Allen-Bradley 1756-L72是ControlLogix系列可编程自动化控制器(PAC)。它有一个4 MB的用户内存用于数据和逻辑，还有0.98 MB的I/O内存。控制器配有一个1 GB的SD卡，1784-SD1，您可以将它用作可选的非易失性存储器。如果存储空间不够用，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，并且只使用Rockwell Automation出售的sd卡，因为这些sd卡已经过充分测试，可与控制器配合使用。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控制器还带有三个电容储能模块。1756-ESMCAP/1756-ESMCAPK是每个控制器中都提供的可拆卸模块。另一个可移动模块是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SD卡的使用，以帮助保护控制器。

您可以将1756-L72控制器与特定模块一起使用，创建Armor ControlLogix控制器。在同一个ControlNet网络中与类似的控制器配对时，它可以支持控制器冗余。与此控制器兼容的ControlLogix机箱有1756-A4、1756-A4K、1756-A7、1756-A7K、1756-A10、1756-A10K、1756-A13、1756-A13K、1756-A17和1756-A17K。它还有一个全速USB 2.0端口和一个4字符字母数字显示屏，供您查看其当前状态。1756-L72控制器有多种通信选项，包括Data Highway Plus、DeviceNet、Ethernet/IP、远程I/O、SynchLink、ControlNet和第三方过程和设备网络。该控制器具有30伏的连续隔离电压，并在500伏交流电下进行了60秒的型式测试。它在1.2伏DC下的电流消耗为5毫安，在5.1伏DC下的电流消耗为800毫安。1756-L72控制器的功耗为2.5瓦，散热为8.5 BTU/小时。控制器的储存温度范围为-40至85摄氏度，而其工作温度范围为0至60摄氏度。它在10至500赫兹时的振动为2 G，工作冲击为30 G，非工作冲击为50 G。

Allen-Bradley 1756-L72属于zui新的ControlLogix产品类别。该部件号代表ControlLogix控制器，具有4Mb用户内存和0.98 MB预分配I/O内存容量。

Allen-Bradley 1756-L72 is the ControlLogix family of programmable automation controllers (PACs). It has a user memory of 4 MB for data and logic, and 0.98 MB of I/O memory. The controller comes with a 1 GB SD card, 1784-SD1, which you can use as optional non-volatile memory. If you run out of storage space, 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 fully 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 also comes with three capacitive energy storage modules. The 1756-ESMCAP/1756-ESMCAPK is a detachable module provided in each controller. Another removable 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 the use of SD cards to help protect the controller.

You can use the 1756-L72 controller with a specific module to create an Armor ControlLogix controller. It can support controller redundancy when paired with similar controllers in the same ControlNet network. 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 see its current status. The 1756-L72 controller has 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 volts DC and 800 mA at 5.1 volts 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 at 10 to 500 Hz, a working shock of 30 G, and a non-working shock of 50 G.

Allen-Bradley 1756-L72 belongs to the newest ControlLogix product category. The part number stands for ControlLogix controller and has 4Mb of user memory and 0.98 MB of pre-allocated I/O memory capacity.
