>>>>>型號(hào):1756-L71 可編程自動(dòng)化控制器 配有三個(gè)電容儲(chǔ)能模塊
【功能描述】
Allen-Bradley 1756-L71是ControlLogix可編程自動(dòng)化控制器。它有2 MB的用戶內(nèi)存可用存儲(chǔ)空間和0.98 MB的I/O內(nèi)存。它還有一個(gè)板載4字符字母數(shù)字顯示器,便于監(jiān)控運(yùn)行時(shí)間和模塊信息以及控制器診斷。它有一個(gè)開(kāi)放式外殼和一個(gè)內(nèi)置的2.0全速USB端口??捎玫耐ㄐ胚x項(xiàng)包括DeviceNet、ControlNet、EtherNet/IP、遠(yuǎn)程I/O Data Highway Plus、第三方過(guò)程和網(wǎng)絡(luò)以及SynchLink。它還配有1 GB的非易失性內(nèi)存,但您可以使用1784-SD2將其升級(jí)到2 GB。建議將SD卡安裝在控制器中。
1756-L71控制器配有三個(gè)電容儲(chǔ)能模塊,其中兩個(gè)是可拆卸的。它在1.2伏DC下的電流消耗為5毫安,在5.1伏DC下的電流消耗為800毫安。1756-L71控制器還具有30伏的持續(xù)隔離電壓、2.5瓦的最大功耗和8.5 BTU/小時(shí)的熱耗散。它的最大模擬I/O、數(shù)字I/O和總I/O分別為4,000、128,000和128,000。它的工作溫度范圍為0至60攝氏度,儲(chǔ)存溫度范圍為-40至85攝氏度。它周圍的最高氣溫為60攝氏度,相對(duì)濕度為5%到95%。該控制器在10到500赫茲時(shí)的振動(dòng)為2G,工作時(shí)的沖擊為30G,非工作時(shí)的沖擊為50G,安裝SD卡后下降到45G。其他控制器可能要求用戶理解第一PLC寄存器的具體字節(jié)和位,以便開(kāi)始尋址程序元素。對(duì)于1756-L71,用戶只需插入一個(gè)程序單元,并選擇I/O物理連接的邏輯通道。在其它PLC中,用戶可能會(huì)發(fā)現(xiàn)需要將一個(gè)寄存器移到另一個(gè)寄存器,以啟動(dòng)轉(zhuǎn)換和處理,從而獲得模擬數(shù)據(jù)。該控制器只需要用戶找到I/O信號(hào)物理終止的邏輯通道。

【英文介紹】
Allen-Bradley 1756-L71 is a ControlLogix programmable automation controller. It has 2 MB of user memory available storage and 0.98 MB of I/O memory. It also has an onboard 4-character alphanumeric display for easy monitoring of uptime and module information as well as controller diagnostics. It has an open case and a built-in 2.0 full speed USB port. Available communication options include DeviceNet, ControlNet, EtherNet/IP, Remote I/O Data Highway Plus, third-party processes and networks, and SynchLink. It also comes with 1 GB of non-volatile memory, but you can upgrade it to 2 GB with the 1784-SD2. You are advised to install the SD card in the controller.
The 1756-L71 controller is equipped with three capacitive energy storage modules, two of which are removable. It has a current consumption of 5 mA at 1.2 volts DC and 800 mA at 5.1 volts DC. The 1756-L71 controller also has a continuous isolation voltage of 30 volts, a maximum power consumption of 2.5 watts, and a heat dissipation of 8.5 BTU/ hour. Its maximum analog I/O, digital I/O and total I/O are 4,000, 128,000 and 128,000, respectively. It has an operating temperature range of 0 to 60 degrees Celsius and a storage temperature range of -40 to 85 degrees Celsius. The maximum temperature around it is 60 degrees Celsius and the relative humidity is 5 to 95 percent. The controller has a vibration of 2G at 10 to 500 Hz, a shock of 30G when working, 50G when not working, and a drop to 45G after the SD card is installed. Other controllers may require the user to understand the specific bytes and bits of the first PLC register in order to begin addressing program elements. For 1756-L71, the user simply plugs in a program unit and selects the logical channel where I/O is physically connected. In other PLCS, users may find it necessary to move one register to another in order to initiate conversion and processing to obtain analog data. The controller only requires the user to find the logical channel where the I/O signal is physically terminated.
