>>>>>型號:1756-L72 可編程自動化控制器 支持控制器冗余

【功能描述】

Allen-Bradley 1756-L72 是一款ControlLogix系列可編程自動化控制器（PAC）。它具有用于數據和邏輯的 4 MB 用戶存儲器以及 0.98 MB I/O 存儲器。該控制器隨附一個 1 GB SD 卡 1784-SD1，可用作可選的非易失性存儲器存儲器。如果存儲空間不足以供您使用，您也可以通過 2-1784-SD2 卡將其升級到 2 GB。建議將 SD 卡安裝到控制器上，并且僅使用羅克韋爾自動化銷售的 SD 卡，因為這些卡已經過全面測試，可與控制器配合使用。使用其他 SD 卡會帶來數據丟失或損壞的風險。SD 卡主要用于存儲發(fā)生故障時自動寫入的診斷數據。羅克韋爾自動化將這些數據用于故障排除目的。1756-L72 控制器還配備了三個電容器儲能模塊。1756-ESMCAP/1756-ESMCAPK 是每個控制器中都提供的可拆卸模塊。另一個可拆卸模塊是 1756-ESMNSE/1756-ESMNSEK，它沒有剩余的 WallClockTime 備用電源。唯一不可拆卸的模塊是 1756-ESMNRM/1756-ESMNRMK，它有助于防止使用 USB 連接和 SD 卡來幫助保護控制器。

您可以將 1756-L72 控制器與特定模塊一起使用，以創(chuàng)建 Armor ControlLogix 控制器。當與相似的控制器配對并位于同一 ControlNet 網絡中時，它可以支持控制器冗余。與此控制器兼容的 ControlLogix 機箱包括 1756-A4、1756-A4K、1756-A7、1756-A7K、1756-A10、1756-A10K、1756-A13、1756-A13K、1756-A17 和 1756-A17K。它還具有 1 個全速 USB 2.0 端口和一個 4 個字符的字母數字顯示屏，供您查看其當前狀態(tài)。1756-L72 控制器提供多種通信選項，包括 Data Highway Plus、DeviceNet、Ethernet/IP、遠程 I/O、SynchLink、ControlNet 以及第三方過程和設備網絡。該控制器具有 30 伏的連續(xù)隔離電壓，并在 500 伏交流電下進行了 60 秒的型式測試。它在 1.2 V DC 時的電流消耗為 5 mA，在 5.1 V DC 時的電流消耗為 800 mA。1756-L72 控制器的功耗為 2.5 瓦，散熱為 8.5 BTU/小時。控制器的存儲溫度范圍為 -40 至 85 攝氏度，而其工作溫度范圍為 0 至 60 攝氏度。它在 10 到 500 赫茲時具有 2 G 的振動、30 G 的操作沖擊和 50 G 的非操作沖擊。Allen-Bradley 1756-L72 屬于最新的 ControlLogix 產品類別。

【英文介紹】

The Allen-Bradley 1756-L72 is a ControlLogix series programmable automation controller (PAC). It has 4 MB of user memory for data and logic and 0.98 MB of I/O memory. The controller comes with a 1 GB SD card 1784-SD1, which can be used as an optional non-volatile memory memory. If the storage space is not enough for you, you can also upgrade it to 2 GB with the 2-1784-SD2 card. It is recommended to install SD cards to the controller and only use SD cards sold by Rockwell Automation, as these cards have been thoroughly tested to work with the controller. Using other SD cards carries the risk of data loss or corruption. The SD card is mainly used to store diagnostic data that is automatically written when a fault occurs. Rockwell Automation uses this data for troubleshooting purposes. The 1756-L72 controller is also equipped with three capacitor energy storage modules. The 1756-ESMCAP/1756-ESMCAPK is a detachable module provided in each controller. Another detachable module is the 1756-ESMNSE/1756-ESMNSEK, which has no remaining WallClockTime backup power. The only non-detachable module is the 1756-ESMNRM/1756-ESMNRMK, which helps prevent the use of USB connections and SD cards to help protect the controller.

You can use the 1756-L72 controller with specific modules to create Armor ControlLogix controllers. When paired with similar controllers and located on the same ControlNet network, it can support controller redundancy. ControlLogix chassis compatible with this controller include 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17, and 1756-A17K. It also has a full speed USB 2.0 port and a 4-character alphanumeric display for you to view its current status. The 1756-L72 controller offers a variety of communication options including Data Highway Plus, DeviceNet, Ethernet/IP, Remote I/O, SynchLink, ControlNet, and third-party process and device networking. The controller has a continuous isolation voltage of 30 volts and was type-tested for 60 seconds at 500 volts AC. It has a current consumption of 5 mA at 1.2 V DC and 800 mA at 5.1 V DC. The 1756-L72 controller has a power consumption of 2.5 watts and a heat dissipation of 8.5 BTU/ hour. The controller has a storage temperature range of -40 to 85 degrees Celsius, while its operating temperature range is 0 to 60 degrees Celsius. It has a vibration of 2 G, an operational shock of 30 G and a non-operational shock of 50 G at 10 to 500 Hz. Allen-Bradley 1756-L72 belongs to the newest ControlLogix product category.
