調試、操作和維護，而且非常安全，能夠節省時間、成本、原材料和/或成品。

Input Device Option

Standard input power is 120 VAC + / - 10 percent.

Output Device Option

Analog Output (-B1)

The Analog Output is configured from the front panel or the serial port and set up by jumpers on the printed circuit card. The option allows the transmission of Gross, Net, Optional ROC, Peak or Total weight as 0-5V, 0-10V, 0-20mA or 4-20mA (or the reverse of these), and makes it possible to span these ranges over a portion of the weight data. Resolution is 16,000 counts, or the number of display counts available in the range selected, whichever is less. 

Two analog optional boards can be installed in each instrument. Both voltage and current data are available simultaneously.

Binary Coded Decimal (BCD) Output (-B2)

This BCD Option provides six digits of parallel weight data representing Net, Gross, Tare and the present front panel display. If all types of output data are requested, they will appear one after the other, ten milliseconds apart. The BCD option provides a 37 pin D-subminiature connector on a 6 inch cable.

Binary Coded Decimal (BCD) Output (-B5)

This BCD option provides six digits of parallel weight data representing Net, Gross, Tare and The Present Front Panel Display. If all types of output data are requested, they will appear one after the other, ten milliseconds apart. The BCD option provides a 40 pin connector on a 60 inch cable for use with either the optional - B6 or -B7 external termination boards.

BCD Single Termination Card (-B6)

The BCD Single Termination Card is an optional external interface point for a single BCD port signal line. The card is designed for use with a single HI-2151/30WC-B5 instrument.

BCD Quad Termination Card (-B7)

The BCD Quad Termination Card is an optional external interface point for up to four sets of BCD port signal lines. All terminal positions accept 20 to 26 gauge cable sizes. Additional terminal boards may be interconnected to allow multiple BCD ports to exist in a tri-state arrangement.

Remote I/O (RIO) Interface to the Allen-Bradley Network (-B8)

The RIO port allows bi-directional communications with Allen-Bradley Programmable Logic Controllers (PLC) and Small Logic Controllers (SLC). The HI 2151/30WC represents a quarter rack of discrete I/O (32 bits in the Logic Controllers output and input image files) to the Logic Controller and supports both discrete and block transfers of data. It can support up to 230.4 Kbaud transfer rates.

Binary Coded Decimal (BCD) Output (-B9)

This option provides six digits of parallel weight data representing Net, Gross, Tare and the present front panel display. If all types of output data are requested, they will appear, one after the other, ten milliseconds apart. This option provides a 24 inch cable for use with the HI 2151/30WC-WS wall mount controller.

PROFIBUS Interface Option (-B12)

Allows bi-directional communications to Profibus (Process Fieldbus) products including those made by Siemens, GE Fanuc and Texas Instruments. This interface supports PROFIBUS-DP (Decentralized Periphery) and processes both Selectable Predetermined and Block transfer commands. It supports up to 12 Mbaud transfer rates.

Dynamic Data Exchange (DDE) (-B14)

Allows bi-directional communications with a PC over the serial port using Windows? 3.x, Windows? 95, Windows? NT. The DDE links the HI 2151 series weight controllers to a Windows? based application software such as: Wonderware?, Visual Basic, Excel?, Lotus 1-2-3, or Quattro Pro?.

Control Options

Peak Hold (-C1)

Displays and stores the highest Gross weight value measured until cleared by the front panel Key pad or from a remote command. This option is generally used in testing to determine peak forces a product or material can withstand. It can also be used to track the highest force applied to the scale.

Rate-of-Change (ROC) (-C2)

The ROC option measures and displays the rate at which a material enters or is dispensed from the scale over a period of time. To develop ROC data, a register is used that is 21 entries in length. New weight values are inputted to the register at the rate of 1/20th of the time base. The first register is subtracted from the 21st Register. The 21st register is one time base older than the 1st register. The time frame can be set to units per second, minute or hour. A time base of discrete values is selectable from 1 to 1800.

Set Point Options

TTL(Transistor - Transistor Logic) Level Output (-D1)

Provides six TTL level outputs, rated at 500 milliamps per line. A mating connector with eight 24 gauge un-terminated wires, 60 inches long is also provide.

External Setpoint Relays Card (-D2)

This externally mounted card is equipped with six solid state triac relays. Individual relays can be configured as form A or form B by an on board dip switch. Each can be programmed to respond to the standard Net or Gross modes of operation or the optional ROC, Totalizer or peak hold modes. Each have individual setpoint, preact and deadband parameters. A 60 inch interface cable is provided. This option should not be used with the wall mount enclosure.

External Setpoint Relays Card (-D3)

The same as the -D2 option except that the length of the cable provided is six inches. This is designed to mounted in the HI 2151/30WC-WS-D3 wall mount enclosure.

NIST/NTEP Certification Mode Kit (-E3 except for -F4 wall mount)

The HI 21251/30WC is approved for National Institute of Standards and Technology (NIST) applications formally called the National Bureau of Standards (NBS), and certified under the National Type Evaluation Program (NTEP) for up to 10,000 counts when the NIST mode is activated. This option is required when products are to be directly sold based on weight readings of the scale. This kit includes special screws for sealing the instrument, a label plate, a NEMA 4 gasket and a NIST label.

Portable Display and Keypad (-E4)

The HI 2151/30XX-E4 option is used for local set-up, calibration and display of the blind remote version instrument, model HI 2151/30WC-BR.

Intrinsic Barrier Assembly (-F1, -F3 thru -F7)

The Intrinsic Barrier Assembly Option is used only with the wall mount Model HI 2151/30WC-WS. The option provides safety for Class I, II and III, Division I applications.
