描述

Allen-Bradley 1756-L72 是 ControlLogix 系列可编程自动化控制器 （PAC）。它具有用于数据和逻辑的可用 4 MB 用户内存和 0.98 MB I/O 内存。控制器随附一个 1 GB SD 卡，即 1784-SD1，您可以将其用作可选的非易失性内存存储器。如果存储空间不足以供您使用，您还可以通过 1784-SD2 卡将其升级到 2 GB。建议将 SD 卡安装到控制器上，并且仅使用 Rockwell Automation 销售的 SD 卡，因为这些卡已经过全面测试，可以与控制器配合使用。使用其他 SD 卡会带来数据丢失或损坏的风险。SD 卡主要用于存储故障发生时自动写入的诊断数据。罗克韦尔自动化使用这些数据进行故障排除。1756-L72 控制器还配备了三个电容储能模块。1756-ESMCAP/1756-ESMCAPK 是每个控制器中可用的可拆卸模块。另一个可拆卸模块是 1756-ESMNSE/1756-ESMNSEK，它没有剩余的 WallClockTime 备用电源。唯一不可拆卸的模块是 1756-ESMNRM/1756-ESMNRMK，它有助于防止 USB 连接和使用 SD 卡来帮助保护控制器。

您可以将 1756-L72 控制器与特定模块一起使用，以创建 Armor ControlLogix 控制器。当与类似的控制器配对并位于同一 ControlNet 网络中时，它可以支持控制器冗余。与此控制器兼容的 ControlLogix 机箱为 1756-A4、1756-A4K、1756-A7、1756-A7K、1756-A10、1756-A10K、1756-A13、1756-A13K、1756-A17 和 1756-A17K。它还具有 1 个全速 USB 2.0 端口和一个 4 个字符的字母数字显示屏，供您查看其当前状态。1756-L72 控制器提供多种通信选项，包括 Data Highway Plus、DeviceNet、Ethernet/IP、Remote I/O、SynchLink、ControlNet 以及第三方进程和设备网络。该控制器的连续隔离电压为 30 伏，并在 500 伏交流电下进行了 60 秒的型式测试。它在 1.2 伏直流电下的电流消耗为 5 mA，在 5.1 伏直流电下的电流消耗为 800 mA。1756-L72 控制器的功耗为 2.5 瓦，其热耗散为 8.5 BTU/小时。控制器的存储温度范围为 -40 至 85 摄氏度，而其工作温度范围为 0 至 60 摄氏度。它在 10 到 500 赫兹时的振动为 2 G，操作冲击为 30 G，非操作冲击为 50 G。

Description

Allen-Bradley 1756-L72 is the ControlLogix family of programmable automation controllers (PACs). It has 4 MB of available user memory and 0.98 MB of I/O memory for data and logic. The controller comes with a 1 GB SD card, the 1784-SD1, which you can use 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 1784-SD2 card. It is recommended to install SD cards to the controller and only use SD cards sold by Rockwell Automation as these 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. The 1756-L72 controller is also equipped with three capacitive energy storage modules. The 1756-ESMCAP/1756-ESMCAPK is a detachable module available 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 USB connections and uses an SD card 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. The ControlLogix chassis compatible with this controller are 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 VDC and 800 mA at 5.1 VDC. 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 at 10 to 500 Hz, an operational shock of 30 G, and a non-operational shock of 50 G.
